PRODUCTS I N F O R M AT I O N S TAT I O N Tracklaying tips and techniques Track M any model railroaders discover a whole range of unfamiliar terms when they begin acquiring the track components to build a layout. Most of these terms match prototype track terminology and are clearly descriptive, while others require some explanation. The list which follows defines the most common trackrelated terms, including some that are often misused. AREA: The American Railway Engineering Association is the prototype railroad organization which establishes right-ofway material specifications and track construction standards. Ballast: The crushed rock used to hold track in position, spread weight, and provide drainage. B&B gang: A traveling railroad crew that specializes in bridge and building construction, maintenance, and repair. Bridge: A structure which supports a track passing over a depression in the terrain or a stream. A through bridge has a floor structure which supports the track between its side beams or trusses, while a deck bridge has its supporting structure below track level. Bridge guardrail: A set of heavy timbers or steel rails mounted inside the running rails on a bridge or other structure to keep derailed cars in line. Bridge pier: An intermediate support used between bridge spans. Bridge shoe: An iron or steel casting which transfers the weight of a bridge to its supports. One end is normally a solid mounting while the opposite end allows for expansion or contraction. Bumper: A braced, coupler-height blocking device which keeps cars from rolling off the end of a track. Smooth-flowing handlaid trackwork has been the hallmark of the Detroit Model Railroad Club’s O scale Detroit Union RR for over half a century. This view of Duncan Junction includes several regular turnouts, a crossing, a single-slip switch, and a double-slip switch.

More on our Web site Information on preventing derailments can be found at www.modelrailroader.com. Sectional track S o you opened that train set Christmas morning and couldn’t wait to get rolling. Chances are the set came with a circle or oval of track sections. While it’s pretty easy to put this stuff together and change it around, here are a few tips for getting top performance from sectional track. What it is Sectional track comes in curves, straights, and turnout (switch) sections in every scale. In HO scale the most common curves are 15", 18", and 22" radius, with 9" and shorter straights. Turnouts are normally no. 4s or 6s. Shorter fitter sections, such as half curves, 1⁄4 straights, and the like are often necessary to complete any layout more complex than an oval and are also available. Have a selection of them on hand so you don’t end up with a gaping hole in the main line. Most folks start by snapping together a circle or oval of track on the floor. After a while the rail joiners loosen and the track sections work apart, often from the weight of the train. The result is a spectacular derailment, with track and train sailing across the room. While fun at first this quickly wears thin and can play havoc with locomotives and cars. Also, if you’re running your trains on a carpeted floor the carpet fuzz will work its way into the locomotive mechanism and cause operational problems. To prevent these problems the traditional solution has been nailing the track to a solid surface such as a piece Fig. 1 TRACK AND ROADBED. Most manufacturers offer track with plastic roadbed sections, like this True-Track from Atlas. Fig. 2 PROPER JOINT. Track sections should fit together easily, without any obvious gaps in the joint between rail sections. Fig. 3 FORCING TRACK TO FIT. This is a common mistake with sectional track. Trains will have a tough time crossing this gap. Fig. 4 HIGH-RIDING RAIL. Note how one of these rails is sitting over the rail joiner. Make sure both rails are seated properly. PHOTOS BY BILL ZUBACK of plywood. This may not be the best choice as most beginners want to easily change the track arrangement. Sectional track is now made with plastic roadbed sections (fig. 1). The roadbed sections have interlocking tabs to hold the track securely in place and keep the trains above the floor enough to avoid those dreaded carpet fuzzies. Getting up and running Laying sectional track is pretty simple. Line up two pieces and slide them together. Make sure the ends of the rail are lined up properly and fit snugly together with little or no gap (fig. 2). If you’re using track with molded roadbed make sure the tabs lock securely between sections. Two tips: Don’t force the pieces. The most common mistake is forcing curve sections tighter than the designed radius. This produces a gap between sections and a kink in the rail that’s a sure ticket to derailments (fig. 3). Another common problem is letting one rail slip up and over the adjoining rail joiner (fig. 4). Make sure the rail is sitting in the joiner before pressing the two sections together. Turnouts Closure rails Switch machine Switch rod Frog Guardrails Fig. 5 TURNOUT COMPONENTS Points Watching a train chase its tail around a circle can get boring. The solution is to purchase some turnouts and additional track sections, which will enable you to vary the train’s route. It’s hard to have trouble with sectional turnouts. Perhaps the most important thing is to ensure the switch rod is correctly installed and the points throw freely. Figure 5 shows the basic components of a turnout. While the standard geometry of sectional track somewhat limits layout design options, for ease and simplicity it simply can’t be beat. Good luck! 1 Fig. 4 LAYING CURVES Laying flextrack on curves Bend track to curve, mark cut with hobby knife. Use rail nippers to cut longer rail ends flush CHRISTINE PAUL Fig. 1 CUTTING FLEXTRACK.

CHRISTINE PAUL Fig. 3 FILING RAILS. File the end and underside of the rail as well as the web so a rail joiner will slip on easily. ILLUSTRATION BY RICK JOHNSON G ood track is the main difference between a layout that’s fun to operate and one that gathers dust. Laying straight track is easy, but laying curves with flextrack can be tricky, especially when you need to join two sections of flextrack in the middle of a curve. It’s easy to introduce a kink, guaranteeing operating problems. Here are some tracklaying tips that work for me. Cutting and fitting flextrack You need a good set of rail nippers. To avoid damaging the cutting edges use them only for cutting rail. I happen to use Micro Engineering’s but other brands are available. To determine where to cut position the track and mark the rail with a knife. Figures 1 through 3 show how to cut the track and file the cut smooth. Laying curved track Because the rails start out the same length and the inside of a curve is always shorter than the outside, the inside rail will have to be cut. This isn’t all that difficult. For all but the tightest curves you’ll find you need to use more than one piece of track to complete the curve. But if you lay the curved track and then add a second piece on the curve you’ll likely end up with a kink. To prevent that problem start the curve by spiking down a piece of flextrack through the start of the curve, leaving the last 8" to 10" straight (fig. 4). Cut the rail ends flush, file smooth, and join the next section of track. Solder the joint while the track is still straight. Use rosin-core solder and a clean, hot iron. Heat the rail and touch the solder to the metal. The solder should take only a couple of seconds to flow. After the solder cools bend the track to the desired curve. Smooth trackwork is critical to enjoying model railroading. Take your time and you’ll be surprised at how precise your track can be. 1 Grades F. L. BECHT Capturing the image of a train climbing the grade is the goal of many modelers. This is Tehachapi Pass in California, circa 1973. 8" I ’ve yet to find one thing that confuses more model railroaders than grades. Sure, everyone knows what they are – essentially track going up or downhill. It’s translating that to the layout that trips folks up. ent erc 7" 4p 6" Rise (height above base 5" level) in 4" inches 3" t ercen 2.5 p ent 2 perc t en rc pe 1 2" 1" Doing the math The math for figuring out the percent of grade for a model railroad is almost ridiculously simple. The basic formula is the number of units of rise per 100 units of run (fig. 1). The “unit” can be any measure of distance, though the easiest one for us to use is inches. For example, a two percent grade climbs 2" for every 100" of travel. By the same token, a track that climbs 1" in 50" of travel or climbs 3" in 150" of travel is also a two percent grade. The length of the run is really immaterial, only the angle of the climb matters. Don’t let the grades get too steep as it’s amazing what a slight grade can do to a locomotive’s pulling power. Start by figuring on two or 2.5 percent. If you need to go steeper than that go for it but try keeping grades under four percent if at all possible unless you plan to run short trains or geared locomotives. 50" Fig. 1 PERCENTAGE OF GRADE 150" 100" Run (length of track) in inches 200" ILLUSTRATIONS BY RICK JOHNSON 3.

Fill in with additional risers as needed, checking with gauge to make sure there aren’t any steeper “hidden” grades Fig. 2 BUILD A GRADE Desired 2.5 percent grade Run – 50" BILL ZUBACK The grade gauge from K-Tool Products fits on a standard two- or four-foot level. Set the dial at the desired grade (here, 2.5 percent). Making the grade One way to add a grade to a flat tabletop layout is with the Styrofoam incline subroadbed from Woodland Scenics. These are precut subroadbed sections in two, three, and four percent grades. Glue them to the plywood and you’re ready to add roadbed and track. It’s important to make sure the grade you’re building matches the one you figured out on paper. The grade gauge (above) from K-Tool Products, is handy for this. It’s available through Walthers and most hobby shops. Set the desired grade and place the level on your subroadbed. When the bubble reads level the subroadbed is at the proper angle. To add grades to a long run I find it’s easiest to figure out what the starting and ending point elevations are, relative to the tops of the joists. Then I secure the risers and subroadbed at those heights and fill in the additional risers needed for support (fig. 2). While doing that I check the grade with the gauge, since I don’t want any hidden grades (undesired steeper grades within the length of the run) causing problems. Finally, keep an eye on ceiling height. It’s amazing how much elevation you gain with a long grade. If you’re not careful you may burst through the ceiling and end up on the living room floor. 1 Easy easements L aying tangent (straight) track is pretty straightforward but those curves can, well, throw you a curve. Equipment that enters a sudden curve is more likely to derail. And even if wheels stay on the rails the sight of a train jolting into a sudden curve can make even the most realistic layout look like a train set. Your trains will look better and long rolling stock will track more reliably if you add an easement between the straight and curved track. An easement is a gradual transition, or a very broad non-concentric curve, inserted between the tangent track and the circular curve. Obviously, you can’t have a true easement with sectional track, although if possible you might want to insert a broader radius curve, like a 22"-radius section, between the straight track and the 18"-radius sections. Whether you’re using flextrack or handlaying your track you’ll find easements will keep things running smoother and looking better. The “bent stick” method The prototype uses all kinds of fancy formulas to figure out easements, and you can spend a lot of time adapting those same formulas for model railroad use. But that’s hardly necessary. The Step 1: Mark center line of tangent (straight) track Co Step 2: Mark center line of curve using trammel. Leave offset between the lines where tangent is square with radius. Offset should vary with radius and length of easment: 3⁄8" for 18" radius to 1⁄2" for 30" radius, or greater for longer easements (see box) t cu tan ns Curve Length of radius Offset easement 3 3 6" 9 ⁄4" ⁄16" 1⁄ 4 " 10" 16" 3 12" 18" ⁄8 " 7⁄16" 16" 24" 1 18" 30" ⁄ 2" en Tang Constant curve t Offset between drawn lines rv e en Tang t Small brads to hold stick in place if needed Step 3: Lay flexible stick along tangent and curve, mark along stick Easement length should be divided equally on both sides of this point Easement en Tang LAYING OUT EASEMENTS t Step 4: Lay roadbed along marked center lines of track Easement ILLUSTRATIONS BY ROBERT WEGNER diagrams show how I plot easements using nothing more complex than a pencil and a flexible piece of wood. Start by drawing the center line of the tangent track directly on the subroadbed. To ensure a constant radius curve use a trammel, which is nothing more than a piece of wood (a 1 x 1 works fine) with a hole for a screw or nail at one end and holes big enough to clear a pencil every inch starting with your minimum radius and ending up with the largest practical radius. Or you can use a template made from styrene, Masonite, or cardstock, cut to the desired curve. Draw a circular curve of the desired radius. Don’t connect this line to the center line for the tangent track – instead leave a slight offset, about 1⁄2" to 3 ⁄4", between the two lines. The offset and length of the easement varies with the curve radius. For an 18"-radius curve the offset is 3⁄8", with a 12"-long easement. The offset is 1⁄2" for a 30"radius curve, with an 18"-long easement. Mark the point where the tangent is square with the radius and equally divide the length of the easement on both sides of that mark. Now you’re ready to mark the center line of the easement. Use a piece of flexible wood molding. Hold the wood along the center line of the tangent and bend it to match the radius of the curve you already marked. For very large curves you may need to temporarily drive a few small brads along the molding to hold it in place. Once you’re satisfied with the alignment trace along the molding with a pencil, creating a nice smooth transition. Remove the molding and lay your roadbed or track in place along the center lines. This is, admittably, a simple way to lay curved track with an easement. A detailed explanation of easements, complete with a table showing suggested measurements for various curves, can be found in John Armstrong’s Track Planning for Realistic Operation (Kalmbach). John also presents convincing arguments for using easements. 1 Laying roadbed JIM FORBES W hen it comes time to lay track for a first layout, many beginning modelers think that laying roadbed is a hassle and are tempted to skip the step and lay track directly on the plywood table or subroadbed. However, what they fail to realize is that model roadbed serves many important purposes. The first is appearance: Look at a real railroad main line and you’ll see how it’s elevated above the surrounding ground on roadbed and ballast. Model roadbed allows us to similarly raise the track profile, making the track look more realistic. Model roadbed also provides a smooth contour for ballast. The sloped shoulders help define the ballast profile. Other important reasons for using roadbed are that it provides a smooth, level base for track, and it also quiets JEFF WILSON Fig. 1 SPLITTING CORK. Cork strips are perforated at an angle down the middle, and the two halves must be peeled apart. You need to sand the rough edges after laying. The most common roadbed material is cork. It’s available from many manufacturers such as Busch, Faller, Midwest Products, and others. It’s easy to find, relatively inexpensive, and available in scales from N through G. Cork roadbed comes as a single piece that’s perforated down the middle and must be separated (see fig. 1). The samples shown are in HO scale, but installation of other sizes is the same. Peeling the two halves apart, flipping one half over, and placing the pieces side-by-side provides a beveled edge on each side. The beveled edge helps to recreate the proper ballast profile. Glue is the best way to install cork. Start by running a bead of white or yellow glue next to the track center line drawn on your subroadbed. Press the cork onto the glue, then use push pins or wire nails to tack the cork in place as shown in fig. 2. Don’t drive the nails all the way into the cork – once the glue dries the nails will be pulled out. Cork often has a burr along the beveled edges that can keep ballast from lying smoothly along the slope. To remove the burr, lightly sand it with a sanding block and coarse sandpaper. To provide a smooth roadbed, be sure to stagger the cork joints so they don’t fall directly above any subroadbed joints. It also helps to stagger the joints on the two halves of the cork. When laying track on cork, the heads of track nails should be just above the JEFF WILSON JEFF WILSON operations by insulating the track from the underlying wood base, which otherwise can act like a sounding board. Using traditional cork Fig. 2 GLUING AND TACKING. Run a bead of white glue along one side of the track center line, press the cork in place, and secure it until the glue dries. Fig. 3 ROADBED UNDER TURNOUTS. Start by laying the outside two pieces of cork following the track center lines. Then cut the inner two pieces to fit and glue them in place. ROADBED ALTERNATIVES I other manufactured roadbed prodn addition to cork, there are some ucts available. Each offers unique advantages as a base for laying model railroad track: AMI – Instant Roadbed – a selfadhesive uncured butyl rubber strip that sticks directly to the subroadbed. It can also be shaped to make roads and sidewalks. California Roadbed Co. – HomaBed – a manufactured Homasote product with several contour profiles available. It works well for handlaying track. Hobby Innovations – VinylBed – a single-piece roadbed made from multi-shaded gray granules of recycled vinyl. It is very flexible and has good sound absorption qualities. Tru-scale Models – Milled basswood roadbed. It is available with a smooth surface or with pre-gauged ties for handlaying track and comes in straight sections and various radius curves. Woodland Scenics – Track-Bed – a flexible single-piece spongerubber roadbed. It is easy to cut and also available in sheets for making yards. – Jeff Wilson ties. Driving the nails too deeply can buckle the ties and kink the track, shifting it out of alignment. Laying roadbed for turnouts Precut turnout pads are available in various sizes and scales from Midwest and IBL, but it’s also easy to cut even complex arrangements yourself. Start by laying cork strips along the outside of both the straight and diverging routes. Add the inside part of the straight route, using a hobby or utility knife to cut off the beveled edge where it will meet the other cork strip. Lay the remaining strip of cork in place and draw a cut line with a marker. Cut the cork and lay it in position as shown in fig. 3. Here, the joints don’t have to be perfect, as they’ll later be covered by ballast. Simply make sure that the cork is level so it will firmly support the track. With a little knowledge and practice, you’re now well on your way toward providing a smooth roadbed base for your trackwork! 1 PHOTOS BY JEFF WILSON From track plan to benchwork Y ou’ve managed to find the perfect track plan in a book or magazine, or you’ve spent hours at the drawing table or computer carefully drafting a track plan. The next step is transferring the track plan to your layout table or benchwork. If you’ve never done this before, the first thing you’ll probably learn is that – regardless of how carefully you’ve measured – track will almost always take up more room on the layout than it did on paper. It is important to take your time and be precise, as any miscalculation will hinder tracklaying. lines on the track plan to match those on your layout surface. Once the basic grid is drawn on the layout and track plan, the next step is to mark out the radii of curves. Figure 2 shows how to find and mark the center of the radii on the track plan. Transfer Tools and tricks One of the first steps in track planning is drawing a grid on the plywood (or whatever surface your layout top happens to be). As fig. 1 shows, a drywall T-square with a four-foot arm is invaluable for this. A 12" grid is usually sufficient, but for complex plans you might want to add grid lines at the 6" marks as well. It’s also important to draw grid Fig. 1 GRID ON TABLE. A drywall T-square with a four-foot arm works well for laying out a grid on the table. A 12" grid is sufficient for most track plans. Fig. 2 CURVE CENTERS. Measure to find the center point of each curve, then mark it on the track plan. Fig. 4 LAYING TURNOUTS. While turnouts can be trimmed for size, they must be kept in proper alignment. As you use the turnout templates, tape them in place to prevent the track from becoming misaligned. templates in 2" intervals from 18" to 44", and as the photo shows, there is different radius on each side of the template. Planning turnouts Fig. 3 CURVE TEMPLATES. These templates are especially handy for drawing broad curves. They can be made from styrene, hardboard, or thin plywood. the center point to the layout table, then use a compass to transfer the curve to the table. You can make a large compass by using an old wood yardstick. Holes in the yardstick at 1" intervals make handy guides for a pencil. However, some curves are too broad to easily use a yardstick, or the center of the curve may be well off the layout table. In this case curve templates work well (see fig. 3). My curve templates are about 40" long and made from large pieces of .060" styrene that I had on hand. You can also make them from hardboard (such as Masonite) or thin plywood. Cardboard will work, but it is not as durable as hardboard. I made my Probably the most difficult part of track planning is leaving enough room for turnouts. They always seem to take up more space than originally figured, and every manufacturer’s turnouts vary slightly in size and shape. Because of this, complex trackwork in published plans often doesn’t fit the same way on a layout. To remove the guesswork, make several paper turnout templates by placing turnouts on a photocopier, then running off as many copies as you need. Be sure to label them with the brand name and size. As you use templates, tape them in place, as shown in fig. 4. Alignment is the important thing – remember that you can trim turnouts to fit tighter areas as long as you maintain proper alignment and track center spacing. From paper to benchwork Large rolls of newsprint or brown craft (or wrapping) paper work well for laying out full-size plans. You can do this even before starting benchwork by laying the paper on the floor where the layout will go. Getting your track plan to the benchwork is a fun step in visualizing what your finished layout will look like. Work carefully and take your time, as the process is vital in getting track to fit properly, which will enhance operations and enjoyment. 1 PHOTOS BY JEFF WILSON Manual switch controls T rack switches – usually called “turnouts” in the modeling world – are the key trackwork component that make running our trains interesting. Part of reliable operation is to make sure that the points, the moveable part of a turnout, always stay put in the direction they’re set. Otherwise a train can end up on the wrong track, or worse yet, derail. There are many different ways to operate the points. Electric switch motors are popular and work well; however, many modelers use manual controls as they are reliable, inexpensive, and easy to install. The prototype and the model Let’s start with a look at a prototype (real) switch. The points are secured at one end to the switch rod. The switch rod extends under one stock rail to the switch stand as shown in fig. 1. The mechanism holds the points securely against one stock rail or the other, depending on how it’s set. Model switch points operate in similar fashion. Having a manual switch stand or ground throw might not seem necessary at first, but you’ll eventually find it important to have some type of mechanism to hold the points in place. N scale turnout Switch rod Manual ground throw Switch points HO scale turnout Stock rails Fig. 1 PROTOTYPE SWITCH STAND. On the real thing, the switch rod connects the points to the switch stand, which is operated by hand. Without positive locking, the points can creep away from the stock rails and cause a derailment. Ground throws Some model turnouts, like the Atlas HO and N scale turnouts in fig. 2, come with a manual switch controller already attached. These often look the same as above-table electric switch motors but without the wires. Although this type of mechanism works, it’s unsightly and bears little or no resemblance to anything found alongside a real switch. As you gain experience in the hobby you’ll find that for esthetic reasons, it’s best to discard this type of controller and change to a less conspicuous ground throw. Operating ground throws are made by Caboose Industries, NJ International, Rix, and others. You’ll find them in functional sizes from N through O scales. Although many tend to be a bit oversize compared to a real switch stand, these ground throws look much better than the manual controls in fig. 2, and they operate very well. Fig. 2 BASIC CONTROLLERS. These Atlas N and HO turnouts come with manual switch machines. Though they work well, the large mechanisms don’t look very prototypical. Installing a ground throw The procedure for installing a ground throw is simple. Start by determining which side of the turnout you want to position the ground throw. Next, check the unit’s mounting pin as styles vary among manufacturers. Caboose Industries’ throws, such as the no. 202 ground throw (shown in fig. 3 with an Atlas HO turnout), have a pin on the bottom of the operating rod, designed to fit in a hole on the turnout’s switch rod. If the switch rod doesn’t already have a matching hole, it’s easy to drill one to fit the pin. For good operation, the ground throw must sit at the proper height to match the level of the switch rod. As seen in the prototype photo, real switch stands rest on the turnout head blocks – long ties on either side of the switch rod. You can make extensions for model turnouts out of stripwood or styrene if you like, but in this case I simply added a thin piece of wood to shim the ground throw to the proper height. The shim can be glued in place and hidden when you ballast the track. To install the ground throw, set the lever of the ground throw so it’s at the halfway point and the switch rod is at its midpoint as well, as seen in fig. 4. Next, fasten the ground throw in place with small track nails or spikes. When secure, move the mechanism each way to make sure the points are held tightly in each position. The toggle spring method You can also make a latching device for your turnouts from wire. It’s another inexpensive project that’s easy to make and quick to install. Straighten out a small paper clip, then bend a portion of it into a Vshaped spring as fig. 5 shows. To install the spring, insert its long leg into a hole drilled through a tie near the throw bar. The short leg should then be set into a hole in the center of the throw bar. For the proper tension, the space at the open end of the V should be slightly longer than the distance between the holes in the throw bar and tie. The paper clip spring provides a toggle action that snaps the points into place when pushed by hand. Once you’ve installed and tested the spring, paint it black or dark brown so it blends in with the ties and ballast. With a little effort, you can quickly have smooth-working turnout controls, which will go a long way toward improving your layout’s operation. 1 Fig. 3 MOUNTING. Caboose ground throws have a pin that mounts in a hole on the turnout’s switch rod. If a matching hole is needed, it’s an easy task to drill one. Fig. 4 ALIGNMENT. Set the ground throw in place with the turnout switch rod and ground throw lever at their halfway points. Secure the ground throw in place with track nails or small screws. Fig. 5 TOGGLE SPRING. A simple spring made from a paper clip works well for controlling turnouts. After installing and testing the spring, paint it black or dark brown to blend in with the track ties. PHOTOS BY JEFF WILSON Grade crossings W e’re all familiar with the sight of flashing lights and descending gates as we approach the railroad tracks. These intersections, where railroads and roads cross each other, are known as grade crossings. They are an interesting feature of railroads that can be a focal point on our model railroads. The most common types of grade crossings on real railroads today (used on most new installations since the late 1960s) are prefabricated rubber-andconcrete crossings made up of panels that are secured to the ties. See fig. 1. Prior to prefabricated designs, the most commonly used material for crossings was hardwood with planks bolted in place over the ties. These can be found on all types of roads, from concrete and asphalt highways to gravel country lanes. Although wood crossings are being phased out, you can still find them in service in many locations. Paved grade crossings are also in common use, with asphalt laid up to and between the rails. Fig. 1 PROTOTYPE CROSSING. Prefabricated crossings, like this rubber one, are the most common type in use today. Fig. 2 KITS. Two HO models available are the Walthers plastic kit for a rubber crossing and the Blair Line timber crossing. Modeling grade crossings You can either model your own grade crossings or use commercial kits. Modelers in HO can choose from rubber crossings from Accurail (no. 117) or Walthers (no. 933-3137) as well as a wood crossing from Blair Line (no. 165); Fig. 3 CROSS-SECTION Crossing material between rails should be below railheads Carve material to clear spike heads ILLUSTRATION BY RICK JOHNSON Fig. 8 ROAD. Add the road material so that it is flush with, but not higher than, the top Fig. 4 PAINTING. Paint the ties and insides of the rails the color of the crossing material to Fig. 5 CUTTING. The Walthers grade crossing can be cut to almost any length needed, so even wide highways aren’t a problem. Fig. 9 ASPHALT CROSSING. You can make an asphalt crossing by simply continuing the road material across the rails. Fig. 6 CARVING. Carve away any material that interferes with the crossing fitting next to the rail. Fig. 7 PLACING. After test-fitting the parts, place drops of CA on the ties and set the crossing in place. N scale modelers don’t yet have prefab rubber crossings, but timber models are available from Blair Line (no. 65) and Cal Freight (no. 1185). Figure 2 shows two HO crossings: the Walthers rubber crossing, made of unpainted injection-molded styrene, and the Blair Line timber crossing, made from stained wood. Whether using a kit or making a crossing on your own, it’s important that the crossing materials not interfere with operation. See fig. 3. The material on the outside of the rails should butt firmly against the rails but shouldn’t be any taller than the railheads. Keep the material between the rails below railhead level to avoid snagging uncoupling pins or otherwise interfering with operations. It’s easiest to add grade crossings before you have ballasted the track, but you can add crossings over ballasted track as well – just make sure no stray pieces of ballast interfere with the crossing materials. Paint the ties and insides of the rails to match the crossing materials. See fig. 4. This helps disguise the fact that modeled flangeways must be noticeably wider than those on real crossings. The Walthers crossing is made for a very wide street, but the pieces can be cut to any length to match the width of the road material. See fig. 5. I cut mine to 23 feet to match my styrene highway, then painted it black. The wood crossing requires some prep work as well. Carve away enough wood from the bottoms of the outside pieces (entire length) on the side where the timbers meet the rail. See fig. 6. If you don’t do this, the track spikes will keep the pieces from butting firmly against the rails. The Walthers crossing is molded to fit over the ties. Test-fit each piece to make sure it fits properly. Add drops of medium or thick cyanoacrylate adhesive to the ties, then press the pieces in place as in fig. 7. Once the crossing is in place, test it by running a locomotive and car through it to make sure that nothing catches. A National Model Railroad Association standards gauge is handy for checking the flangeway widths to make sure they are correct. Now you can add the road material. I cut my roads from pieces of .060" sheet styrene, painted them gray, and weathered them with black chalks, as shown in fig. 8. You can also make your own asphalt crossing. To do this, run the road material (styrene in fig. 9) up to the outside of the rails, then cut a thin piece to fit between the spikes and the rails. This is also the easiest method to use for curved grade crossings, as the road material can be cut to match the curve of the track. You can also make wood crossings using scale stripwood. Curved crossings are made by cutting the stripwood in six- or eight-foot lengths and placing them end-to-end at a slight angle. Finish the scene by adding ballast and scenery materials. You’ll appreciate the added realism that these grade crossings bring to a layout. 1 PHOTOS BY JEFF WILSON Cleaning track W hen it comes to nuisances that interfere with running trains, dirty track is probably the number one offender. Running trains is the goal – not nudging stalled engines. By cleaning track regularly, you can keep your trains running smoothly. Dirty track is caused by a combination of dirt and dust that accumulates on railheads. In addition, an oxide forms on both brass and nickel-silver rail over time. The oxide on brass rail inhibits electrical contact, but the oxide on nickel-silver rail is conductive. For this reason I recommend using nickelsilver rail. An important factor in keeping track clean is eliminating sources of dust and dirt. Among the best ways to do this is to put your layout in a finished room. If you have a layout in a basement or attic, install a ceiling (solid or suspended) in the entire room or just over the layout to minimize the amount of dust and dirt that gets on the rails and scenery. You’ll also want to isolate the layout from sources of dust, such as workshops. Keeping windows closed also helps, as open windows let in a great deal of dust. Smoking also results in grime on the track, so if you must smoke, do it away from your layout. Fig. 1 TRACK CLEANING TOOLS. Many products are made for cleaning track, including (clockwise from lower right) the Roco no. 10002 cleaning block, Walthers Bright Boy (no. 949-521), Centerline track cleaning car, Life-Like no. 1415 track cleaning fluid, and Aztec track cleaning car. Methods of cleaning track Cleaners fall into two broad categories: track cleaning cars, which are designed to do the work for you; and products that require you to do the cleaning work. In general, I’ve found that when starting with extremely dirty track – such as newly laid or painted track, or a layout that hasn’t been run in several months – the only way to get track truly clean is with elbow grease and an abrasive cleaning block such as the Walthers Bright Boy or Roco cleaning block seen in fig. 1. Rub the block along the rails, as shown in fig. 2, being careful not to bump into nearby details. Also use care around turnouts and other complex track areas, but make sure the points, frog, and other rails in these areas are thoroughly clean. Follow this with a cloth, wiping the rails to remove any residue left behind from the cleaning block. Going over the Fig. 2 ABRASIVE CLEANERS. Abrasive cleaners, such as the Roco cleaning block, are effective for extremely dirty track. track with a vacuum to suck up stray dust, dirt, and ballast is also helpful. Don’t use sandpaper or emery paper to clean track. The abrasives in these are harsher and leave small grooves in the railheads, which accumulate dirt, dust, and oxidation. The net result is impaired electrical contact. Liquid track cleaners are another option. With these, you brush the cleaner on, then wipe the rails with a cloth. Some products are made specifically for cleaning track, such as the Life-Like track cleaner in fig. 1. Other fluids that work well are Goo Gone and TV tuner cleaner. Keeping it clean Once you have the track clean, the best way to keep it clean is to run trains frequently. Although I have no scientific proof, I’ve found – and I’ve talked to other modelers who agree – that metal wheelsets and track tend to polish each other, much in the way that well-used wheels and rail stay shiny in real life. Track cleaning cars also keep track clean. There are two main types: those that use a wet pad and those that use a dry abrasive wheel (some use both). The Centerline car in fig. 1 uses a cloth wrapped around a heavy brass roller. The cloth is moistened with track cleaning fluid and the car pushed or pulled around the layout. Some modelers use these in pairs, with the lead one wet and the trailing one dry. They are available in scales from N to G. The Aztec car in fig. 1 uses a pair of abrasive wheels to clear grime off the tracks. The wheels are set at a slight angle to the rails to increase the drag. Versions of these cars are available in both HO and N scales. You can make your own inexpensive track cleaning car using a small piece of Masonite hardboard, as fig. 3 shows. A pair of galvanized roofing nails glued with epoxy to the Masonite fit through holes drilled in the floor of a boxcar. The weight of the pad is enough to hold it to the rails, so it polishes the rails as the car moves along. Because the pads aren’t permanently attached to the car, you can remove them at any time. These pads won’t clean the track if it’s especially dirty, but they help maintain track already cleaned. The pads have to be sanded clean before each cleaning (or operating) session, otherwise they end up just spreading dirt. Model railroading is the most fun when you don’t have to worry about operational problems, and keeping your track clean will make that possible. 1 TWO PHOTOS BY JIM FORBES Fig. 3 MASONITE CARS. Simple – and effective – cleaning cars can be made by gluing a pad of Masonite hardboard to a couple of nails. Drill holes in the floor of the car to clear the nails. The pads can be sanded clean when they become dirty. AFV/13 Nov/Dec 03 20/10/03 4:26 pm Page 14 Train Spotting Introduction from central Russia in late spring and early 506. during March 1944.

The limit is just set by hard winter. the builder and his/her sanity. Also, for the painting aspect, all the techniques used for Building the little Tiger bigger models can be applied to these little gems. Like many of us, I started in AFV modelling by building and painting 1/72 kits. Soon, I Probably, the current leader in 1/72 moved to 1/35 because these “big” tanks injected plastic kits is Revell. The quality of were more impressive, better detailed and their most recent releases is astounding I thought that they allowed my modelling and small-scale modellers await each new skills more scope to develop. Thus, I one with great expectation. Anyway, one relegated the 1/72 scale and saw it as a has to be cautious, since among these “starting point” and the models in this “state of the art” kits are re-editions of scale as toy like. Recently I discovered older Esci or Hasegawa moulds which are some of the newer 1/72 kits and was not up to the same standards. astonished. All the finesse and quality of the best 1/35 kits is there, but in a tiny size The Tiger I depicted in this article and they are fun and quick to build. Out of (reference 03516) is an example of one of the box they give excellent representations these new generation Revell kits. This of the “real thing” but they also leave brand has in it’s 1/72 catalogue two Tiger I 15 AFV/13 Nov/Dec 03 20/10/03 4:26 pm Page 16 1 kits. This one represents a mid/late vehicle while the other (ref. 03508) allows you to build an “African” early Tiger I. Both kits share most of their parts, with one sprue specific for each type of tank, and their overall quality is excellent. I decided to build my model as a mid Tiger I with rubber tyred wheels. This type is provided in the box (they are common to the “African” version) along with the all steel type, but curiously enough, they are marked as “not for use” in the instruction sheet and thus no advice for their placement is given. Photographs and literature have to be checked for their correct installation, a minor task. A shortcut taken by Revell in this area is that the double wheels are represented by a single, thicker one, much in 2 the same way as Tamiya did with its seventies 1/35 Tiger I. This apparent shortcoming is barely noticeable when all the running gear and tracks are installed. As I have already mentioned, I decided to finish my Tiger as one belonging to the s.Pz.Abt. 506. in Russia during spring 1944. The most remarkable feature of this unit’s markings at this period was the large unit symbol on the rear of the turret bin, consisting of a “W” (after its former commander, Major Willing) with the shield and the tiger. The colour of the “W” and the turret numbers denoted the company (Stabs-green, 1. Kp.- white, 2. Kp.-red and 3. Kp.-yellow). I chose this unit because the 506. crest is included on the decal sheet.The construction work progressed with no problems. There are plenty of aftermarket products available for 1/72 models including the Tiger I, but I decided to follow the “homemade way”. 3 Photos 1 to 4 First of all, the version I chose for my Tiger required a zimmerit coating. I did this by engraving with a small screwdriver the surfaces that had been previously softened with liquid cement. Two or three applications of glue were given in a relatively small area and after a few seconds, the pattern was engraved with the screwdriver. It may be necessary to check the degree of softening of the plastic and to apply more liquid cement before starting the engraving work. It probably would be advisable to practice a little bit first on non-visible surfaces, such as the interior or the underside of the hull. When the softened area is done, the process is repeated on the next area until the entire surface is completed. When the glue is completely dry and the plastic has hardened again, it may be necessary to sand the zimmerited surface in order to eliminate some hairs caused by the molten plastic.

On this base, I airbrushed the brown camo colour. In order to obtain a colour that would blend better with the base, I made a mixture with Tamiya red brown (XF-64) (70%) and the mix of dark yellow and matt yellow previously mentioned (30%) (Photo 11). Photos 12 to 15 At this stage I added the decals. The unit symbol at the rear of the turret bin came from the kit decal sheet. However from the wartime photographs I consulted it seemed too small, and the W is hollow, so I had to paint 12 its interior in white, matching with the colour of the tactical numbers on the turret sides. These are spare decals which I had and were applied using Microset and Microsol to conform to the Zimmerit. I applied a couple of filters of each of the following colours, all from the Humbrol enamel range: matt pale yellow (81), cream (103) and reddish brown (62). In all cases the paint was diluted with Humbrol thinner, which does not attack the previous acrylic paint. After this step, the model gained in chromatic variations. (slides T17-T21). Photos 16 to 17 Some chipping and scratching was made with the base colour lightened with buff (Vallejo). Also, I made some "deeper" chips with a mixture of Vallejo chocolate brown 872 and black , concentrating especially on the edges and 13 areas where a more intense wearing of the paint appears. The following step was the oil washes. As can be observed in the photographs, this technique allows obtaining a degraded and faded look on the paint at the same time the model gains once more in chromatic diversity. My method of application of the oil washes will be described with some detail and the support of step-bystep photographs in the SdKfz 251 painting chapter. Also, at this moment I painted the tracks and the tyres in black. The degraded and worn out look was then accentuated by an acrylic mapping. This technique consists of the use of very diluted paint (Vallejo acrylic) to draw small spots of 14 18 15 AFV/13 Nov/Dec 03 20/10/03 4:27 pm Page 19 irregular shape.

I tried to replicate the effect of dried mud in the recesses of the tracks and, more sparingly, on the wheels and lower hull. To make this mud, I mixed some pastel powder until I got a colour that I think was good for this purpose. Then I added to the powder a mixture of water and white glue until I obtained a paste with the desired consistency. Then, with a small brush I applied the paste to the track recesses. With a cotton bud I removed the excess paste, mainly on the outer surface of the track links. Also, I applied some patches of the paste on the wheels and lower areas and textured them with the brush. When dry I worked all the tracks and wheels with the pastel powder in order to integrate the mud. I also used some lighter shades of pastels to get some colour variations and a dried mud look. Next, I dry brushed very 27 slightly with black enamel on the outer side of the track links to “clean” the surface where the mud should have gone. At this stage I glued the side skirts and applied some pastels on them, as well as in the tools and towing cables. I painted the periscope glass with very dark green artist’s oil. I added the periscopes in the commander’s cupola made with plastic strips painted in dark green. The final touch was to apply graphite powder on the tools, towing cables, bow machine gun, anti aircraft MG rail and some handles to give them a more metallic look. Also, I painted directly on the track details and horns, and drive sprocket teeth with a soft lead pencil to achieve this metallic look. 28 The SdKfz 251 Hasegawa also has in their catalogue an extensive range of AFV’s in 1/72 scale. Some of them are older kits that date back to the 80’s or even the 70’s and are not at the same level of more recent releases. Nevertheless, some of their later kits are very close or at the same level as Revell’s best. Some of the finest Hasegawa kits are the three versions of the SdKfz 251 German half track. Hasegawa produces the “normal” personal carrier SdKfz 251/1 (ref. 31144), the SdKfz 251/22 “PakWagen” (ref. 31145), armed with a 75 mm PaK 40 gun, and the SdKfz 251/9 “Stummel” (ref. 31146), armed with a short 75 mm support gun. These last two versions are in fact the same kit as the 251/1 with the addition of a new sprue containing the gun and the corresponding attachments and a new decal sheet. The version of the famous German 28 half-track depicted in these models is the final Ausf. D, designed in order to save materials and simplify production in the second half of WWII. 21 AFV/13 Nov/Dec 03 22 21/10/03 11:33 am Page 22 29 30 31 32 33 34 35 36 AFV/13 Nov/Dec 03 21/10/03 11:33 am Page 23 Photos 26 to 29 Fortunately, this area was barely visible wide lines, “spider legs” and so on, so I The construction of the model progressed when the model was completed. had to retouch with dark yellow to finally get an acceptable result.

A generous amount of white glue diluted with water was used to fix the small stones and the tracks. To further enhance the texture of the ground, I glued bicarbonate powder as I thought that its grain size was adequate for this scale to represent the earth and sand. Also, I glued some small stones. The stone wall is also a railwaymodelling accessory. The painting process started with a first coat of Tamiya acrylic matt earth, followed by an irregular second overspray of dark yellow and a final one with buff. Then, the ground was drybrushed with several shades of Humbrol enamel ochre and tan colours. The ballast was 52 painted with a dilute Vallejo acrylic mix of white and black, changing the proportions and concentrating more on some areas than others to avoid monotony. The track sleepers were painted in a medium brown and washed with very dilute brown, ochre and grey enamels. The rails were painted in black and treated with red brown pastel and graphite powder. The stone wall was painted in grey and also treated with several washes. The vegetation comes from different sources-the short green grass is again from railway modelling. It was glued to the surface with matt varnish and once it dried, it was drybrushed with the same ochre colours as the ground to integrate it better and to eliminate its excessive green hue. The tall grasses are natural plants and some Woodland Scenic materials, as did the tree and the purple flower 53 plants. I have found that Woodland Scenic has an excellent catalogue full of very useful items for 1/72 diorama builders. The figures are from Preiser. This brand has a very comprehensive catalogue of figures at different scales, mostly intended for railway modelling but also some very interesting military items in 1/72, among them are two sets of German panzer crews. I can only say that the quality of these figures is outstanding, with very natural poses and finely sculpted details.

My reaction was like that of most beginners: Why weather anything? I felt my cars and locomotives looked quite realistic out of the box, so how could gunking them up help? I also worried that I’d ruin a perfectly good model. Why weather? “Weathering” is a catchall phrase used to describe finishing a model to duplicate the effects of time and use. Since it doesn’t actually rain, snow, or beat down with relentless desert sun on our layouts (at least I hope you don’t have those problems!) we need to resort to other materials and techniques to duplicate the ravages of Mother Nature in our plastic and plaster worlds. But don’t fall into the trap of weathering every model to the same degree. This is as bad for realism as no weathering at all. Instead, weather models to reflect various ages, maintenance practices, and locales. For example, older cars should be weathered more than newly painted cars or brand-new equipment. Automobiles in daily use may look worn but they’re rarely rusted through, especially today’s autos which feature paints designed to prevent rust and corrosion. Weathering techniques I do a lot of weathering with an airbrush but I also use washes and chalk. A wash of Polly Scale Grimy Black (9 parts Polly S airbrush thinner to 1 part paint) produces a basic road grime. Cover the entire model so the paint won’t dry spotty. Pastel chalks, available from art supply stores, are great for rust or heavy road dirt. Apply the chalk with a brush. I add more than I need, then brush away the excess. If the car looks too filthy, simply moisten your thumb and rub it along the side of the car in a vertical motion. This removes most of the chalk from the model. Combining these techniques – a wash of Grimy Black and Rust paints, followed by rust-colored chalks – makes a night and day difference between the roofs of these cars. Frequently I’ll combine all three (airbrush, wash, and chalk) on one model. The most basic weathering is eliminating the plastic sheen from models. This single step does more to increase realism than anything. Painting all your trucks and wheels flat Grimy Black also helps since it eliminates that “floating on air” look shiny trucks impart. The difference between an unweathered and weathered model is really startling, as the lead photo shows. The photos and captions explain how I used washes and powdered pastel chalks to age some N scale freight cars. The same techniques can be applied to buildings, roads, vehicles, locomotives, and even figures. Now get dirty. 1 & freight car weathering Easy ways to make rolling stock look more realistic By John Pryke • Photos by the author M any freight car weathering techniques produce a high degree of realism, but also tend to be time-consuming. If your layout has a large number of freight cars, you probably don’t want to spend an entire evening weathering just one piece of rolling stock. As an alternative, I’ve developed a quick and dirty weathering method that requires only basic airbrushing skills and a little knowledge of the prototype. Color selection There are many paints on the market made specifically for weathering. Table 1 lists the water-based acrylic and organicsolvent-based enamel paints I used to duplicate the weathering pattern shown in fig. 1. It also lists the dilution formula In September 1948, an aging New Haven 2-8-2 hauls a peddler freight toward its next destination on John Pryke’s HO scale layout. With a little prototype knowledge and an airbrush, John can apply weathering in a matter of minutes. required to spray the paint through a fine airbrush tip without clogging. Weathering color choice is also dictated by a railroad’s operating region. The color you choose to represent dirt and dust on a car’s trucks and underbody is based on the area of the country that you model or on a car’s home road. Table 2 shows some suggested truck and underbody colors for cars from different locations in North America. Quick and dirty weathering By using an airbrush with a fine tip and readily available enamel or acrylic model paints, you can weather one car in a few minutes or a batch of ten cars in less than an hour. It is important to follow each step in its proper sequence, as some prototype weathering (faded paint on side panels, soot on vertical side ribs) takes place over a long period, while other weathering (ballast dust on the underbody and accumulated Soot/exhaust: darkest in the middle, fading to light along the edges Light streaks Dark streaks Roadbed dirt/dust Rust Fig. 1 WEATHERING PATTERNS Roadbed dirt/dust: streaks above rail and on end sills and coupler soot on the roof) occurs faster and should be applied over it. I spray one color at a time on all the cars that I’m painting, then switch to the next color and repeat the process. When using a fine tip, it’s essential to keep your airbrush as clean as possible so that it doesn’t clog or spray globs of paint. While painting, I wear disposable latex gloves (available at any drug store) to protect my hands. I start by applying light streaks to the sides of the carbody, as shown in fig. 2, using a quick vertical stroke from top to bottom with my airbrush. If I am painting a rib-sided car, I spray only the panels (between the ribs) and keep the streak parallel to the ribs on either side. See fig. 3. I recommend practicing this technique on an index card or an old car shell until you are comfortable with it. Next, I paint thin, dark streaks on the ribs with a very narrow spray, again moving quickly from top to bottom. Figure 4 shows these vertical streaks on the Pennsy boxcar on the left. When the weathering on the carbody is finished, I paint the underbody and trucks with a color that matches the ballast dust and dirt from the car’s home region as shown in fig. 5. Using the same color, I also paint streaks halfway up the car’s ends above each rail. See fig. 6. These are caused by roadbed dust kicked up by the next car in a train. Control coat and soot Fig. 2 SMOOTH SIDES. For smooth-sided cars like this boxcar, John starts the weathering process by painting light streaks on the sides to simulate where dirt and grime have washed off of the roof. Next, I spray a control coat – Grimy Black diluted 50 percent with thinner – over the entire carbody. This makes a car’s lettering look dull and mutes the weathering, avoiding stark contrasts in color. The more control coat you apply the older the car will look. In fig. 4, I sprayed several passes of control coat on the car to the left; it looks like it has not seen any new paint in many years. The car on the right has only one light pass of control coat and looks like it was painted only a few months ago. Finally, I spray the roof with a dusting of soot and/or diesel exhaust, with the heaviest coating along the center line and lightest along the edges. If you model the steam era, spray Engine Black to simulate soot – especially if your layout has hills or mountains. The amount of soot on car roofs will be heavy because steam engines work hard on grades throwing up lots of cinders. Diesel exhaust is thinner, and car roofs require only a dusting of Oily Black. Optional weathering details Fig. 3 RIBBED SIDES. When spraying light streaks on rib-sided cars such as this hopper, John aims the spray between the side posts. Starting at one end, he uses a quick top-to-bottom motion to spray each car panel individually. Once a freight car has been weathered using the quick and dirty process, you can either put it in service “as is,” or add some more weathering to make it unique. • Rust: Stirrup steps, lower ladder rungs, door stops, truck springs, brake shoes, coupler faces, and end poling pockets usually display rusty spots. I hand-paint rust on these parts using a no. 5/0 brush (see fig. 7) as the last step in the weathering process. • Dust: Cars from dry climates such as the Southwest often pick up a heavy coating of dust, which settles into every nook and cranny of the carbody. I spray Floquil Dust on these cars after the basic weathering is complete, but before spraying soot on the roof. I hold my airbrush above the roofline and spray down onto the sides and ends at a narrow angle, producing the dusty car in fig. 8. • Galvanized roofs: During the transition era many boxcar roofs displayed patches of galvanized steel showing where the paint had started to peel away. I add these spots of bare metal after all of the car’s weathering is complete except for the roof soot. Using a no. 1 brush and Polly Scale Undercoat Light Gray, I paint irregularly shaped blotches on the roof TABLE 1 – Paint colors used for freight car weathering Weathering pattern: Light streaks on side panels Polly Scale (water-based acrylic): Erie-Lackawanna Gray Floquil (enamel thinned with organic solvents): Grime Weathering pattern: Dark streaks on ribs/rivets Polly Scale: Grimy Black Floquil: Grimy Black Weathering pattern: Trucks and underbody Polly Scale: see table 2 Floquil: see table 2 Weathering pattern: End streaks Polly Scale: see table 2 Floquil: see table 2 Weathering pattern: Rust Polly Scale: Rust Floquil: Rust Fig. 4 RIBS AND RIVETS.

John sprays Earth on the underframe, trucks, and lower portion of the bodies of his cars to simulate dust and dirt kicked up from the roadbed. He changes colors on cars that operate in different regions of North America as shown in table 2. Fig. 6 END STREAKS. Earth streaks over each rail on the ends of a car are caused by dirt sprayed up from the wheels of the next car in a train. Match the color used on the trucks and underframe. Fig. 7 RUST. John paints Rust onto any parts of the car that would receive a lot of wear. He added rust to the steps, ladder rungs, coupler faces, and truck parts of this boxcar with a 5/0 brush. Fig. 8 SOUTHWESTERN DUST. To create distinctive weathering on a car from the Southwest, John sprays Dust down the sides at a narrow angle from a point above the roof. The paint, like real dust, settles on all the upper surfaces of the car’s details – ribs, ladders, even the wood grain – and really makes them stand out. Fig. 9 GALVANIZED ROOF. Using a no. 1 brush, John painted patches of Undercoat Light Gray on the roof of this boxcar to simulate paint peeling off a galvanized steel roof. He then sprays Engine Black over the roof (shown on the right-hand end of the car) to represent locomotive soot. panels. I put larger blotches in the middle and only a few tiny ones, using the end of the brush’s bristles, on the end panels as shown in fig. 9. TABLE 2 – Dirt color mixes for different regions Advantages My quick and dirty weathering process consists of a few simple steps that allow you to weather freight cars in a minimum amount of time with an airbrush and readily available paints. Rolling stock weathered using this process will look great on your pike “as is,” or you can easily add some of the optional techniques to make individual cars really stand out. 1 John Pryke is a frequent contributor to the pages of MODEL RAILROADER. “Quick and dirty freight car weathering” is a follow-up to his article “Realistic weathering for steam locomotives,” featured in the August 2002 issue.

And those are just the start of the fun. It’s simple to weather your locomotives so they look more like prototype diesels, as Terry did with these F units. Read on as he shows you why real diesels weather the way they do and how you can duplicate those effects. By Terry Thompson Model photos by Jim Forbes, prototype photos by Carl Swanson O kay, let’s have a show of hands. How many of you weather your structures, and maybe even some rolling stock, but leave your diesels as squeaky clean as the day they left the factory? I thought so! What are you waiting for? I’ll confess that at one time I was reluctant to weather locomotives. “What if I want to sell it?” I thought. Then I decided that while I wasn’t sure whether I would sell any given locomotive, I was sure that my power would look better if I weathered it – and that I’d enjoy it more. Now weathering a new diesel is one of my favorite parts of the hobby. As with all rail equipment, diesels have a variety of moving parts, static parts, parts that get hot, parts that get wet, parts that are subject to the wind, and parts that are touched – often roughly. Weathering model diesels, however, is different from weathering freight cars or steam locomotives. It’s no harder, though. Even better, well- executed weathering can add so much realism that many viewers will think you’ve added extra detail to a model that’s actually out-of-the-box. In the August 2002 and February 2003 issues of MODEL RAILROADER, John Pryke showed the simple techniques he uses to weather steam locomotives and freight cars. In this article, I’ll show how you can use a few of John’s techniques plus a few that might be new to you to make your diesels more realistic. Let’s get started. 1 Sideframes Wheels can be weathered to different extents to match the rust, grease, and oxidation they exhibit on a real locomotive. The wheel on the left is unpainted, the wheel in the center is painted to simulate a new wheel, and the one on the right has been weathered with a rust color. The brand-new wheels and trucks on this SD70M shine in the sunlight, but they’re already collecting rust and dirt. You can improve even a “new” locomotive by painting wheels with a few specks of dirt. Wheels Let’s start with the wheels. Because they are not painted, they could conceivably be gray on a brand-new locomotive, but they rust almost immediately. As time passes the wheels darken from additional oxidation and a combination of dirt, brake dust, and grease. First, I clean any oil from the faces of the wheels using a cotton swab dipped in Windex. Mix an oxide red (I use one of several different Polly Scale and Tamiya colors; which color isn’t terribly important) and black of the same brand, then brush that mix onto the faces of the wheels. Don’t worry if you get some on the treads – Windex will take it off if you don’t let it dry too long. Just moisten a paper towel, lay it on some track, and run the locomotive over that. I also paint couplers with an oxide red blend, but always with an airbrush so that I don’t gum up the moving parts. Spray so the paint is nearly dry when it hits the coupler – this gives you a realistic rough finish. brush it on the inner areas. Once I love painting sideframes you’re satisfied with the results, mix because I am firmly convinced that a slightly lighter blend and paint time spent on them has a greater the pieces farthest from the rails payoff than on any other area. The (and closest to the viewer). This first step is to remove any flash or “painting for depth” parting lines and add increases the apparent detail parts. Next, relief of the part. I use decide what your an airbrush for this step base color will be. and often spray from Most railroads use below with the darker either black or silver. color and from above I don’t recommend with the lighter color. using either flat Once the paints black or straight silare thoroughly dry, ver for your base brush on a wash of because you want burnt umber oil paint to be able to mix thinned with accent colors that Turpenoid.

I don’t usually dryThough the particular brand of brush (see below) sideframes, but paint isn’t terribly important, I preit’s another option if done judifer an acrylic paint. Next, mix a ciously. That means don’t use slightly darker blend and spray or white, which is just too obvious. Rust spots and paint chips can really draw attention to the details of your sideframes. Use colors representative of the area where your locomotive works. Note the many distinct colors on the sideframes of this GP9. Carefully airbrushing dirt and grime or brushing chalk onto your model will give it this realistic look. Accenting the sideframes Some locomotives have grease near their axle bearings. Most trucks will have a light-to-heavy coating of dust and grime from the area where the locomotive works. Hint: this color should also be one of the colors you use when painting your track. I usually airbrush this from slightly above the truck using a very thin mix of the color. Chalks work well also, and they’re especially good if you want to highlight particular spots. Add interest to your trucks with accents. You will sometimes see a bit of silver on the brake cylinder piston rod. When brake shoes are changed, the paint is often chipped from bolts or other nearby surfaces, which means small rust spots appear. I just brush tiny spots of rust-colored paint onto the places where I want an accent. The lower surfaces of a truck will often develop a layer of crud. SCALE COLOR S ome modelers adjust their paint colors according to a theory called “scale color.” Here’s the short version: because air is not totally transparent, objects appear lighter in color the farther away from them we are. The smaller the scale of a model, the “farther away” we are from it visually. Thus N is farther away than O or G in scale even at the same actual distance. Great theory, but what does it mean? Simply that it doesn’t hurt to lighten all your colors a bit, especially in the smaller scales, or if your layout room is somewhat dark. – T.T. Bearing plates Many diesels have shiny bearing plates on the sides of gearboxes (“Accenting the sideframes,” page 67), which are at the center of the truck. These plates are distracting if left unpainted. Degrease them with a swab dipped in either Windex or a mix of dish soap and water. I don’t use lacquer thinner here for two reasons – it will rinse all the oil from the axle bearings, and it can damage some plastics. Dry the plates, then brush or spray them (with an airbrush – a rattle can will get paint everywhere) flat black. Notice the dirt specks, rust marks, and steel details added to the pilots. The grime-covered m.u. hoses on the bottom locomotive fit right in! Pilots Frames and tanks Not every locomotive has a visible frame, but on those that do, weather the frame with the same colors you used on the truck sideframes. I don’t spend nearly as much time on this step. All I normally do is airbrush the frame with the basic frame color then dust it with the grime color. The fuel (and water) tank, however, is a very different matter. Tanks are large and highly visible canvases for you to weather. Once again, start with the basic frame color, then add a bit of lightened frame color along the upwardfacing surfaces and darkened frame color on the downward-facing. The ends of real fuel and water tanks are literally blasted by grime, however, so make sure to put some vertical streaks of grime there, roughly in line with the wheels. Fuel will inevitably get spilled on the tank, so brush a streak of lighter (on a black tank) or darker (on a silver tank) paint under the fuel filler. (Remem- Note how the fuel tank on this SD40 has been heavily colored with grime, dust, and spilled fuel. Fuel tanks can be weathered and given extra dimension by carefully adding a lighter color to the top of the tank and a darker one to the bottom. Vertical streaks in line with the wheels will give the ends of the tank a realistic grime-blasted look. ber, you’re not seeing the actual fuel, but rather the dirt that stuck there while the surface was wet.) If your locomotive also carries water, it should be cleaner under that fill cap. And if the air reservoirs are visible over or behind the tank, weather them as you did the tank – lighter above, darker below. Ah, the pilot. So little space, so many opportunities. You’ll see stone chips, dents, and hoses that not only add color but also add their own chips in the paint. There’s also the dirt that came from any units that were ahead of your diesel, and the effects of rainwater and wind – what a beautiful thing! Most pilots start out body color. Add grime using your airbrush or chalks, and add stone chips using rust-colored paint. I will occasionally add the tiniest bit of silver in a chip, but don’t overdo it. If your locomotive has multiple-unit hoses, they should be a grimy black, with steel or rust-colored ends. If you’re feeling sporty, put some thick, dirtcolored paint in your airbrush, crank up the air pressure, and add some specks. On some airbrushes, notably Iwata and Tamiya brushes, you can also create this effect by removing the cap and nozzle from the brush before you spray. I don’t add plows, but you can accent a plow with some rustcolored paint. Rubbing a little silver Rub-n-Buff or SNJ metal powder along the very bottom can give it a just-used shine (look at a bulldozer blade to see what I mean); for a slightly less stark effect use a cotton swab to rub some graphite powder on the lower part of the plow. Fade the lettering on your locomotives by spraying with a slightly lighter version of the base color. Vary the fading by how much paint you apply. The Santa Fe F3s have a light overspray of a heavily thinned dark blue. The Baltimore & Ohio GP30 has a heavier coat of the same color. The New York Central Geep and B&O Fs have oversprays of black. The heavier rust spots on the kickplates and pilot and the more pronounced “bow wave” give the B&O F unit a more weathered appearance than the Santa Fe unit. Body sides and ends subtle. On cab units (streamlined diesels) in particular, make the grime heaviest along the bottom edge of the body. In HO or larger scales, it’s even possible to fade individual panels (or doors) by airbrushing the lighter color into the center of the panel and leaving the edges in the original (darker) color. If you go this far, you can follow up by drybrushing the model (with a brush that has had virtually all of the paint already rubbed off onto a card) with the lighter color. Doing this highlights the raised areas, like the joints between panels on an F unit, making the shadowed areas more visible. As an alternative, you can fade the model then highlight panels and doors by airbrushing a darker color around the outer edges of the panels and doors. (If you’re good enough to do this in N or Z scale, please send a photo of your work!) Several factors determine the weathering of the sides of the locomotive. The same road grime that clings to the trucks, pilot, and frame also covers the sides, though less heavily, and the ends suffer the occasional rock hit. In addition, the sun’s ultraviolet radiation causes paint to fade. So does the rain and any cleaners the railroad might use on the unit, and the minute particles of dirt that pass over the locomotive will blast the paint off over a long period of time. Depending on the locomotive, I sometimes fade the paint and the lettering. This sounds a lot harder than it is, as long as you have an airbrush. Find or mix a paint that’s slightly lighter (just slightly, though) than the body color, and make an airbrush mix that’s thinner than you would spray if you were painting the unit, but heavier (more viscous) than a wash. Spray some of it on a piece of styrene to make sure you’ll be able to lay down color without having droplets of paint visible. I often add a drop or two of Liquitex flow enhancer to the mix to make sure it covers evenly. Once you’re satisfied, spray a few light coats of the paint onto the locomotive, including the lettering. If you have the right mix, you’ll lighten the body color and (almost magically!) make the lettering look faded. Sometimes it helps to keep a new body nearby for comparison. Once you’ve faded the paint to your satisfaction, add a light layer of grime with chalks or paint. This is another point at which to keep the word “judicious” in mind. I’ve seen models over the years that were excessively weathered with Floquil Grimy Black, Dust, or both, and that’s what they look like – a model covered in paint. Remember, be By cranking up the air pressure in your airbrush, you can add dirt specks to the pilot of your diesel. Adding rust, steel, and dirt to your steps and walkways is just as easy using an airbrush or brush. Real soil will give your locomotive a more textured look. Roof – fading and exhaust Roof – fans A locomotive’s roof (page 71) will fade more severely than its sides, so make sure to fade the paint there. Diesel exhaust is a bluish black, and while it most often blows opposite to the direction of the locomotive’s travel, most power will eventually have a bit of it on nearly every part of the roof. Simulate it with a flat black, with a bit of very dark blue added if you like. On a black locomotive, it’s doubly important to fade the paint, because otherwise you won’t be able to see the exhaust residue! The fans on a model diesel are very visible. On some diesels, I’ll airbrush the tops black and then drybrush with body color to bring back the grill detail, and on others I’ll leave the fans body colored and use a wash to increase the apparent depth. Some model railroaders like to highlight fan blades with silver or steel so that they’re especially visible. I can’t get too excited about that, though, because an operating locomotive would have its fans running, making the blades a blur. Footboards, steps, walkways, and doors These areas attract not only road grime but also whatever the crew members might track onto them. They also get scuffed and chipped, which means that you’ll see bare metal and then rust. Add grime with your airbrush or chalks, then accent with rust, steel, and dirt. For a nice textured effect, sprinkle just a bit of real soil over wet dirt-colored paint. On steps, the outer and center parts of the tread are the most likely areas to have the paint worn off and the areas most likely to remain free of rust. Kick plates and doors get similar treatment, and handrails will likewise have chips, wear, and areas polished smooth.

Box 292713 Sacramento, CA 95829 Polly Scale Acrylic paints in railroad and military colors Turpenoid Paint thinner available at craft stores This C&NW GP15-1 has an especially weather-beaten appearance because of its use in drag-freight operations around heavy industries. Special effects Senior editor Carl Swanson noted that how a locomotive weathers is especially dependent on three factors: geography, service, and age. For example, the trucks and frames of locomotives that serve in mountainous territory will often have a dusty appearance from the sand that they use to get traction, but their bodies are often blackened from being in smoky tunnels (Southern Pacific fans know what I mean!). Locomotives that work in iron ore country (or in steel mills) will often have a reddish appearance. Locomotives in heavy service, like drag freight operation or pusher service, will often have a more weatherbeaten appearance than a locomotive in passenger or intermodal service. And don’t forget to consider a locomotive’s age – a GP9 would likely look considerably different by the 1970s than it did in the ’50s. (If you’re really getting specific, consider whether the period you’re modeling is toward the beginning or end of a particular paint scheme’s time frame.) I admit that I sometimes get a little carried away with weathering, but if you look at the prototype (and you don’t even have to look very closely), you’ll see that locomotives are dirty pieces of machinery. There is a point in weathering beyond which you can overdo it, but with practice you’ll develop an eye for what looks right. Roof – heat The roof is also where heat affects a locomotive’s paint most severely. The exhaust stack(s) will have no paint on their sides – paint them rust, with black at the very top and a transition to body color at the bottom. The dynamic brake grids will often lose their paint in the same way. A light coating of rust, or even shades of rust with some heat discoloration (bluish color) in the center, will accent them. If your locomotive has a steam generator, don’t forget to show the effects of heat in that area also. Even if you didn’t overspray your locomotive with body color to fade the lettering, a coat of a lightened version of the body color will help imitate the fading that comes from the sun’s rays. On darker locomotives it also allows the exhaust stains to be visible. On my NYC diesels, I always lighten the roofs, even if the locomotive is otherwise quite clean. If you really want to see the details, drybrush with an even lighter color. Notice the different levels of weathering on the roofs of these three locomotives. The B&O F7 (top) was weathered extensively, with fading, exhaust, and heat damage evident on both the roof and fans. The B&O GP30 wears a slightly less weather-beaten look, while the ATSF F3 has black only around the fan and stacks. TIPS FOR HAPPY AIRBRUSHING • Never shake paint – always stir. Shaking leaves paint around the top of the jar, where it dries into clumps. Those clumps are the best way to clog an airbrush. Using a screen on your pickup tube can help, as can straining your paint before spraying. • Stir thoroughly. It takes longer than you would think to remix a bottle of paint that has settled, especially if a large percentage of its pigment is clay (common on tans, grays, and browns). • If using a single-action brush, close it (run the needle forward or twist the tip closed) if it will sit for more than 20 seconds. Thinned paint dries quickly. • Drain your water trap each time you spray. It can’t work if it’s full. • Make sure your thinner is clean. Dirt or lint (been doing the old tip the can onto the towel trick?) can clog your brush, or at least appear in your paint. • Lubricate your airbrush according to the instructions, and don’t abuse it by over-tightening the threads. • Some parts, including washers, gaskets, needles and tips, will wear out. Paint is abrasive (due to the pigment – many contain titanium dioxide), and solvents are harsh chemicals. Keep spares so you can keep modeling. • If you think you bent your airbrush’s needle, check it by pulling it across a towel while rotating the needle. Do not check it by running it back into the brush – that just ensures that you’ll ruin the tip or your airbrush as well. • If you own needle and tip sets in multiple sizes, keep the sets separate. They all look very similar, but they don’t all work together. • If you can afford to, it’s a good idea to have separate airbrushes for solventbased paints and acrylic paints. The two paint types don’t mix well, and sometimes paint left in an airbrush can form clots when exposed to a solvent. • When you reassemble a double-action brush, the action should be crisp. If the needle sticks in the nozzle or the action seems mushy, there’s still paint in the nozzle. Clean it again. • If you get bubbles in your color cup or feed jar, you have an air leak, probably where the tip joins the nozzle. Check your brush’s instructions to see whether you can repair it. • Weathering mixes are much thinner than regular airbrush mixes, so their pigments settle faster. Remember to stir every few minutes. • Flow enhancer can help substantially when spraying acrylics – a few drops per jar of weathering mix is plenty. • Lower your air pressure when spraying thinned mixes of solvent based paints to avoid spidering. You can spray from surprisingly close to a model with low pressure, well-thinned paint, and an airbrush with a small aperture (I use an Iwata brush with an .18mm tip for really fussy work). Removing the cap (or installing a crown cap, if available) can let you get even closer because the blowback can dissipate more easily, but be careful – once the cap is off, your needle has no protection. • Most manufacturers have a recommended airbrush mix, but consider that a starting point only. Different colors (even different bottles of paint) will behave differently. Mix, then test, then adjust if necessary before you start painting your model. • Test your mix on a similar substrate – if the model is styrene, test on styrene, and so on. - T.T.

In fact, some lineside buildings and pieces of railroad equipment have more bare wood or rusted steel on them than their original paint and primer. You can easily learn several tricks that will allow you to achieve the weathered look of the prototype on your own models. The key is to develop an eye for color. Look closely at any piece of landscape art, and you’ll see that the artist used many different colors to achieve what at a distance appears to be a solid color. This same principle holds true in real life. Almost nothing in the real world is only one color, but instead a combination of distinct separate hues when observed closely. Even shadows add their own color to the surface. The blend of color that makes up what we see in the real world, particularly on structures that have suffered the effects of nature, can be reproduced in our modeled world using various commercially available art and office supplies and easy-to-make stains. Fol- Steve Harris built this American Model Builders’ Baltimore & Ohio depot kit straight from the box, but aged the model using a number of weathering techniques. Follow along as he explains how to make structures look as though they have withstood the ravages of time. lowing are some of the methods I’ve used to mimic the effects of age and the elements on my own models. With some practice and careful observation of real structures, you should be able to give your models a greater touch of realism too. 1 Steve Harris lives with his wife in Valley Center, Calif., a suburb of San Diego. He models the Rio Grande Southern in HOn3 and built his layout in an office trailer. Steve’s modeling work has also been featured in the Narrow Gauge & Short Line Gazette. Powdered pastels I like to use powdered pastels and pigments to get a soft-edged color application that looks to me more natural than if painted with a brush or airbrush. To cover a broad area, simply brush the pastel powder on the model. For more control in a small area, or to scrub the powder into the surface, use a Microbrush disposable applicator. A little pastel powder goes a long way, so be sure to practice before you apply it to your model. When you have the color where you want it, fix it in place by applying a light coat of Testor’s Dullcote. Because the Dullcote tends to make the coat of weathering less apparent, you may need to apply more pastel powder and Dullcote. I make my weathering powders by rubbing colored pastel sticks on a piece of drywall sanding screen mounted on two wood blocks as shown in the photo. I place a sheet of paper under the mesh to catch the powder (a fold down the middle will help you dump it). Sometimes I grind up several colors and mix them to get the shade I want. I save these mixtures in a plastic parts box for future use. I also use Bragdon Enterprises weathering powders (pre-ground) which seem to affix themselves to surfaces a little better. Using alcohol-based stains Isopropyl alcohol is a good medium for making your own stains by adding India ink or shoe dye for pigments. I use alcohol instead of water because it penetrates well, dries fast, and is less likely to warp wood. Isopropyl alcohol is also inexpensive and available at any drugstore. Get the highest percent alcohol you can find, as it contains less water. I use leftover film cans to mix and store my dyes and stains, labeling the cans to show the formula I used. Start by filling the film can nearly full with alcohol, then use an eyedropper to add ink or shoe dye. As the brew darkens, test it on a piece of scrap material and add drops of ink or dye as necessary. A comparison of shoe dye and ink stain on scribed wood siding is shown in the top photo. Alcohol and India ink stain applied to wood gives it a weathered gray look as if it had been out in the sun for many years. I use it for things like station platforms and loading docks. Alcohol and shoe dye gives wood a darker, creosoted appearance. It works well on things like ties, trestles, and timber cribbing, as seen in the second photo. Any shoe dye will work, as long as it does not produce a shiny finish. I use a mixture of half brown and half black dye. Pastel pencils Pastel pencils allow you to quickly and precisely apply color to areas that are too small for powdered pastels. These are great for coloring individual boards on plank, scribed, or clapboard siding as well as door and window trim. For a weathered wood-siding look, I use several different colors, being careful not to overlap the edges of the boards. I use two or three shades of gray, a couple of browns, and sometimes a little black. I blend the colors by rubbing them with a blending stump, which looks like a crayon made from rolled up paper, though a piece of thick cardstock cut to a sharp point works just as well. To get an evenmore-blended look or to bleed the colors, rub it with a little alcohol. On the building at right, I first stained the individual boards using the alcohol-and-dye technique, then weathered the wood with the pastel pencils. I used a white pencil to add the remnants of paint in the protected area under the eaves, then blended the color into the unpainted area with a blending stump. I also use pastel pencils on my wood-sided rolling stock to tone down the white lettering, as shown on the boxcar above. Drybrushing Artists often lighten the tips of objects to simulate the reflection of the sun. I accomplish the same effect on my models by using the drybrushing technique. Drybrushing is just what it sounds like. For a broad area like a roof, use a wide, flat brush and wipe off most of the paint on a piece of cardstock or paper towel until the paint is streaky. Then lightly whisk it over the area you want to highlight. For example, on the Rico station roof above, I first stained the roof with shoe dye and let it dry. Then, I drybrushed thinned white paint on the roof to highlight just the tips of the shingles. Etched corrugated roofing After many years of exposure to the elements, corrugated metal siding and roofing begins to rust, leaving jagged, decayed edges. Dipping model panels in etchant can produce this same look. Because of its harmful effects, make sure you use etchant in a well-ventilated area, according to the manufacturer’s Scratching back Use this technique on styrene siding to simulate wood or to make a painted wall look worn. First spray the model with two or more coats of the undercoat paint. Then after each coat has dried thoroughly, lightly “scratch back” through the painted surface with a scratch brush (a fine wire brush) or fine sandpaper to expose the undercoat. Be careful, because it’s easy to scratch too instructions, and wear proper eye and skin protection. First, cut sections of metal corrugated material into the sizes you’re going to use on your structure. Pour a little etchant into a plastic container, then drop a panel into the etchant. After a few seconds, the panel will begun to bubble indicating that the etchant is starting to work. After a few more seconds, lift out the panel with a pair of tweezers, rinse it thoroughly in cold water to stop the etching process, and lay it out to dry on a paper towel. The resulting panels are fragile, so handle them carefully. In addition to eating away some of the metal, the etchant also conveniently discolors them with a blotchy weathered look. If you had a different color in mind, spray paint or dust them with pastels. I used this technique on some of the panels on my model of the Ophir tram house. Before assembling the structure, I painted the panels, including the etched ones, different shades of Floquil brown. I then used pastel powders to give them the final rusty touch. much and expose the white styrene. I used the scratch-back technique on my model of the Ophir depot. First I sprayed the styrene walls with a mixture of Floquil Roof Brown and white and let the first coat dry completely. Next, I sprayed the walls with Floquil Depot Buff. Then, using a folded piece of fine sandpaper, I lightly scratched the buff coat back to the first coat to get the look of worn paint. TIPS FOR BETTER RESULTS • Whenever possible, use a photo of the prototype you are modeling as your guide. It is much easier to catch details held in photographs of the real thing than trying to work from memory. • Before using any weathering technique, test it on a piece of scrap material. This will give you a preview of the final look and help avoid nasty surprises. Also, with a little experimentation, you may even find a better approach. • Plan ahead and weather your model as early in the building stage as possible. Though some techniques can be applied to the finished model, many, such as scratched or peeling paint, must be done before assembly. It’s also easier to work on a wall when it’s flat on your workbench. • Doors and windows show the effects of the weather too, so remember to make your trim pieces appear as tired as your walls. • Be prepared to do it again. Mistakes will happen and sometimes the only way to master a technique is to be willing to try again. – S. H. WEATHERING A BALTIMORE & OHIO DEPOT Exposed roof sections weathered with alcohol and ink stain Correction film paint I use correction film to simulate peeling paint. To start, I stain the siding with the color I want to show through the peeled paint. I then place correction film over the surface and burnish it with a burnishing tool or ball-point pen just like when using a dry transfer. The technique transfers some, but not all, of the white material to the wall, leaving lots of places where the “paint” has peeled away. If you want more of a peeling effect, use a scratch brush to expose more of the undercoat.

I treated it as if the depot hadn’t seen any paint or other maintenance for many years. That gave me the opportunity to employ a number of my favorite techniques. I started with the walls. Time and weather fade paint and turn exposed wood a silver gray. Before removing the sides from their material sheets, I stained them with a base coat of alcohol and ink. The stain accentuated the seams between the boards and gave the walls the correct weatheredgray look. Next, I made a custom paint mix for the station using 10 parts Floquil Reefer White, 1 part Reefer Yellow, 10 parts Depot Buff, and 2 parts thinner. (Always start with the lightest color and slowly add the others to it.) The result was a thin, faded version of the original buff color. (Before adding most of the white and the thinner, I painted the underside of the overhanging roof, which would still be closer to the original color as it had not been exposed to weather.) I drybrushed the paint over the gray walls, keeping in mind that each board would have weathered in a manner slightly different from its neighbor. With thinned paint I could build up the final color in successive coats, providing variety. Finally, I used three different colors of gray pastel pencils lightly drawn over individual boards. I made the broken windows by cutting clear styrene with a no. 11 hobbyknife blade and a little patience. My goal was to make each window a little different from the others – some are Paper signs weathered with brown shoe dye stain Glazing dusted with pastel powder to look dirty missing entire panes, some have a few shards remaining, others are simply cracked. After installing the glazing, I dusted it with powdered pastels to make the glass look dirty. I wanted some of the bare sub-roof to show through the shingles, so in several places I scribed the roof panels to represent planking and then gave them a wash of ink stain. The slate roof material comes in precut strips with peel-and-stick backing. I sprayed it with Floquil Southern Pacific Lark Dark Gray, then lightly airbrushed over that coat with Reefer Gray and SP Lettering Light Gray. Unfortunately, the solvent in the paint caused the adhesive to come off the shingles. As a result, I had to glue the strips on one at a time. A water-based paint would work better. I painted the trim Roof Brown. After gluing the trim in place, I weathered it with a gray pastel pencil. I made the depot signs on my computer, printing them in color on glossy paper and then fading the lettering with a wash of white acrylic paint. I also lightly weathered the signs with a wash of thinned shoe dye stain. Once I had glued them in place, the depot was complete – another model made to look as though it had been ravaged by the effects of nature and time. – S. H. Painting and weathering track PHOTOS BY JEFF WILSON O ften we pay so much attention to painting and weathering locomotives and freight cars that we forget the track they run on is worthy of similar attention. Today’s ready-to-use track generally has fine detail, including close-to-scale tie plates and spike heads, accurate rail profile, and wood grain molded into the plastic ties. However, the bright nickelsilver rail and shiny plastic ties detract from the appearance. A little time and paint can easily take care of this. You can take painting track to as high a degree of detail as you want. Simply painting the ties and rail a uniform shade of flat brown is an improvement. You can go on to paint and weather the rail, individual ties, and even spikes and tie plates. Preparation Painting track after it’s laid lets you get it working properly, with all feeder wires and gaps in place, before painting. If you do this, paint the track before adding scenery. Should you have to paint track in a scenicked area, use masking tape and paper to protect the scenery from overspray. A disadvantage of painting track in place is that it can be awkward to get an airbrush into tight areas. Using solvent-based paint or spray cans is also a hazard in an enclosed room. Track appearance is important, but not as vital as locomotive electrical contact. For good contact it’s important to ensure that you can easily remove paint from the railheads. One way to do this is by applying a light coat of oil to the railheads before painting. Once the rail is painted a Bright Boy or similar track cleaner will easily remove the paint. Figure 2 shows how to apply the oil with a cloth. It doesn’t take much – just wrap a corner of a rag around a fingertip and rub the cloth along the railhead, taking care not to get oil on the ties or sides of the rails. Turnouts require special care to avoid gumming up the moving parts with paint. Before painting, mask along the points and throw bar as shown in fig. 3. Brush-paint these areas later. You’ll also have to clean paint from the rail before soldering feeder wires and from the rail ends before adding rail joiners. Consider the colors you want to use. Wood ties on a heavily used main line are replaced often, thus are usually black You can paint track before or after it’s installed on a layout. The advantages of prepainting track are that you can do it in a spray booth or outdoors without worrying about paint fumes or getting stray paint on your layout or scenery. One disadvantage of prepainting flextrack is that the plastic spike heads mask the rail, and as you bend the track some of the spikes move, revealing shiny areas that were shielded from the paint. See fig. 1. Simply touch up these areas with a brush. Fig. 1 SPIKE MASKS. When prepainting flextrack the spikes sometimes move, revealing unpainted rail. Touch these up with a brush. Fig. 2 OILING RAILHEAD. Applying a light coat of oil with a piece of soft cloth makes it easier to remove the paint later. With a few simple techniques and some paint, you can turn shiny nickel-silver track into a near replica of the real thing. Fig. 3 TURNOUTS. You can airbrush turnouts as you do flextrack, but mask the points and throw bar and paint these areas by hand. Fig. 4 COMPARISON. Simply painting flextrack a uniform shade of brown is an improvement compared to unpainted flextrack. Fig. 8 TIES. Give individual ties washes of black, gray, grimy black, and brown. The grayer a tie is, generally the older it is. Fig. 5 PAINTING RAILS.

Painting the roadbed, rails, and ties greatly improved the appearance of this Life-Like True-Track. Fig. 7 PAINTING ROADBED. Give the roadbed a wash of Grimy Black or any medium gray to black color to cover the plastic appearance. or dark brown and are uniformly spaced. Spurs and lightly traveled branch lines often have older ties that have weathered to medium or light gray, with much more variation in color and spacing. Rail can be found in many shades of dark brown and dark rust while spurs, sidings, and branch lines sometimes have a brighter rust color. The next step is to highlight the rails with streaks of lighter colors. An airbrush is handy for finer control, but you can use spray cans if you’re careful. Aim directly from the sides, just hitting the outside of the rail nearest you and the inside of the far rail. You can also do this step with a brush, but it will take a bit of time. See fig. 5. Don’t worry if a little paint gets on the ties. Painting Combination track and roadbed Start by painting the ties and rail a dark brown color. If you have an airbrush you can use any flat dark brown, such as Polly Scale Railroad Tie Brown, Roof Brown, or Rail Brown, or mixtures of all. Spray cans also do the job in short order. For the samples shown here I used Krylon spray paints including nos. 8142 Brown, 8147 Medium Brown, and 1317 Ruddy Brown Primer. Cover the ties and rails from all angles, making sure the paint coats the sides of the rails. Figure 4 shows a strip of flextrack after painting. As fig. 6 shows, painting greatly improves the appearance of combination track and roadbed. Start by separating the track and roadbed if possible, then paint the track in the normal way. Figure 7 shows how I gave the roadbed a wash of Polly Scale Grimy Black (one part paint, ten parts Polly S Airbrush Thinner). You can use other colors as well. Once they’re dry, press the pieces back together. If you’re working with track that can’t be separated, brush-paint the rails, give the roadbed a wash, and paint the ties individually. You can stop at this point and have nice-looking track, but for a truly outstanding appearance you’ll need to break out a fine brush and highlight the details. Paint individual ties with washes of grays, browns, and blacks for a varied appearance. See fig. 8. These highlights should be subtle on mainline track, with more variations on lightly used track. I keep four mixes handy: black, grimy black, gray, and Railroad Tie Brown. Go ahead and dip your brush in more than one mix to create varied effects. Well-used track often has a blackish streak down the middle created by grease and oil dripping from locomotives and cars. Re-create this effect with Polly Scale Oily Black paint as fig. 9 shows. If you really want to take your track to another level, get out a fine-point brush and some rust-colored paint and highlight the tie plates and spike heads. Although this often isn’t practical for an entire layout, it adds fine detail to foreground scenes. When you’re finished, use an abrasive track cleaner to gently polish the railheads, and you’re ready for trains. None of these techniques are difficult, and a bit of time and paint are all it takes to turn ordinary track into a worthy stage for your detailed locomotives and cars. 1 Jeff Wilson is a former associate editor for MODEL RAILROADER. PRODUCTS I N F O R M AT I O N S TAT I O N Basic electricity and control systems Electricity K nowing how to use electricity in model railroading extends beyond running trains. You’ll also want to use electricity to power switch machines, structure lights, streetlights, and other accessories. Having a good basic knowledge of electricity will help you use these accessories with confidence and improve the realism (and fun) of your layout. Let’s start with some basics. Fig. 2 POWER PACK CONNECTIONS. MRC’s Tech II has fixed DC terminals for accessories. Power packs also include variable DC (track power) and fixed AC (accessory) terminals. When making connections, always wrap wire clockwise around the terminal screws. PHOTOS BY JEFF WILSON To trains or accessories AC vs. DC 3 Standard house current is alternating current(AC), and although some model trains (notably three-rail O gauge, American Flyer S gauge, and Märklin HO) use AC, most scale model trains use direct current (DC). With AC, as the name implies, the polarity constantly alternates at 60 cycles per second in the United States. With DC the polarity is constant as the current flows. Direct current allows us to use polarity to control motor direction (very important in running trains), something that can’t be done with AC. Figure 1 shows how this works. On a typical power pack, the variable DC output goes to the track – this is what is adjusted by the speed controller. Most power packs also have fixed AC terminals, and some also have fixed DC terminals (see fig. 2), which put out continuous voltage. These can be used for accessories. Power supply 3 Ammeter 12 0 12 Voltmete r Ammeter connected in series Voltmeter connected in parallel Volts and amperes It’s important to provide the proper voltage to accessories, as too much power can burn out bulbs and motors. Electricity is measured using volts (V) and amperes (A). I find it easiest to understand each using the analogy of a water supply pipe coming into your house. Volts measure the force of electricity (the pressure gauge on a water pipe) and amps measure the amount of electricity (the water meter). The water pressure (volts) to your house remains constant, but the volume of water (amps) used varies depending upon how many faucets you have open at a time. The electricity in your house is at 120V, much too high to use safely Direction of travel Motor Motor Polarity Polarity Fig. 1 DC POLARITY Direction of travel 0 ILLUSTRATIONS BY ROBERT WEGNER Fig. 3 METER CONNECTIONS for model railroads. Transformers reduce the voltage to the 12 to 18V needed for trains and accessories. For current, most modern locomotives in HO and N scales use less than .5A, while some older models draw more. Engines in O scale and larger models can use 1A or more. Small devices such as light bulbs require little current, and their current consumption is often measured in milliamps (mA). For reference, one milliamp is a hundredth of an amp (1mA is .01A; 5mA is .05A). Most power packs and other power supplies are rated in volt-amps (VA), meaning “volts x amps.” To convert this to the ampere ratings used by model railroaders, divide the output rating of the power pack by 12, which will give you the pack’s amp output rating at 12 volts. Light bulbs are probably the most commonly used electrical accessories. Most small bulbs draw roughly 10mA (0.1A), while some microbulbs draw less than 5mA. How do you know if there’s enough power for all of your accessories? Add the current required for all accessories and make sure the total is less than the rated limit of your power supply. For example, if you have a 1A power supply Each bulb receives full voltage 12V 12V 12V Optional switch To other lights 12V 4V 4V Parallel 4V Single-pole, single-throw (SPST) Optional switch 12V Series Voltage is divided among bulbs Fig. 4 TYPES OF CIRCUITS you can use it to power ten 10mA bulbs or 20 5mA bulbs. You can determine the amount of current a bulb or accessory is drawing and how much voltage is in a circuit with separate meters or a combination volt-ohm-milliammeter (VOM) as shown in the photo on page 54. The proper way to connect a voltmeter and ammeter in a circuit is shown in fig. 3. Don’t use a VOM as part of a permanent circuit, as the electronic components of the milliammeter function can be damaged by continuous use. It’s a good idea to have a separate power supply for accessories. With small power packs, the drain of accessories can slow your trains, and increasing the speed of trains can dim your accessory lights. It’s also good practice to operate bulbs at less than their rated voltage (12V for a 15V bulb; 1.2 or 1.3V for a 1.5V bulb). This increases bulb life and lowers the operating temperature, important with plastic models. Series and parallel You can connect multiple accessories or bulbs in one of two ways: series or parallel. Figure 4 shows each style, using light bulbs as an example. Parallel connecting gives each bulb the same voltage, regardless of how many there are. Adding bulbs is easy by wiring them to the main (bus) wires. Connecting in series (end-to-end) divides the voltage equally among all bulbs. A disadvantage is that if one bulb burns out, the whole string loses power. Throwing switch turns power on or off Single-pole, double-throw (SPDT) Throwing switch directs power to one of two circuits Fig. 5 TOGGLE SWITCHES Also, you can’t add additional bulbs while keeping constant voltage. Switches You can turn accessories on and off by turning the power supply on and off, but a better way is with a switch. Figure 5 shows the two styles of toggle switches used on most layouts. They come in a variety of sizes and styles, with the single-pole, singlethrow the simplest type (a basic on-off switch). The number of poles refers to the number of connections that can be made. The number of throws is the number of positions that the switch can be turned to.

The more comfortable you are with wiring, the more animation and life you’ll be able to bring to your layout. 1 Cab control Insulated joiner (or gap) switch which can turn the power to that block off. Since the switch is a doublethrow type it connects only one of the cabs to the block at any one time. The illustration at left shows how to connect both cabs and a switch to a single block. Of course, you need more than one block on the layout. The schematic drawing shows how to wire an oval with a passing siding for two-train control. The wiring may look complex but it’s simply a matter of repeating the single block wiring as necessary. You’ll need not only a cab but also as many single-pole, double-throw (SPDT) switches as you have blocks. Another option is the Atlas Selector, which is simply four SPDT slide switches in a single case. Most modelers, though, prefer to have the switch controlling a particular block mounted on the control panel schematic, making it easier to tell at a glance which block a switch controls. It’s a good idea to test each block as you wire it up as crossed wires are the biggest problem with cab control. And be sure you color code your wiring as it makes the initial wiring and any future alterations or troubleshooting a whole lot easier.

Getting a single train to run around the layout is usually a matter of simply running a pair of wires between the power pack and the track. But simply placing a second locomotive on the track will mean both trains run in the same direction at the same relative speed, so getting independent control of two trains will require some additional wiring, what we commonly call cab control. Cab B Layout wiring Cab control works by dividing the layout into electrically isolated sections of track, called “blocks.” You can do this using plastic insulating rail joiners or by cutting a gap in the rails and filling it with a non-conductive material like styrene. Since you can isolate the track sections by gapping only one rail, the other rail is called the common and is wired to both cabs. Power wires, or feeders, from each block are connected to an electrical How it works Once your wiring is complete place one locomotive in block 1 and flip the toggle for that block to cab A. Then place a second locomotive in a different block and flip that toggle to cab B. You should be able to control the two locomotives independently within the individual blocks. As the trains work their way around the layout turn the next block to the appropriate cab. Turn off the block after you leave it or the next train entering the block will be controlled by the “wrong” cab, leading to that familiar cry of “Someone’s got my train!” While command control (another topic for a later time) takes care of that problem, cab control is still a viable option. For more details on layout wiring see Easy Model Railroad Wiring by Andy Sperandeo (Kalmbach Publishing Co.), which includes a detailed explanation of cab control and the associated wiring. 1 Wiring reverse loops Fig. 2 LOOP SHORT CIRCUITS Short circuit! Return loop with all-live turnout Short circuit! Return loop with power-routing turnout PHOTO BY JIM FORBES R everse loops – tracks that turn trains around – can add a great deal of operating interest to a layout, but they also require special wiring that goes beyond connecting a pair of wires to the track. Some modelers avoid building layouts that have a return loop or wye, thinking that the wiring is beyond their level of expertise. However, there’s no need to fear. Although reverse loops require special wiring, the job is not difficult and can be done quickly. What qualifies as a reversing track section? The most common is the simple return loop or “balloon track,” but wyes and reversing cutoff tracks also qualify as reversing sections and need special wiring. Figure 1 shows four examples. In some track plans the existence of a return loop isn’t as obvious. To check Without special wiring, turning trains on loops or wyes on your model railroad will cause an electrical short. Fortunately, wiring a reversing section of track is easy. You need only a little electrical know how, some wire, and a toggle switch or two. a plan, trace the path of a train around various routes. If a train can wind back to go the opposite direction on a track without reversing the locomotive, then there’s a reverse loop. Without special wiring, a reverse loop will result in a short circuit as fig. 2 shows. This is true regardless of whether you’re using a single power pack, a cab-control system with multiple power packs, or Digital Command Control [For more on reverse loops and DCC, see DCC Corner in the August 2003 issue of MODEL RAILROADER Fig. 1 TYPES OF REVERSING TRACKS Return loop or “balloon track” Cutoff track Magazine. – Ed.], and whether your turnouts are either the all-live or powerrouting type. The basic idea in wiring a reverse loop is to isolate the loop itself using insulated rail joiners to make it a separate electrical block. Double-pole, double-throw (DPDT) switches are then used to change the polarity of the loop track, thus avoiding a short circuit. There are two simple methods of wiring loops: One method uses a single DPDT switch; the other uses two switches. Reversing with one switch Figure 3 shows the single-switch method. It’s the simplest to wire; however, it can be difficult to operate smoothly without bringing the train to a complete stop. Here’s how the single switch works: First set the loop direction switch to match the polarity of the main line, allowing the train to enter the loop. Next, stop the train on the isolated section of track and throw the power pack’s reversing switch, the loop switch, and set the loop’s turnout to Fig. 3 SINGLE-SWITCH METHOD Turnout set for diverging route Wye Loop direction DPDT switch Figure-eight connector Power pack ILLUSTRATIONS BY RICK JOHNSON allow the train to exit the loop segment back onto the main line. You can try using this method without stopping the train by throwing both the reversing switch and the loop switch at the same time, though it can cause jerky operation. Reversing with two switches The better method for layouts with standard DC control is to use two DPDT switches, requiring only a bit more wiring, as shown in fig. 4. The additional switch serves as the mainline direction switch. It lets you change the polarity of the main line independent of the reversing section, eliminating the need for stopping the train (or throwing both switches at once) while the train is in the loop. A potential problem is that it’s impossible with toggle switches alone Fig. 4 TWO-SWITCH METHOD Turnout set for straight route Mainline direction DPDT switch Loop direction DPDT switch Power pack Fig. 5 ADDING POLARITY INDICATOR LIGHTS Optional red bulb to indicate polarity doesn’t match 16-volt light bulbs Green bulb lights when polarity is correct for route for an operator to determine for which route the polarity is aligned. A simple solution is to use a pair of green 16-volt bulbs wired as fig. 5 shows. Place them on the control panel next to their corresponding routes. Whichever is lighted indicates the correct route. Another option shown in fig. 5 adds a red bulb to indicate incorrect polarity. These aren’t necessary if you’re using green bulbs set in a control panel, but you can add a bit of animation to the layout by using both red and green lamps in lineside signals to show operators if the track polarity is correct. You can also control return loops automatically, but that’s a bit beyond this column. For a thorough look at return loops, including details on wiring wyes and incorporating return loops with cab control wiring, see Andy Sperandeo’s book Easy Model Railroad Wiring, Second Edition (published by Kalmbach). 1 Basics of wire O nce you begin building a layout you quickly discover you need a lot of wire. Control panels, track feeders, switch machines, lighting, signals, and other accessories will require separate circuits. Knowing what different types of wire can do, what tools and connectors are available, and what connection options you have besides solder can help you wire your layout more quickly and easily. Work toward two goals when wiring: First, ensure that every circuit never has a reason to fail. Crawling under a layout to find a broken wire doesn’t fit my goal of model railroading being fun. Second, Fig. 2 TOOLS. Small and large (6" and 8") wire cutters and a combination wire stripper/crimper are vital for working with wire. organize and label circuits to make later modifications or troubleshooting easier. Wire Fig. 1 WIRE. Many types and sizes of wire are available. Shown here are 14-gauge solid, 18-gauge stranded, 22-gauge solid, and twoconductor 24-gauge solid (speaker wire). Insulated copper wire (fig. 1) is the standard for electrical wiring. Wire has two key descriptors: gauge (size) and whether it’s stranded or solid. The size is measured in gauge and indicated by a number, as in 22AWG (American Wire Gauge) or 14AWG. The smaller the number, the larger (in diameter) the wire. The larger the wire, the more current it can handle. Most 120V (volt) household wiring is 12- and 14-gauge wire. Either will work well for track and other main power supply wires on model railroads. Smaller wire, such as 20 or 22 gauge, is okay for track feeders, but shouldn’t be used for long runs, because the voltage will drop more the farther the wire is from the power source compared to heavier wire. Solid wire should be the first preference for most applications. It’s easy to strip and prepare for soldering and Fig. 3 SOLDERING IRON. A 30-watt penciltype iron with stand and rosin-core solder will handle most soldering jobs. Fig. 4 COMMON JOINTS. For a T-shaped joint, wrap the feeder wire around the main wire. For splices, wrap the wires around each other. can be used with crimp-on terminals. Use stranded wire where flexibility is important. You can find smaller sizes of wire at electronics stores such as Radio Shack as well as many hobby shops. For heavier wire, check hardware stores or home improvement centers. Heavy wire can be purchased either by the foot or in spools of 100 to 500 feet. Wire cutters and strippers Several tools are handy – make that necessary – for working with wire. A good pair of cutters like those in fig. 2 will stay sharp for a long time, but never use them to cut piano wire or other steel wire or the cutting edge will be damaged. A wire stripper is indispensible. See fig. 2. Many modelers try to get by without one, but the first time you use a good wire stripper you’ll wonder why you wasted so much time whittling insulation with a knife. Wire strippers make an otherwise tedious job fast and easy. Crimping tools enable you to use many types of wire connectors. Many strippers are combined with a crimping tool, such as the one in fig. 2. now many lead-free solders available. Never use acid-core solder for wiring, as electricity flowing through the joint will cause corrosion. Figure 4 shows two of the most common solder joints. Whichever joint you use, the technique is the same. Place the iron at the joint as in fig. 5. Once the joint – “work” – is hot, touch the solder to the work – not to the iron – until the solder flows freely through it. Remove the iron and keep the work still until the solder sets. A good solder joint should be shiny. The solder should flow around all of the wires with no clumping. See fig. 6. If the work moves while the solder is still liquid, the solder will appear crystallized and the joint won’t be solid. If this happens, reheat the work until the solder flows again. Be sure to cover all solder joints. Leaving them exposed is an invitation to a short circuit or other problem. The best way to do this is with heat-shrink insulation tubing. Figure 7 shows how to do this. Thread a length of tubing onto the wire before soldering the joint. Once the joint is made, slide the tubing into place. Rub the side of a soldering iron (not the tip) against the tubing and it will shrink tightly around the wire. You can also use vinyl electrical tape to protect joints, but this tape has a habit of unraveling over time. Spade and other connectors Whenever a wire needs to be connected to a screw terminal (such as on a power pack or terminal strip) you can add a spade connector as in fig. 8. Strip the end of the wire, ensuring none of the bare wire will be exposed beyond the connector. Slip the spade into place, then use a crimping tool to fasten it. Figure 9 shows a couple of other crimp-on connectors, including butt splices and ring terminals. Terminal strips (fig. 8) are available in many shapes and sizes. They’re great for simplifying wiring on modular or sectional layouts and can minimize solder joints on other layouts. Suitcase or tap-in connectors (fig. 10) allow you to connect a feeder into a bus wire without having to strip either wire. Snap the connector in place on the bus wire, slide the feeder into its slot in the connector, and use a channel lock pliers to clamp the metal piece into place. The metal strip cuts through the insulation, making contact with the two wires. Many brands of suitcase connectors, also known as “insulation displacement Soldering Soldering makes solid connections, and if done properly the joint will be as strong as the wire itself. A pencil-type iron rated at 25 or 30 watts (see fig. 3) works well for smaller wires, but the larger pistol-style soldering guns are handy for heavy wire. I prefer a penciltype iron – it provides enough heat for most applications. Keep the soldering iron tip clean and tinned with a light coat of solder. Have a damp sponge handy and periodically wipe the hot tip on it to keep it clean. The best solder for model railroad wiring is rosin core 60/40 (60 percent tin/40 percent lead), although there are Fig. 6 COMPLETED JOINTS. Joints should be shiny with the solder melted within both wires. The T-shaped joint is a poor joint – the solder only flowed onto the feeder wire, a sign that the larger wire did not get hot enough. Fig. 7 HEAT-SHRINK TUBING. A finished joint is shown at top. Be sure to thread the tubing onto the wire before soldering the joint. Rub the tubing with the side of the iron, not the tip, to make it shrink. Fig. 5 SOLDERING. Heat both wires with the iron, then touch the solder to the wires (not the iron). The solder should flow into the joint. Fig. 8 CRIMPING. Add spade or other terminals to wire by threading them onto the stripped end and crimping them in place. Fig. 9 OTHER CRIMPED CONNECTIONS. Butt joints, as well as ring terminals, can be added using a crimping tool. connectors” or “IDCs” are available. I prefer 3M’s Scotchlok brand because the metal strip cuts through in two locations, providing better electrical contact. Keep it neat It’s tempting to make wire runs as short as possible, but this can create a rat’s nest under a layout. I like to route the main track power wires under the main line to keep the track feeders as short as possible. Label all of your wires, and colorcode everything – don’t rely on your memory to recall whether the blue wire is the switch machine positive, half of the lighting supply, or the north rail. When routing wires, use wire staples to hold the wires in place. See fig. 11. Using ordinary staples or wire nails crimped over wires can cut into and damage wire, leading to short circuits and other failures. Remember the keys to wiring: Keep it neat and do it right the first time. Using the right tools will make wiring less of a chore, and more importantly you’ll save time for more important things, such as running trains. 1 Jeff Wilson is a former associate editor of MODEL RAILROADER.

Control panels C ontrol panels are a great way to centralize all the switches and buttons needed to control everything on the layout in one central location. Making good-looking control panels may seem hard, but luckily a tool has become very common these days that makes it easy to create neat control panels. Enter the personal computer. PHOTOS BY BILL ZUBACK CONTROL PANEL Computer panel theory Recently I got serious about adding control panels to my Southern New England. I wanted the panels to be neat and easily understood by operators. I also wanted them to be fairly unobtrusive. I didn’t want the control panels to be the first thing catching visitors’ eyes when they see my layout. I’ve seen some intimidating control panels bolted to the sides of model railroads – and I used to earn my living in the Combat Information Center on an Aegis guided missile cruiser. Perhaps that’s where I learned the simpler and easier to understand a control panel is, the better off everyone will be. To use a buzzword a control panel is an interface between the user and the layout. Perhaps the simplest panel is nothing more than a track diagram with the various tracks labeled so operators will know where to set out or pick up cars – the panel isn’t used to control the trains or track. At the other extreme is a control panel with all the throttles, levers, and switches needed to control everything from one central point. My panels fall somewhere in the middle. With walkaround control I don’t need to mount throttles to the panel. I also don’t need to worry about block power or cab assignments since I use command control. My panels tell operators what town they’re in, identify the various tracks by name, number, or purpose, and localize turnout control in one place. But even if you’re not using command or walkaround control, there’s no Toggles To switch motors Drill holes to clear toggles Terminal strip Fascia Marty prewired the toggles before installing them on the panel. reason you can’t make your control panels the same way I created mine. Computer control panels The illustration shows how I made the panels. I started by using the simple line drawing software on my PC to create a track schematic. The panel shown is for Palmer, one of the more complicated areas on my layout. I began by drawing a box the size of the control panel and shading it in black. Then I followed the track plan to create a schematic drawing of the location, making sure to leave sufficient finger room for the toggle switches used to control the switch motors. I then identified each track by name or number, just like prototype railroads. This is an easy way to add some real world flavor to any model railroad and makes it easier on operators. With the drawing complete I printed it in black and white and created a dummy panel from a piece of cardstock. This is a good way to double- .060" styrene Computer printout .015" clear styrene ILLUSTRATION BY RICK JOHNSON check the spacing and location of the switches and lettering. I found I had to move some of the track labels since they would be obscured by the toggles. I printed the control panel on my laser jet printer and used spray adhesive to apply it to some .060" styrene. Then I drilled holes for the toggles through the styrene. I used the panel as a template to mark the hole locations on a piece of .015" clear styrene. Once I drilled the holes in the clear sheet I installed the toggles and secured the panel to the fascia with small screws. One tip – run the wires from the panel to a terminal strip under the layout near the panel location. Then run the wires from the terminal strip to the layout. This will help troubleshoot any problems and will make the wiring look much neater. 1 Digital Command Control By Cody Grivno Photos by Jim Forbes and Carl Swanson 6:00 PM 6:12 PM 1 MOUNTING THE POWER STATION THE POWER STATION 2 CONNECTING AND COMMAND STATION The power station (referred to as a “generator” by Atlas) provides the power to the command station and ultimately the trains. I mounted the power station on one of the 1 x 4s used to support the legs of the layout, which also happens to be directly below where the command station will be located. It works best to mount the power station and command station close to each other so you don’t have to run long lengths of wire, which might cause a voltage drop and lead to other operational difficulties. After I mounted the power station to the layout, I swapped the layout’s DC power pack for the command station, mounting it with Velcro fastener strips. This made it easy to remount and work on later. I wired the two units together using different colored wire to make them easy to trace. It’s also good practice to tin the ends of the wire (coat them with solder) to prevent any stray pieces from touching other connections and creating a short circuit. DCC systems are much more sensitive to short circuits than DC. 8:18 PM 8:33 PM 5 DRILLING A FEEDER WIRE HOLE 6 SOLDERING THE FEEDER WIRE Since the original track plan had only one wire running to the interchange track, I needed to add a second wire. That meant I had to drill a feeder wire hole. I used a pin vise and a no. 60 bit on the top of the layout. Don’t worry if the hole is too big. You can come back later and fill it in with ballast. In order to run the wire underneath the layout to the command station, I enlarged an already existing opening in the hollow-core door with a utility knife. With the wire run through the hole, I was ready to solder the feeder wire to the rail. Use caution when soldering the wire to the rail so you don’t melt the plastic ties, and be sure to clean any paint off the side of the rail so the solder has a surface to stick to. Once the new connection is cool, use needle files to shape any excess solder to the contour of the rails to prevent derailments. Touch up the soldered area with paint so it blends in with the rest of the rail. N ot long ago, MODEL RAILROADER’S editor Terry Thompson challenged me to convert a small N scale layout to Digital Command Control (DCC). The goal was to see if I could finish the project in an evening. On the surface this seemed like an easy task. However, all of my own layouts to this point had been direct current (DC) operated, so this was to be my first real experience with DCC. The layout I had to convert was the Carolina Central, an N scale project layout from 1996. Since the layout had been designed as a beginner’s project, the wiring was simple and offered only limited operating potential. With DCC, however, block controls would be unnecessary, and we could enjoy the accessory functions of DCC, such as controllable lighting and sound effects. After reading the instruction manuals provided with the Atlas Master DCC System, I was ready to begin. So come along and see if I can convert this layout to DCC in an evening. 1 Bill of materials 18 or 20 ga. model railroad wire Subminiature double-pole double-throw switch Razor saw Screwdriver Solder Soldering iron Pin vise no. 60 drill bit Utility knife Wire cutter More on our Web site To see the DCC-controlled Carolina Central in action, visit our Web site www.modelrailroader.com. in an evening 6:38 PM Converting an N scale layout to DCC 6:52 PM CAROLINA CENTRAL DCC WIRING DIAGRAM Terminal rail joiners Insulating rail joiners D C Q P K J VU Generator 3 CUTTING THE RAIL With the operational hardware in place, the third step is to begin preparing the layout for DCC operations. Start by creating an isolated section of track for programming each locomotive’s decoder address. It works best to use a siding or seldom-used track as a programming track. I used a razor saw to cut gaps in the rails on the layout’s interchange track. Be sure to cut the gaps carefully so you don’t damage nearby rails or scenery. After the gaps were cut, I smoothed out the rough spots with a needle file. Single-pole double-throw switch Single-pole single-throw switch Double-pole double-throw switch Command station 4 ADDING A DOUBLE-POLE DOUBLE-THROW SWITCH ILLUSTRATION BY RICK JOHNSON With a double-pole double-throw (DPDT) switch in hand, I was ready to begin the most time-consuming part of this whole project: replacing the single-pole singlethrow (SPST) switch with a DPDT switch. The DPDT switch allows you to use the interchange as the programming track. When the switch is set for programming mode, the isolated section of track can’t be operated. Once finished programming a locomotive’s decoder, setting the switch to operational mode restores power to the programming track. To run multiple locomotives, I had to give each locomotive its own two-digit address. When operating the layout, you can toggle back and forth between the two locomotives to control them independently. After roughly three hours of work, the Carolina Central has been converted to DCC. Now we can run multiple trains on the layout at the same time, adding to the operational fun of this small layout. 9:05 PM 7 RUNNING THE TRAINS The final step, and the one that lets you know if the wiring was done correctly, is to program the locomotive’s decoder address. The steps for programming the locomotive’s decoder are included in the instruction manual. PRODUCTS I N F O R M AT I O N S TAT I O N Getting started in Proto:87 modeling A small layout you can build Roque Bluffs, a Maine Planning a “no room for a layout” layout By Iain Rice Photos by the author T he various MODEL RAILROADER project layouts built over the years have assumed many shapes and sizes, and several have introduced new concepts and techniques. This project layout is one of the smallest yet, and the first to be conceived and executed outside the United States. Those of us living outside the U. S. have had to become adept at squeezing a lot of visual and operational interest into very small layouts. Many of our layouts are also portable and make use of lightweight construction materials. These are all concepts relevant to a growing number of U. S. modelers. Our Roque Bluffs (pronounced “rock bluffs”) project layout has a U. S. setting but explores many European layout ideas, including the use of Proto:87 (P:87) HO track and wheel standards that are closer to actual 1:87 scale prototype dimensions. P:87 is also similar to the British Protofour system. Commercial P:87 products, notably NorthWest Short Line’s superb wheels, are now widely available, and most aspects of fine-scale modeling can be PART 1 Seaport 1. Watched by a row of curious Sheepscot gulls atop the rendering plant, Maine Central U18B no. 403 makes a rare appearance at Roque Bluffs, our 11⁄2 x 12-foot shelf railroad built to Proto:87 fine-scale standards. designed around a cassette system, which allows me to use a common staging board for the various layouts with trains that rest on movable cassettes (see “Staging solutions” in the April MR). However, conventional staging would work just as well for Roque Bluffs – it would just need more space than I have available. The display slot in my office has a permanent backdrop and built-in lighting. It is situated 44" above the floor, a good viewing height. All my layouts use the same basic control system. When my layouts are not in use, I store them on racks in my basement utility area. My layout-building bench is also in this area. I have an additional bench in my workshop (an 8 x 12-foot garden shed). This arrangement ensures that I keep messy work out of the living areas of our small home. It also allows me to have two layouts “on the bench,” one set up in my office and two more stored on the racks. As a self-contained portable layout, Roque Bluffs and its cassette staging board can be set up in any 12-foot-long space. I designed Roque Bluffs to be the kernel of a larger model railroad as it can be easily extended at either end. The joys of stub terminals accomplished with familiar techniques. Our Roque Bluffs project shows you just what is entailed in building a layout to P:87 standards, but it can also be easily adapted if you wish to build it to normal HO practices. Site? What site? Roque Bluffs is a “no room for a layout” layout. It sits in a gap between the upper and lower bookshelf units in my home office. This tight space allows a total layout size of 11⁄2 x 12 feet, with height restricted to 17". Roque Bluffs is one of five layouts that I’ve built to fit this space, enabling me to overcome one of the main drawbacks of small layouts – lack of scope – by changing the entire layout. The other layouts are my P:87 1950s Dutch steam tramway, two different British railway terminals in P4, and a French-prototype HO meter-gauge layout. And no, they’re not all finished! All the layouts are sectional and portable. With the exception of the Dutch tramway, they also all require an add-on staging board. My staging is A stub terminal with a fiddle yard is a very popular subject for compact layouts in Europe. First, it needs a single set of staging tracks as there’s only one way out of the dead end. Feeding the end of a branch line direct from staging means that trains always depart the same way, avoiding any problems of orientation. Second, terminals often have more interesting track layouts and more complete facilities than through stations, with runarounds, extra spurs, engine terminals, and so on. Finally, they are more interesting to operate – no one gets to highball right on through! Terminals take many forms. In Europe, the country branchline terminal has long been popular with modelers, but many of these are quite large and difficult to compress. More recently, cramped city, industrial, and harbor terminals have become common small-layout subjects. Roque Bluffs is the terminal of a fictional branch inspired by the real Eastport Branch of the Maine Central (MEC), which ran south-eastward from 2.

Staging A BRIEF HISTORY OF PROTO:87 WHEEL AND TRACK STANDARDS P roto:87 (P:87) wheel and track standards for HO scale are very close to true prototype dimensions reduced to 1:87 scale. The standard was first set out as long ago as 1966, when the Anglo-Australian Model Railway Study Group (MRSG) produced workable truescale standards for a number of popular model railroad scales. Two MRSG standards have found widespread favor in Britain: 4mm/ft, 1:76 (known as Protofour or P4) and 7mm/ft. 1:43 O scale (Scaleseven or S7). In North America and parts of mainland Europe, the related 1⁄4" O scale standard, 1⁄4 AAR or, more recently, Proto:48, has also been taken up. These standards have been well-proven in three decades of use. Proto:87 has a much shorter history. The most notable pioneer was British modeler Brian Harrap, who built a complex HO triple-gauge Austrian-prototype layout in 1989 using the standard. Brian was followed by other groups and individuals in Europe who decided to experiment with the MRSG dimensions; in the Netherlands, the Anglo-Dutch Scalefour Society set out to build an ambitious Dutch P:87 layout, Portiershaven. In the process of evolving their layouts, the Dutch modelers commissioned British manufacturer Alan Gibson to produce commercial P:87 components such Proto:87 standards use wheel and track dimensions that are close to 1⁄87 of prototype dimensions. as locomotive and rolling stock wheelsets, and wheel and track gauges. The availability of these critical components led others to take an interest. In the U. S., P:87 modeling started with the launch of the P:87 Special Interest Group Web site, which attracted interest from around the globe. Ideas were exchanged, and various individuals set out to see how P:87 would work in a U. S. context. Canadian modeler Rene Gourley produced some of the first P:87 North American models, which included a Canadian National SW12 switcher and modern freight cars converted from commercial models, together with scratchbuilt 1890s-era equipment. Discussion within the SIG covered a wide range of topics, but it was the fusion of the European experience with well-established National Model Railroad Association procedures and proven modeling techniques that led to practical solutions and put the MRSG P:87 standard firmly on the path to becoming a worldwide norm. P:87 became a viable option for North American modelers with the arrival of commercial components and gauges. Roger Miener, a P:87 SIG member, persuaded NorthWest Short Line to produce P:87 wheelsets, while member Ed McCamey designed and had NMRA-pattern P:87 gauges laser-cut in stainless steel. Paul Dolkos covered P:87 in his November 1998 MODEL RAILROADER article, “Proto:Scale – Standards based on the prototype lead to greater realism.” Recently, Kadee has started to produce its close-to-scale no. 58 coupler, with other couplers arriving from Sergent, McHenry, and Accurail. – Iain Rice More on our Web site To read the November 1998 “Proto:Scale” article by Paul Dolkos, visit our Web site at www.modelrailroader.com 3.

A carefully thought-out track plan makes the most of limited space. A small layout you can build Roque Bluffs Lightweight bench No space for a layout? Start by looking in your office By Iain Rice Photos by the author L ast month I introduced you to Roque Bluffs on the Maine Central, a shelf-type HO project layout built to Proto:87 practices. (You could also easily build this railroad in traditional HO.) This month I’ll show how I found room for a model railroad in my “no space for a layout” house and how I built the lightweight and sturdy benchwork for Roque Bluffs. A model railroad slot Roque Bluffs is one of five interchangeable layouts I’ve built to fit an 18"-deep, 121⁄2-foot-wide display space – I call it the “slot” – in my office bookshelf system. Because I have a variety of layouts to choose from, I can change my model railroad whenever the mood strikes me. The shelf units in my office consist of a 44"-high free-standing lower unit and a wall-mounted upper unit. In between is a 17"-high by 121⁄2-foot-wide space that’s ideal for a shelf layout. To make a base for my interchangeable layouts, I installed a 15"-wide piece of laminated 1⁄2" particle board. Home improvement stores sell these boards as shelving. I made sure the board was level and square before I firmly screwed it in place on top of the bookshelves. The shelves house my collection of model railroad magazines, which I keep in large-size laundry detergent cartons. The boxes are efficient and cost-free but are not pleasant to look at! Thus, I conceal the soap cartons behind drapes that run on nylon curtain track supported by a strip of 1 x 2 lumber mounted under the front edge of my new shelf-top. As the layouts are mostly a tad wider than the 15" top, the curtains are effectively set back some way beneath the layout front fascia. A perspective drawing of my model railroad slot is shown in fig. 1. Lighting Roque Bluffs Another particle-board shelf runs above the layout display slot, which is also 15" deep and spans the full 121⁄2 feet of wall. This shelf is framed with 1 x 2 lumber and supported by heavy-duty shelf brackets, one on every other wall stud, as it carries quite a load – files, more magazines, and boxes of photographs. It also keep dust off the layout and supports the layout lighting system. Concealed 35-watt fluorescent lights illuminate the railroad. The 4-foot “slimline” lights have small-diameter tubes and are mounted sideways on the 1 x 2 framing that supports the top shelf. I nailed a 4" fascia strip to the front of the shelf to hide the fixtures. Mounting the lights at the front of the display ensures that the forward edge of the layout is adequately lit. Ideally, these lights should be another three or four inches out from the wall – but there isn’t space to permit this and still open my office door! I prefer fluorescent lights for model displays. First, fluorescent tubes are not “point” light sources, which dodges the multiple-shadow effect that often results from using a number of incandescent lamps. Second, fluorescent lights produce little heat – an important consideration when the lights are as close to the models as these are.

Fig. 2 BASE ASSEMBLY Medium-density fiberboard base third, the soft-focus, even illumination is much closer to the way daylight falls on a scene, provided you want a soft northern autumn light and not a searing noontime in Nevada! Mounting blocks for top board Plywood crossprofile board 1"-square glue block Lightweight benchwork and girders Roque Bluffs is made of three 4-foot sections. This design allows me to easily disassemble and transport the layout. For any truly portable model railroad, the benchwork sections must be made small enough, strong enough, and light enough to be easily handled. I made the benchwork sections of the Roque Bluffs layout from good-quality 1⁄4" plywood, 3 ⁄8" medium-density fiberboard (MDF), cardstock, and even paper. I used adhesives, staples, fine steel nails, drywall screws, nuts and bolts, and Velcro to hold it all together. Roque Bluffs is built on a surface of 3 ⁄8" MDF, which is smooth, stable, and rather hard. The MDF is supported by mini L girders made from 2"-wide strips Secure with 3⁄4" drywall screw Water surface Rear L girder 2" Hot glue bead Hole for wiring run if needed Slot to fit over T girder 3⁄4" 2" fillet also makes good gluing block Mounting blocks for Masonite fascia Small finishing nail Front T girder Plywood splice plate Add-on support between profiles as needed Fig. 3. Accurate benchwork. The benchwork of Roque Bluffs varies in height with the surface features it supports. To create an accurate template for the benchwork, Iain first drew a full-size plan of the Roque Bluffs on the same sheet of medium-density fiberboard that will eventually form the three levels that make up the top of the layout. Fig 4. Custom-fit framing. With a layout template drawn full-size on the medium-density fiberboard base, Iain knows exactly where he needs to place his L-girder benchwork in order to support the different levels that will be present on the finished layout. of 1⁄4" plywood. My local home improvement store cut 12 of these strips for me, each 4 feet in length. Slicing them from a standard 4 x 8-foot sheet of plywood was economical and quick. In a traditional railroad layout, Lgirder benchwork is used because it can support considerable weight across a long span. For that reason, L girders are usually made from substantial pieces of lumber that are glued and screwed together. However, the essential virtue of the L girder is that each leg of the L braces the weak (thin) dimension of the other leg. That remains true regardless of the girder’s size. Since the three sections that make up Roque Bluffs are only 4 feet long, the mini L- or T-section girders I made from 1" x 2" and 2" x 2" strips of 1⁄4" plywood provide ample strength and stiffness for the structure. I glued the girders together using a high-strength resin-based woodworking adhesive. To hold the wood while the glue cured, I hammered in fine steel nails and used staples from a staple gun. Most of the girders are 2" x 2" sections, but the front girder on the right-hand board, where the water of the harbor extends inward to the rear of the scene, is an inverted 1" x 2" T girder. I cut plywood cross-members and glued them inside the L girders to serve as frame cross-braces and as supports for the MDF top, as shown in fig. 2. The 2"-wide girders at the base of the structure make a good reference surface and sit evenly on the shelf that supports the finished layout. For this reason, I set the support girders a bit less than 15" apart to fit on the width of the base shelf. All track is arranged within this 15" width. The area of the model cantilevered outward from the front girder is scenic foreground (mostly water areas on the Roque Bluffs). Correctly shaping the cross-profiles of the framing is essential. Each part of the framework supports a particular area of the model, so the track or other surface feature determines the outline of each part of the framing. Roque Bluffs has three main levels – the water surface, the land surface, and the raised roadbed of the cannery spur – and these profiles have simple outlines. I just had to be careful that my framing did not interfere with any of the subtrack-level features. Roadbed and water surfaces Fig 5. An even playing field. The L and T girders are made of high-quality 1⁄4" plywood glued with woodworking adhesive. By building the benchwork on a level shelf, Iain knew his lightweight but strong framing would also be level and square. Before doing any cutting, I sketched a full-size plan in pencil on my 2 x 4foot MDF sheets. I then temporarily laid all the track using flextrack, overlapped at the turnout locations, to check clearances and radii. I find this works well, as it’s easy to adjust flextrack by eye to get nice smooth curves and transitions and to make sure there are no awkward kinks or tight spots. I also find it much easier to mark track positions on the boards when I’m using actual track. I held the flextrack in place with thumbtacks and marked just outside the tie ends to establish the foundation area of the track. The twin lines make it easy to position the foam roadbed strip. At the locations where the tracks extended over the water on the pier and the trestle, I marked the track position on the water surface. I’ll build all the track-supporting structures when I lay the track. When I was satisfied with the position of all the elements on the layout, I inked the lines with felt-tip markers (fig. 3). I used a color code: track edges in green, structure positions in black, and cut-lines in red. To make everything absolutely clear, I also outlined and cross-hatched the watery areas in blue. I then used a saber saw to cut the gently curving front of the layout and carefully smoothed the edge with an orbital sander. I used the marked MDF base pieces as templates for assembling the framing (fig. 4), knowing that the support structure would match the surfaces it supported. Fig. 6. Site-specific considerations. Iain has set his long main support girders so they rest solidly on the 15"-wide shelf the layout will occupy. He gained a few extra inches of width by cantilevering part of the layout outward from this shelf. While all of the tracks will be supported by the main benchwork, the extra few inches will become a scenic foreground. Assembling the benchwork Benchwork accuracy depends on careful assembly. Building on a flat surface – in my case, a level shelf – ensured that the finished base would be both level and square, thanks to the wide bottom elements of the L girders resting flat on the shelf, as shown in fig. 5. I assembled the benchwork framing with woodworking-grade adhesive applied with a hot-glue gun. Fine finishing nails held the girder pieces in position until the adhesive cured. I set the end profiles first. These were made as a matched pair cut from two pieces of 1⁄4" plywood clamped together with 1⁄4" bolts. I left the bolts in place until all the framing had been assembled. With the whole layout accurately aligned from the start, I knew that Roque Bluffs’ three sections would always go back together as intended. I built the framing around the endprofiles and girders. First I lined up the girders of the adjacent sections on the end profiles and glued them in place using dots of hot glue on the base flanges of the girders. Then I reinforced each corner with 1" square blocks glued with the resin woodworking glue. I let Fig. 7. Finishing the benchwork. With his frame of L- and T-section girders completed, Iain no longer needs to use the plan drawn on the fiberboard as reference and can cut the board to separate the three main levels of the layout and attach them to the top of the benchwork. the adhesive cure before adding the rest of the framing. I had a problem with excess adhesive squeezing out and gluing the sections together. I should have trapped some sheet plastic between the adjoining endprofiles before I bolted them together. I fitted my remaining cross-profiles in place on the girders and glued and nailed them in place. I made the cantilever pieces in front of the T girders individually to fit their location (fig. 6) and similarly glued them in place. To reinforce each joint between a cross-piece and a girder, I placed a glue block and added additional blocks along the top edges of the cross-pieces where they would join the baseboard surfaces. Once the adhesive cures, this type of light benchwork is robust and surprisingly rigid. When I finished gluing the frame, I no longer needed to use the MDF piece as a template. I cut out the water, land surface, and raised track areas with a saber saw (fig. 7). I glued these pieces on the cross-members with resin adhesive secured with 3⁄4" drywall screws. I added a Masonite fascia later, after installing the turnout motors. Speedy construction The light, solid, and strong benchwork for Roque Bluffs was not expensive or time-consuming, and it enabled me to move speedily to the actual construction of the layout. Next month I’ll show how I selected and detailed the right mix of freight cars to serve the layout’s industries, and I’ll share some tips for giving rolling stock a Proto:87 makeover. 1 A small layout you can build Roque Bluffs, rolling Developing an equipment list and finding the right level of detail By Iain Rice L ast month I described how I prepared a location in my home office for my Roque Bluffs shelf-type HO project layout and how I built the railroad’s lightweight and sturdy benchwork. This month I’ll show how I developed a realistic mix of rolling stock for my fictional Maine Central branch line. Photos by the author Roque-ready rolling stock “Hold on!” you say. “How come we’re talking about rolling stock before an inch of track has been laid?” The answer is logistics. Roque Bluffs will be built with the more true-to-scale Proto:87 (P:87) HO track and wheel dimensions. Track needs to be tested as it’s laid, and to test P:87 track you need P:87 equipment. Motive power for Roque Bluffs is a straightforward proposition, even for a slightly obscure railroad like the Maine Central. For many years, the Maine Central kept a General Electric 44-ton diesel locomotive at Calais to work its Eastport branch. Alco S-1 and ElectroMotive SWs were also used. All of these PART 3 stock An Alco for Roque Bluffs When he encountered Life-Like’s sweet-running and well-detailed Proto 2000 Alco S-1, Iain Rice knew he had found the right motive power for his Roque Bluffs HO project railroad. locomotives have been produced in Maine Central colors in HO. Rolling stock is even less of a problem than motive power, but first I had to think about the level of detail that would be standard on the Roque Bluffs. The tread width of the wheels is the major difference between a P:87 car and a standard HO scale car with wheels made to RP25 (the National Model Railroad Association’s recommended practice for standard HO). But there’s a bit more to P:87 modeling than swapping wheelsets. I’ve found that work lay in bringing equipment from other – mostly older – sources up to the same level of detail and finish. While I do try to make my models authentic, I’m not a freight-car expert, and I’ve relied greatly on those who are for advice. I felt that if I avoided obvious visual anomalies like molded-on grabs, the cars would at least look okay to me and to everyone else except the experts. ultra-fine details may be prone to damage on an operating layout, but I still wanted an amount of detail that complemented the finer wheels. My ideal specifications list included P:87 wheels in scale-width trucks, where possible; scale-sized couplers, with no trip pins; scale wire grabs; delicate ladders, stirrups, and running boards; and realistic paint jobs. Recent equipment from Proto 2000, InterMountain, Bachmann, Kadee, Red Caboose, and Athearn met my specifications right out of the box. The real Choosing a locomotive was my first step in equipping Roque Bluffs. Initially I envisioned an SW7 in Maine Central’s later “solid green” switcher scheme – a choice helped by the fact that I already had an undecorated Athearn SW that I knew was a cinch to convert to P:87. The work was coming on quite well when, in search of a Detail Associates etched SW front grill, I paid a visit to Henry’s Hobby House in West Boylston, Mass. Fate was smiling that day, for the store had just received new models from Life-Like. One look at Life-Like’s Proto 2000 Alco S-1 in razor sharp Maine Central black-with-red-stripe factory paint and I forgot all about SW7s! NorthWest Short Line’s no. 27691-4 P:87 wheelsets for Life-Like engines are easy to install. After I installed a set of Kadee no. 58 scale-size couplers in place of the original couplers, the 953 was ready for service. I added the appropriate details supplied with the model and installed a pair of Cal-Scale no. 280 brass marker lights on the nose in approved Maine Central style. I reworked the paint slightly to vary the shades of black – allblack engines are rarely uniform in color, and using different shades on trucks, frame, cab roof, and walkways really brought the model to life. The step-well ends on the pilot were picked out in Harvest Gold. I also chemically blackened the bright sides of the NWSL wheels and lightly brushed them a rusty-greasy brown. All the new paint was brush-applied Polly S or Humbrol acrylic, and the engine received a moderate weathering with powder to blend the finish and dull the lettering and stripes a tad. This model is superb and runs like a Rolex. It also tracks very well in its P:87 form and negotiates all the nooks and crannies of Roque Bluffs without problem. Finding the right caboose Life-Like also supplied the caboose for Roque Bluffs. The Life-Like model has excellent detail and quality of finish and is a dead-on match for the prototype – except for its color. It seems that no two manufacturers agree on the shade of Maine Central’s Harvest Gold. (Judging by the color variations in photos of the real thing, the railroad itself wasn’t too sure!) The dull orange of the Life-Like caboose is the most extreme variation I’ve encountered. I may repaint this car, but for the moment I’ve contented myself with a set of NWSL wheels, no. 58 couplers, and a touch of paint and weathering to complete what was literally a half-hour project. It’s a dinky little crummy and it looks absolutely right for Roque Bluffs. Choosing the right freight cars Before buying freight cars, my first task was listing the traffic generated by the on-line industries and the car types needed to handle this lading. With a tiny layout like Roque Bluffs, there’s a finite number of cars that can be handled, so I restricted my choice to around 20 pieces. My traffic and car-type list is set out in the table on page 115. My predominant need was for boxcars – no surprise, as these are usually the most common general-service cars. Looking at pictures of Maine Central trains, though, I was struck by the relatively high number of home-road boxcars found in its trains, so I decided the mix of road names would strongly favor the home team. Covered hoppers, on the other hand, seemed to come from all over the place and fish meal (a fertilizer and a feed for fish-farms) is a general lading not requiring dedicated hoppers, so I reckoned I had a free hand. I went for a mix of older two-bay and newer cylindrical and multi-bay hoppers. Tank cars come in two basic variants – single-compartment (and single-dome) cars handling one product only, and two- and three-compartment Stock HO to Proto:87 in 5 easy steps cars that can carry a mix of products. I purchased both a single-dome car and a three-dome car to serve the customers at Roque Bluffs. P:87 car conversions All the equipment at Roque Bluffs rolls on NWSL P:87 code 64 wheelsets, and about half the cars ride on scalewidth trucks from Eastern Car Works. The company also sells P:87 bolsters that fit its standard truck kits. As they currently offer 19 truck types, you should be able to find something suitable! Most of my stock rides on the common Barber 100-ton S-2 rollerbearing trucks. Equipping newer cars with Eastern Car Works’ scale-width trucks and the NWSL no. 37677-4 P:87 wheelsets on .917" axles is generally simple, except on some Athearn cars where the ECW bolster gives a ride height that is too tall. The Athearn truck mount doesn’t permit lowering, and the alternative – thinning the ECW bolsters – made them too flexible. I had to reinforce them with strips of .060" square styrene strip. The only other snare with the ECW trucks is ensuring that you cement them truly square and flat. I made a couple where the axles ended up a tad skewed, leading to instant derailments. I now assemble the truck sides and P:87 bolsters on a piece of plate glass using Plastic Weld liquid cement, checking the truck alignment with a small square while the joint is still soft. I make sure to let the joints cure hard before I gently force the sides slightly outward to ease the wheelsets in place. The resulting ECW trucks run freely without any slop in the fit of the axle pinpoints in the truck frames. That’s vital, because any play in the wheelsets 1 Remove the truck sideframes by unsnapping the lugs at the truck ends and withdrawing the central locating pins from the contact strip and truck side. Take care not to damage the leads from the contact strips and the brake chains on the rear truck. is a strict no-no in P:87. Trying to get narrow-tread wheels onto the rails when they can move around in the truck frames is almost impossible. This proved to be a problem with most original-equipment trucks and some otherwise excellent replacements such as the equalized InterMountain trucks. Even using the version of the NWSL P:87 wheelset with the longer axle left way too much movement with most types of “wide” trucks, although some recent castings by Atlas and LifeLike (the Proto 2000 “Bettendorf” is very good) proved to be fine. I found that it was possible to adapt standard-width trucks to take the longaxle NWSL P:87 wheelsets by drilling the bearing seats in the truck frames a little deeper with a 2mm drill and inserting brass bearings to take out the end-float on the axles. The ones I used are either Peco type R30 or the turned “top hat” type widely used by British modelers. I purchase mine from Mainly Trains, a mail-order specialist, at Unit C, South Road Workshops, Watchet, Somerset TA23 0HF, UK; the Web site address is www.mainlytrains.co.uk. A multitude of couplers When I started out on this project, the only closer-to-scale alternative to the normal Kadee no. 5 (or equivalent) knuckle coupler was the no. 711 “Old Time” coupler – essentially, the HOn3 coupler with longer trip pins. This coupler is, if anything, a tad too small for a modern knuckle, but it looks good. I used this coupler, without the trip pins, for the first few cars I built for Roque Bluffs. Getting a no. 711 to fit generally requires some shimming to locate the tiny coupler box at the right height for modern cars. 2 Slide a fine, straight-blade jeweler’s screwdriver in the middle of one side of the keeper molding to gently spring the lugs free of the truck gearbox and remove the keeper plate from the gearbox and set aside. Above: Iain decided that Life-Like’s Northeastern pattern caboose is just right for a branchline railroad. This model has excellent fine details right out of the box. All the caboose needed was P:87 wheels, Kadee no. 58 scale couplers, and a touch of weathering and it was ready for service. Left: Iain needs only about 20 cars to operate Roque Bluffs. Just as real railroads did in the era he models, Iain updated some of the older rolling stock by removing the running boards and lowering the ladders. 3 4 5 Remove the wheelsets from the truck. Pull out the Life-Like wheels with their stub axles. Push replacement NorthWest Short Line P:87 wheels with stub axles in place and use a caliper to set the back-to-back wheel spacing at 15.55mm. Note the difference in tread width between standard HO in front and Proto:87 at rear. When all the wheelsets have been replaced in the truck, snap the keeper plate back in place on the gearbox. Place 1.5mm-diameter by .020"-thick spacer washers over the axle ends outside of the wheels to take up the difference in width between RP25 and P:87 wheels. Place the contact strips over the axle ends outside the washers, and replace the sideframes. When I was a year into the project, Sergent, Kadee, and Accurail all announced couplers, and I obtained some samples from Sergent and Kadee. The cast-pewter Sergent looks great – and is nearly exactly to scale – but it has to be assembled, which is a tad tricky. The Kadee no. 58 arrives ready to drop into a standard no. 5 coupler box, making installation a cinch. Kadee also makes a no. 78 – an assembled no. 58 in a narrower box. I found that the Kadee nos. 5, 58, and 711 couplers all couple quite readily with Sergent couplers. Era-specific car detailing My chosen late-1970s/early 1980s period is at the time of changeover from traditional freight cars with running boards and full-height ladders to the modern standard of short ladders, lowmounted brake wheels, and no roof access except on cars – like covered hoppers – where it is necessary for loading. To accurately represent this period, I needed one or two unconverted boxcars with the traditional arrangement, a few slightly older cars that had been modernized by removing running boards and lowering brake wheels and ladders, and a handful of modern cars that arrived from the builder with a low-ladder arrangement. The first and the last were easy enough to come up with, but modernizing older cars proved quite tricky, especially starting with models with cast-on ladders. By the time you’ve carved away the ladders, running boards, and brake wheel platform and filled any resulting holes, you’ve made quite a mess of the factory paint job! Fortunately, the real railroads had the same problem, and it was quite common to see modernized boxcars with the end panels and ends repainted in not-quite matching colors or even patches of oxide red primer. So I touched-in the paint on my conversions without worrying too much about getting an exact color match and blended the colors with weathering. Otherwise, my freight-car detailing – such as it is – follows conventional lines. I use Detail Associates pre-formed wire grabs to replace the cast-on variety, and I generally make my own replacement stirrups using ordinary steel office staples re-bent. I find the flat-section staple wire is just about right to represent the steel strap section With NorthWest Short Line P:87 replacement wheelsets, Kadee no. 58 couplers, and a touch of weathering, this Atlas PS-2 covered hopper is ready for fish meal service. from which the real thing is made, and using four staples sliced off a standard refill strip makes it easy to produce a set of matching stirrups in one try. I attach wire details by either drilling holes and gluing them in place using CA (cyanoacrylate adhesive) or by carefully melting the stirrup into the plastic with a small soldering iron. The new ladders, brakewheels, and other plastic details are mostly from Detail Associates, Details West, and Des Plaines Hobbies. Air hoses are of fine wire, and uncoupling levers are bent to shape from .012" brass wire and held with loops of 40-gauge copper wire (a single strand of layout hookup wire) cemented into drilled holes with CA. The essential art of weathering I regard weathering as essential. Weathering aids realism, helps to integrate equipment into the overall layout context, and tones down the over-bright TRAFFIC AND CAR TYPES Industry Traffic and direction Car type Fish meal plant: Bulk fish meal, out Bagged fish meal, out Fish oil (in drums), out Fuel oil, in Covered hopper Boxcar Boxcar Tank car Cannery: Canned goods, out Empty cans, in Bulk ingredients, in Fuel oil, in Boxcar Boxcar Boxcar Tank car Oil Depot Diesel fuel, in Kerosene, in Gasoline, in Bunker-grade fuel oil, in Tank Tank Tank Tank Boatyard Steel plate, in Lumber, in Machinery, in Gondola Flatcar Boxcar Pier General merchandise, in Chandlery supplies, in Fresh fish/shellfish, out Boxcar Boxcar Reefer* Town: General merchandise, in Boxcar* car car car car Iain used a variety of scale couplers for his Roque Bluffs rolling stock.

Looking at a model is equivalent to looking at the prototype from some way off, so colors need to take account of the intervening distance – what artists call atmospheric dilution. The atmosphere is not totally transparent, so distant colors seem less vivid than those seen up-close. In art, colors are modified when being mixed to account for atmospheric dilution. This isn’t possible with prepainted models, so I start by giving the model an overall thin coat of a dilute blue-brown-gray mix of acrylic paints dusted on with the airbrush or washed on with an artist’s sable brush. I then add weathering tones as needed by painting or drybrushing with acrylics. I am careful to avoid any strong or pure colors, especially blacks. I never use pure black or white in model work – a dark brown or dark gray shade for black and a pale gray or cream for white always looks better. Finally, I use weathering powders to add traces of dirt and rust. The ones I use are British, made by Carrs, and you can order them from International Hobbies in California. Alternatively, ground-up pastel chalks work as well. Once I’m happy with the look of the car, I seal the finish with a dusting of MicroMatte acrylic varnish. I’m especially careful to weather the front and backs of wheelsets, the axles, the truck frames, and the couplers. A light dusting of weathering color with the airbrush doesn’t affect the function of the knuckles and makes these important items look as though they are part of the car. To help paint stick to wire or metal details like grabs or cut levers, I treat them with chemical blackening solution such as Blacken-It. This gives a good base for paint, and if the paint does wear or flake off, you don’t see bright metal. Iain likes the Kadee no. 58 scale couplers equipping this gondola. All Roque Bluffs rolling stock is manually uncoupled, and Iain reports that the various sizes of Kadee couplers he sampled as well as cast pewter couplers from Sergent couple just fine with each other. Keeping busy with a small fleet Equipment for a small layout like this offers a lot of scope for modeler input even if you start, as I have, with stock ready-to-run or kit models. I tend to gradually upgrade stock over time so as to keep a reasonable selection available to work the layout, and there’s still plenty of scope to improve the cars rolling on Roque Bluffs. Next month I’ll show how I built P:87 trackwork for Roque Bluffs. 1 The difference between scale-width P:87 wheels and trucks and standard HO wheels and trucks really jumps out at you when the two are set beside each other. A small layout you can build Roque Bluffs, realistic Great-looking handlaid track starts with simple tools and techniques By Iain Rice Photos by the author L ast month I showed how I selected and detailed the mix of freight cars to serve the industries at Roque Bluffs, our Maine Central project railroad. I also shared some tips for giving rolling stock a Proto:87 (HO fine scale) makeover using wheels that are closer to scale prototype dimensions. Although I used P:87 for this layout, you could build it using National Model Railroad Association standards. This month we’ll start laying track, but first a word of advice. Rough spots in the track that cause a barely detectable bump in standard HO will put those narrow P:87 wheels on the ground. Careful work at this stage will reward you with track that looks great and trains that operate smoothly. Precision track Proto:87 track differs from conventional HO scale track in one important aspect – the turnout flangeway clearances are narrower in P:87. Otherwise, all the techniques used to build HO scale track work just fine for P:87. There are two ways to make realistic track. You can either study full-size railroad engineering until you understand PART 4 track how it all works or you can look at prototype pictures of the railroad you’re modeling and copy what you see – which is what I did. I went through all the 1970s-era Maine Central photos I could find and took notes. For instance, I noticed the MEC didn’t worry too much about getting their tie-ends neatly aligned! Good track starts with good tools, and the most essential tool of all is the human eye. Your eye will detect kinks, doglegs, things that aren’t parallel, curves that lack nice transitions and – most essential – whether the track looks right. This is one case where the old maxim, “If it looks right, it will work right” applies. Model track that flows smoothly through curves and turnouts, transitions gradually between tangent and curve, and rises gently onto grades is likely to run well. Track materials Good-quality flextrack nicely represents well-maintained track, but that’s not the kind of railroad I’d expect in a backwater like Roque Bluffs. Handlaying my track also guaranteed that its appearance would match my handlaid Handlaid track and a few simple techniques allowed Iain Rice to accurately model the down-in-the-weeds look of a Maine Central branch line. turnouts. The materials I used are standard fare – Micro Engineering’s wood ties and Micro-spikes, with Peco and Micro Engineering rail in codes 55, 65, and 75. For unseen track or track destined to be embedded in pavement, I used printed-circuit board for ties and soldered the rail in place. In the November 2002 Model Railroader, I described how I marked my track locations using temporarily laid Using a marking pen, Iain outlined the location of the track on the layout’s surface, then he glued Woodland Scenics foam roadbed in place. The long ties at left are headblocks – the pair of ties that support the switch stands. Rails are held in place by paired spikes in every fourth tie. At rail joints where a little extra support is needed, Iain solders the base of the rail to a steel pin that he pressed into the layout’s medium-density fiberboard surface. flextrack and drawing parallel lines along the tie ends on the fiberboard base of the layout. I also indicated the locations of the turnout switch rods with the letters “HB” for headblocks – the two extra-long ties that will support the switch stand. I used this initial marking to place the Woodland Scenics foam roadbed strip, which is 17⁄8" wide. Since my tieend position lines are 11⁄8" apart, I simply drew an additional line 3⁄8" outside the tie-end marking. One line is enough – the side nearest the front of the layout being the most useful. I glued the foam roadbed to the layout’s surface with Walthers’ Goo, laying three beads along each strip – up the center and along each edge. The Goo gave me a minute or two to line up things to my satisfaction before it set. Weights kept the roadbed in place while the adhesive cured. At turnout locations, I either laid one length of roadbed strip right through the turnout and spliced the second piece to it for the diverging track, or I built up the track foundation using several smaller pieces of foam. It doesn’t matter if the joints aren’t snug – they will all be buried in the ballast. Laying wood ties I position wood ties according to the sort of track I’m modeling. In the case of Roque Bluffs the track needed to look bad! The Maine Central kept its main lines in good repair, but out in the boondocks the railroad’s spurs, sidings, and industry tracks were not nearly as shipshape. The tie ends didn’t line up, the rail was lighter and spiked directly to ties that were often twisted, split, or chipped. Some ties were considerably off-center because the section crew had shifted them to one side to find enough sound timber to hold a spike. The ballast appeared to be about 30 percent stone, 50 percent cinder, and the rest dirt. In most places, weeds crept right up to the tie-ends. Accurately modeling less-than-perfect track is an interesting challenge. I started by positioning the individual ties by eye, using a rail that I pinned temporarily in place as a guide. At this stage in the process, the rail location doesn’t have to be exact and neither does the tie positioning. I spaced and aligned the ties to suit their locations, closer together on the main running tracks and a bit farther apart on the spurs and run-around loop. I also sorted the Micro Engineering ties as I laid them, copying full-size practice by using the better-looking ties for running lines and using the not-sogood examples for spurs. I welcomed the occasional chipped or twisted ties and used them to make my weed-grown sidings look even more decrepit! I glued the ties to the foam roadbed with Goo, one tie at a time. A slow process to be sure, but it was the best way of achieving the slightly wayward tie placement I was after. I cut turnout ties roughly to length. I didn’t attempt to produce neatly graduated ties – prototype pictures showed the tie-ends staggered all over the place. I have a typical modeler’s urge to tidy everything up, and all of this went a bit against the grain. But the real world isn’t that tidy, and the real world is what we’re supposed to be modeling! I left most of the turnout ties loose at this stage to allow me to adjust their positions. The exceptions were the headblocks and the ties at the extreme ends of the turnout. Paved Track Quite a lot of the track at Roque Bluffs is embedded in concrete and other paving materials, as is common at dockside. You do need to ensure that the railheads are a few thousandths of an inch above the pavement to ensure good electrical contact and easy track cleaning. To model paved track, I soldered the rail to printed-circuit-board (PCB) ties. Ties spaced about an inch apart are enough for a strong result. Don’t forget that PCB ties require you to cut an electrical insulation gap in the copper foil On straight track use two gauges facing in opposite directions. Spike rails between gauges Outer rail Inner rail For curved track use two gauges set with two points on the outer rail (lay this rail first on curves) Gauge widened by this amount il er ra Out r rail Inne Principle of gauge-widening with 3-point gauges – exaggerated view Using three-point track gauges As is common with dockside railroads, the track will be set in pavement in several places on the Roque Bluffs layout. Since the ties will not be visible in these locations, Iain soldered the rails to printed-circuit-board ties. Illustration by Robert Wegner surface between the rails. I find it best to cut this gap with a triangular needle file before laying the ties, checking the isolation with a meter. It’s a lot easier to do this than chase short circuits once the track is laid. I will describe my paving techniques in detail in an upcoming installment of this series. Resilient roadbed and tiny spikes I’ve found that foam roadbed makes for smoother running, which improves wheel-to-rail contact and reduces derailments with fine-scale wheels. The tiny ME Micro-spikes hold only in the actual ties, and so handlaying track on a soft roadbed requires a slightly different technique than spiking on a firm roadbed like Homasote or cork. I first set one rail on the ties and held the alignment with straight pins pushed into the layout base on either side of the rail. I used a plastic ruler to align the rail for straight track. For curved track, I take advantage of a useful natural characteristic of the rail – it forms a smooth curved alignment of its own accord if you hold the ends in place and let the rail in between do its own thing. I drilled no. 78 pilot holes on either side of the rail base where I needed paired spikes – about every fourth tie was sufficient – then I pushed the spikes in with fine-tip pliers. Some of the ties were of harder wood than others. To overcome this, I placed the tip of a small screwdriver under the tie end as a support while driving the spike. To give the finished track more strength, I reinforced the rail location with cyanoacrylate adhesive, used sparingly, to lock the spikes in place. At points where rail location is critical or where lateral loads are high – as at an unsupported rail end or adjacent to the turnout switch rods – I soldered the rail to a pin driven into the layout’s medium-density fiberboard base and snipped the pin at rail-base level. There’s no point in having a nice springy foam roadbed if you lock everything solid by ballasting with stone chips and hard-setting glue. I use Woodland Scenics ballast – made, they tell me, from ground-up nutshells – held with a flexible white glue. The adhesive I use is low-strength stuff intended for use by children, but acrylic matte medium would work just as well. You need only enough adhesion to stop the ballast from coming loose. You don’t want to mix a sort of glueand-ballast concrete! I found it easy to end up with track that looked too good for the sort of rough-and-ready branch line I was after, so I used short rail lengths to get the slightly kinked look of the prototype. In an odd reversal of my usual priorities, I even deliberately arranged joints to meet on a curve rather than going all-out to avoid them! Automatic gauge widening Once the first rail was spiked down, I gauged the parallel rail from it using a Micro Engineering three-point track gauge. On straight track I use a pair of gauges, one facing each way, to ensure accuracy. But on curved track the two- point side, the base of the triangle, should always be on the outside of the curve, as the illustration shows. This gives automatic gauge widening – the tighter the curve, the greater the offset of the track gauge. To ease the friction between wheel flanges and the railhead, the gauge of full-size track is eased outward a fraction on curves. The tighter the curve, the more the gauge is eased, to a maximum of around 1⁄2". This may not sound like a lot, but it has a dramatic effect. With the P:87 wheelsets having the same relationship to the track gauge as the real thing, gauge widening of a few thousandth of an inch has a similarly beneficial effect. Turnouts made easy Starting with ties, spikes, and a pile of parts and ending up with realistic track is a very satisfying process, and it’s not too different from the way real railroads do it – only without the backbreaking toil! Next month I’ll finish laying track and show how I custom-made turnouts and crossings (“diamonds”) for Roque Bluffs.

This time I’ll show you how to build your own turnouts. This layout is “Proto:87” because of its track and wheel standards, but if you prefer you could use exactly the same methods to build track to National Model Railroad Association standards. Most model railroaders become accustomed to planning layouts around standard turnouts, or at least turnouts that are available in the larger product lines such as Shinohara or Peco. But if you make your own turnouts, the range is pretty well infinite, as once you know the basic rules you can build a turnout for any situation following any prototype. We’ve become a tad fixated with the common frog numbers – nos. 4, 6, or 8 – but real turnouts come in all sorts of odd angles. You don’t really have to care what the frog angle is, so long as it fits the situation on a layout. The rules of turnout construction are actually quite few and basic. The actual Toe end of turnout Fig. 1 Turnout terminology Fig. 2 Check gauge Flanges miss point of frog by .003" to .005" –a miss is as good as a mile! Back of wheel just clear of frog wing Headblocks Switch stand Points Frog Back of wheel in contact with guard rail Guard rail Check gauge Switch rod Stock rail Flangeway “Set” Adjust the guard rail position to set the check gauge, using a wheelset as a gauge (this works for any standard, not just P:87) “Set” is slight angle of stock rail to guide flanges onto point Closely spaced ties supporting heels of points Closure rails offset in the curved stock rail just where the nose of the point touches. This helps guide the wheels smoothly onto the switch. [The “turnout” is the whole assembly including the frog and the closure rails. The “switch” is the moving part of the turnout, the points that guide wheels onto one route or the other. – Ed.] All of these features are shown in fig. 1, which also names the parts of a turnout following full-size practice. Critical tie positions Stock rails Closely spaced ties supporting closure-wing rail joint Wing rails Ties supporting frog In the fifth installment of his Proto:87 layout construction series, Iain Rice explains how to scratchbuild turnouts in place, to fit any layout situation. Here’s the turnout leading to the Dolkos Oil track, with the train in the background on the “main line.” frog itself, where the rails cross, is normally straight. The switch points are “housed” into the stock rail, usually by machining the base of that rail to allow the point to fit snugly against it. There is also usually a “set,” a slight tweak or Wing rail “knuckles” Frog Guard rail Guard rail Wings of frog Heel end of turnout Illustrations by Rick Johnson Positioning the ties is a big part of turnout building. In standard turnouts railroads follow standard tie patterns, but certain tie locations are critical even in turnouts built to fit. Starting at the toe of the switch, there is always a pair of long ties on either side of the switch rod (the real name for what model railroaders usually call the “throwbar”). These are the “headblocks” that support the switchstand or turnout motor. The next critical ties are the switch heel ties – two ties close together to support the joint between the points and the closure rails. A similar pair of closespaced ties supports the joint of the closure rails and the knuckle rails. Then there is always a tie beneath the actual knuckles, another beneath the point of the frog, and a third beneath the frog wing rails. And, lastly, there are usually close-spaced ties to support the ends of the rails at the extreme ends of the turnout. I usually glue only the critical ties in place to start, and fit and glue the rest of the ties in place as I go. Proto:87 considerations In Proto:87 construction, the flangeways through the frogs are to scale, a maximum .024" wide. To get the rails this close, you need to file the inside Fig. 3 First stock rail. Iain positions the first stock rail on the ties and temporarily pins it in place. The “housing” where the point will fit will extend back from the headblocks. base off the wing rails at the frog. The actual flangeway width is easily set with an ordinary feeler gauge as used to gap the spark-plugs on an automobile engine. Flangeways that are too narrow will cause problems, but if they’re a bit wide I find they’re usually okay. The positioning of the guard rails, however, is critical in P:87, as they have to function exactly as in the prototype. Again, you don’t need to bother with measurements, although a gauge would come in handy. The important thing is that when the back of one wheel in a Fig. 5 Point of frog Base of rail (shaded) Railhead Gap Frog-point rails can be filed to more than half the desired frog angle; resulting gap will be filled with solder (color shading) Fig. 4 Second stock rail. Using track gauges and a metal weight, Iain positions the second stock rail opposite the first and pins it in place as well. wheelset touches the guard rail, as shown in fig. 2, the flange of the other wheel is still on the same side of the point of the frog. The clearance needed is small, only a few thousands of an inch, but it’s a very important few thousandths. Allow that flange to ride over a little too far and it’ll pick the frog, ride up over, and pow! – you’re in the dirt. Building turnouts in place Except for a Rail Works no. 6 used for the cannery spur, all the turnouts in Roque Bluffs were built on site following these principles and work fine. I determined the locations of the headblocks when first laying out the track, but I located all the other parts of each turnout as I built it by rule of thumb. With the headblock position fixed, the stock rails can be set in place and held by pins pushed into the sub-base on either side of the base of the rail, as shown in figs. 3 and 4. Then you can Fig. 6 Positioning frog rails. Iain positions the first frog rail from his “datum” stock rail, the far one in this case, which is already spiked down. The second frog rail is added to form the required angle from the first. mark the stock rails where the tips of the points will fit, over the headblock farthest from the frog. Form the housing to allow the point to fit tightly against the stock rail by filing away the base of the rail on a long taper back from this location. Start the actual rail laying by spiking down the stock rails from the headblocks back to where they join the last rails of the plain track, using four spikes in every tie to hold everything firm. Then select one of the stock rails as the “datum” – usually the straight one if it’s a standard turnout, or the “main line” or “normal” route through a wye or curved turnout. Spike the datum rail at the far end of the turnout and then carefully align it back to the headblocks. If it will curve, I allow the rail to take up a natural curve between the two fixed points. Pin the rail to the sub-base again to hold its alignment. Then spike it to the Fig. 7 Adding wing rails. With a strip of wood helping to hold them in place, Iain solders short strips of brass under the frog to serve as attachments for the wing rails. More on our Web site See how Model Railroader’s Gordon Odegard scratchbuilt turnouts on printedcircuit-board ties. The story is online at: www.modelrailroader.com ties, but avoid placing spikes where they will obstruct the guard rails or points. I spike the outside of the rail on every tie in these locations and glue the rail to the spikes with cyanoacrylate adhesive. Frog With the datum stock rail located, the next job is to build the frog. Start by filing two rails to form the vee of the frog as shown in fig. 5. The aim is to get a nice, snug fit between them to give a crisp, sharp-pointed angle appropriate for the turnout. When shaping the taper of the frog rails, it doesn’t hurt to file away a bit too much inside the angle, as you can easily open up the gap by a tad and fill it with solder. But if you don’t file a fine enough taper, the frog rails won’t meet at a sharp-enough angle, and then you’ll have problems. I like to cut the two frog rails long enough to allow for adjustment of their exact position. You can trim them to the final length after everything is finally spiked down. Once the frog rail nearest the datum stock rail is filed sharp enough, lay it in place with track gauges from the stock rail to hold its position, as in fig. 6. Then lay in the other frog rail and adjust its angle by eye, or maybe with the help of a straightedge to pick up alignments from track already laid. Once the angle is set, spike the frog rails to the ties, and solder them together using a small iron and paste flux – rosin flux only, never acid, since Track in the street Where track will be paved over in a street, Iain builds with only printed-circuit-board (PCB) ties supporting the rail. He built this turnout essentially the same way as he does on wooden ties, but the rails are soldered rather than spiked in place and no extra brass strips are necessary. The top foil surface of every tie must be carefully cut for two-rail insulation. – Andy Sperandeo trackwork must carry electrical current. Allow the solder to flow into and fill any gaps between the two rails of the frog. At this stage, I also solder a short length of brass strip under the two frog rails, about 1⁄8" back from the nose of the frog. As shown in fig. 7, these are used to attach the wing rails and to bond the whole frog into one electrical unit. Another good approach is to use printed-circuit-board (PCB) ties rather than wooden at this location, so all the rails can be soldered into a strong and reliable unit. The Proto:87 and NMRA Fig. 8 Wing rail alignment. Sighting along the wing and frog rails is the best way to make sure they’re aligned. Iain uses a small mirror for sighting where it isn’t convenient to standard turnouts offered by Rail Works use this system. Wing and guard rails With the frog spiked in, you have the skeleton of the turnout. Gauge the other stock rail from the frog and spike it to the ties at the heel of the turnout as you did the datum rail. Add a couple more ties to support the wing rails, and then make these. Again, cut the rails long and trim them after everything’s aligned. To get nice crisp bends for the knuckles of the wing rails, file a v-shaped nick get his eye down to the track. Rolling a truck through the frog is another good test. It should roll quietly and smoothly, and any clicks or bumps mean something is wrong.

Switch points Fig. 9 Guard rails. Iain uses a wheelset to locate the guard rails, as shown in fig. 2. The plain wood supports the brass strips he uses to secure the guard rails. in the base before tweaking the rail to the desired angle with square-jaw pliers. Check the angle by holding it tight to the frog and sighting along it – the gauge or running sides of both rails should line up perfectly. Once the wing rails are bent, file away the rail base facing the frog to allow for the correct flangeway spacing. The ends of the wing rails need a “flare” to gather flanges smoothly into the frog. Some railroads bend the tips of the wing rails outward, but others simply grind away the railhead on an angle. Positioning the wing rails is probably the trickiest part of making a turnout, and getting this right is the key to smooth running. Again, the eye is the best tool, aided by a suitable spacer, to set the width of the flangeways. In P:87, these are only .022" to .024" wide, and a piece of styrene or brass this thick will Fig. 10 Filing switch points work in lieu of a feeler gauge. I find a small mirror useful for checking alignments where I can’t get into position to sight directly along the track – see fig. 8. At this stage, I also fit the guard rails, which like the wing rails need their base filed away on the side nearest the stock rails (HO rail has an over-wide base). Gauge them from the frog (not from the adjacent stock rail), using a wheelset to position them as in fig. 9 so that they hold the wheel flanges on the same side of the frog. This “check gauge” is critical for any track standard. I aim for a clearance of between .005" and .010" between the flange and the frog. Too much won’t hurt, but not enough spells trouble. Attach the guard rails by soldering them to short pieces of brass strip soldered beneath the stock rails. This will allow you to adjust the check gauge. I lay the points and closure rails as one piece. That means that the points have to flex rather than pivot like those found in commercial turnouts. With the lighter rail sections – smaller codes – this isn’t a problem. When filing points I take care to get a nicely formed profile. Bringing the tips of the points to a truly fine taper that will close seamlessly against the stock rails is essential in P:87 – those little flanges will pick the tiniest of gaps. I file points over a hardwood block clamped in a vise. As shown in fig. 10, I file at a shallow angle along the line of the rail. To help hold the rail while filing, I cut a saw slit in the face of the block to hold the base of the rail. First I use a mill file to remove most of the metal, and then I switch to a fine second-cut file for the final shaping. I finish with abrasive papers to smooth away any file marks. To provide a firm location to the heel of the point – the location from which the point flexes – solder small pieces of brass strip beneath the stock rails as in fig. 11. This is another location where a PCB tie or two might be a good idea. Cut this way Point File Hold rail here – a thumbtack works well Cross section Stock rail with base filed flush with head on gauge side Vise Saw cut for base of rail Hardwood block Fig. 11 Heel anchors. Small brass strips soldered to the undersides of the stock rails provide secure anchors for the heels of the switch points, where the rails will be allowed to flex as the points move. Trim the closure rails and wing rails to allow for an insulating gap between them, then spike the closure rails using three-point gauges to gauge them from the opposing stock rails as in fig. 12. Once the closure rails are spiked in place, the heel of the switch points is soldered to the brass strip or PCB tie. This not only anchors it in place, it makes a positive electrical connection so dirt or other foreign matter between the tip of the point and the stock rail can’t interrupt electrical power. Crossing Switch rod The last job is to add the switch rod. Make this from PCB tie strip filed to fit easily between the headblocks and with a gap cut through the upper foil surface for insulation. Solder the points to the switch rod as shown in fig. 13. This is easier if you remember to tin the underside of the point before spiking the point-closure rail. Adjust this joint, reheating if necessary, so the points close tightly against the stock rails. For P:87, the clearance between the stock rail and the open switch point is around 1⁄16". I use a spare tie as a gauge for this. It’s okay if the backs of wheels brush the open point, since it will always have the same electrical polarity as the stock rail. At this stage I like to test the completed turnout, first with just a single freight-car truck, and then with a variety of rolling stock. Make any adjustments required for smooth passage through both legs of the turnout in either direction. Once all is well, the turnout is ready for ballasting and a point-operating mechanism. I’ll go on with turnout control next month, along with wiring so you can start running trains. MR A crossing or “diamond” includes four frogs with matching guard rails. This sequence of photos shows the construction of the diamond where the pier track crosses the boatyard track. We’ll show the wiring for this all-rail crossing next month. – A. S. Fig. 12 Point-closure rails. Gauges from the opposite stock rail help Iain locate the first point-closure rail. The toe of the point fits into the housing on the stock rail, and Iain leaves an insulating gap between the closure and wing rails. Fig. 13 Switch rod. Iain solders the switch points to a length of PCB tie stock filed to slide easily between the headblocks. The cuts through the upper foil surface provide the required two-rail insulation. A small layout you can build Roque Bluffs, wiring and Simple wiring and detailed scenery bring our seaport to life W ith the benchwork, track, and turnouts completed on my HO scale Roque Bluffs project railroad, it’s time to bring this layout to life. This month I’ll describe a simple manual turnout control, install the layout wiring, and get started on the scenery. By Iain Rice Building manual turnout controls Photos by the author I designed this shelf layout for standing operation with a handheld cab control, and my experience with similar layouts has convinced me that manual turnout control works just fine on a narrow railroad like this. Roque Bluffs is built with Proto:87 (P:87) HO wheel and track dimensions, although it could just as easily be built using the National Model Railroad Association’s standards for HO scale. Proto:87 turnouts differ from normal HO turnouts in that the point clearance (the distance between an open point and the adjacent stock rail) is much narrower – around 1⁄16" – so the turnout throw mechanism must operate in a very small range of motion. However, the simple manual turnout controls on Roque Bluffs can be used for both P:87 and standard turnouts. PART 6 scenery For my wire-in-tube system, shown in fig. 1, I used K&S no. 1143 1⁄16" brass tube. I also used K&S no. 501 1⁄32" (.032") music wire to slide in the tube. Music wire is springy and it can be soldered, but it doesn’t like sharp turns. To prevent the tube from pinching closed when making a gradual bend, I always form the tube to shape with the operating wire in place. To trim the tube to length, I make a deep nick in one side with a needle file, snap off the surplus, and file the end square. You’ll flatten the tube if you use snips or cutters, but a cut-off disk in a motor tool works fine – just be sure to wear eye protection. I secured the tube by soldering it to brass pins driven into the baseboard. At the operating knob end, I passed the free end of the tube through a 1⁄16" hole drilled in a small block of wood. Because I installed all the manual actuators before I glued the Masonite fascia in place, I was careful to locate the wood block and tube a little way inward from the fascia position to allow room for the knobs. I also created a simple “friction lock” at this end of the tube by bending the tube slightly, which Framed by seaweed and the yellowed grass of late fall, a Maine Central U18B idles on a wooden trestle in the Maine seaport town of Roque Bluffs. This month, Iain Rice explains how he wired the track and created scenery for his HO scale project layout. held the wire stiffly enough to keep the switch points firmly in place. I purchased the knobs at a hardware store. The hard-plastic knobs are tapped to accept a mounting screw, so I drilled a 1⁄32" hole through the screw to accept the end of the operating wire, which I soldered in place. This allowed me to on the top surface of the baseboard. Removable scenic pieces hide the wires, and critical parts like microswitches and electrical junctions are all accessible. All the wiring leads to two compact printed-circuit board terminal strips – one for each of Roque Bluff’s baseboard sections. The terminals are inside the lean-to and office of the boatyard, a structure that spans both layout boards. The track is divided into four main electrical blocks because it’s a lot easier to locate a short circuit if you can switch off blocks until it goes away. Then you know that the last block you turned off is the one with the problem. In wiring the diamond, I took advantage of the fact that the frogs of the diamond must have the same polarity as the frogs of the two adjoining turnouts. I simply wired together these turnout and crossing frogs as shown in fig. 3. When the turnouts are set to cross the diamond, the polarity of the diamond will also be correct. I have to ensure that both turnouts are correctly aligned – even the one the train won’t be using. But this is no worse than having to flip a switch, and it saves a lot of wiring. Iain uses a simple push rod soldered to the turnout switch rod to operate the lever-action microswitch that changes the polarity of the frog. unscrew the knobs from the operating wire to facilitate the fascia’s installation – removable knobs are also much less vulnerable to damage when the layout is transported. I then fed the wire through the tube and trimmed it to length using flushcutters with hardened jaws – music wire will easily chew bites in the jaws of ordinary wire cutters. I aligned the other end of the wire to match the height of the switch rod and made sure that it was exactly in line with the rod. The push-pull action of the music wire needs to be absolutely straight to avoid twisting the switch rod. I then soldered the wire to the switch rod. I regard powered turnout frogs as essential. I supplied power to the frog through lever-action SPDT (single-pole double-throw) microswitches to change the polarity. These switches are available from electronics suppliers like Radio Shack. The best switches must be small enough to be easily concealed above the baseboard, where they can be operated by a simple push-rod off the end of the switch rod – usually the end opposite the connection to the actuating wire. The microswitches on Roque Bluffs are all located inside structures or hidden by small removable scenic details. The same microswitches can be used with powered turnouts. Basic block wiring I used a very simple wiring arrangement, shown in fig. 2. I ran all my wires FIG. 1 Manual turnout control K&S no. 501 1⁄32" (.032") music wire K&S no. 1143 1⁄16" brass tube Scenery with character I wanted to capture the atmosphere of a working port, a place where the picturesque has to contend with the practical. True, there are some characterfilled old buildings like the boatyard and a lighthouse. But Roque Bluffs also features brick and sheet-metal structures, sheet-steel piling, rip-rap fill, and lots of poured concrete. Apart from the built-up dockside, what’s left is bare rock – pale, flat-lying granite with pronounced horizontal strata and some frost-shattered outcrops – and a few patches of scrubby brush. Vegetation is confined to coarse sea-withered grass and a few hardy shrubs, wind-sheared to the odd, flattopped shape of coastal growth. Switch rod Gaps in foil Push rod for microswitch Microswitch for frog Masonite fascia Hot-glue bead Hole drilled on angle in track base Friction-lock kink Plastic knob 1⁄2" locating block Washer soldered on each side to locate tube Illustrations by Rick Johnson Landscaping with glueshell I’m firmly in the “glueshell” camp when it comes to landscape modeling. Traditional hardshell uses paper towels dipped in soupy plaster to form a thin shell layer. Glueshell is very similar, except that diluted common white glue is used instead of plaster. Glueshell has several advantages over plaster-based scenery. Glueshell is light, but also strong. It won’t chip or crack like plaster, and it’s controllable if, like me, you build up your shell with layers of tiny pieces of paper applied with a brush. You can work glueshell right up to tracks and into corners, controlling the accuracy of application by the size you tear the pieces of paper towel. Best of all, there’s no need to wait for glueshell to harden before adding texture materials, as these are held in place by the same diluted white glue used for the shell itself. I generally work in small areas – typically about 4 x 4 inches. By the time I’ve completed a small section, the section I did previously has set enough to allow scenic texturing. It’s surprising how fast you can go from bare baseboards to finished scenery with this method – and there’s nothing like the rapid appearance of finished terrain to keep your enthusiasm high. I used a heavy-duty paper towel of the type often encountered in public rest room dispensers. The towels are thick, tough, and not particularly good for drying hands, but as a landscape medium they’re perfect! Roque Bluffs doesn’t have a whole lot of topography. What little there is rests on a foundation of breakfast-cereal carton, cut into thin strips and woven into a lattice using a hot glue gun. Where necessary, I attached these strips to thicker cardstock landscape forms that I cut to the desired outline. I apply the paper towel using liberal quantities of thinned white glue and a stiff paintbrush. I start with a layer of strips cut to about 1 x 2 inches, then cover it with small pieces of towel, picking the pieces up with the tip of the brush, setting them in place, then working the glue mix into them. I think glueshell construction is a satisfying and enjoyable process. It’s also an activity you can share with younger members of your household, who will tear towels and “sploosh” glue with vigor! Rough grass and scrub The vegetation on Roque Bluffs is pretty limited, being confined to scrub grass, weeds, and brush. The basis of my “scrubland brew” is felt matting, which is widely used in upholstery and Dead-end, fed by toggle switch High level Cannery 3 4 Staging 2 Fish-meal plant FIG. 2 Wiring diagram Siding Loop (section 2) 1.

You can buy sheets of it from auto trim shops and upholsterer’s suppliers. The felt consists of two layers of pressed fiber on either side of a plastic net. I tease up wads of the fiber and chop the mat into narrow strips – 1⁄4" or less wide – with utility scissors. I then “crumble” these strips of fiber between my fingers to produce a coarse fluff. To round out the basic mix, I add a modest amount of Woodland Scenics fine turf – in this case, a mix of medium green and grass yellow. I also add a good sprinkling of Noch electrostatic grass flocking – dark green with a dash of light green and a good helping of Heki “winterboden” (literally, “winter ground”) – a good dun brown dead-grass flock. I adjust this mix by eye to give the subdued shade I’m after. Even here in rainy old England, most grass (especially my lawn!) is burnt pretty much to a dull yellow-brown by mid-summer, unless artificially or naturally watered. And that’s even truer of grass near the sea, where the salt-laden breezes stunt growth and cause withering. For the early fall setting of Roque Bluffs, I needed grass ranging from pale straw yellow through buff to brown, with only an undertone of green. The other main ingredient of my coarse grass mix is manila hemp – the stuff plumbers used to use for packing glands and joints. It’s a series of thin strands in a pale straw yellow that is just the thing for making tufts of withered grass. A good commercial alternative is Woodland Scenics field grass in the straw yellow and pale green shades. I selected a reasonable number of strands to make a bunch about 1⁄4" thick. I then chopped off clumps with a singleedged razor blade and “planted” them into blobs of thick white glue. When the glue started to set, I lightly fanned the clumps out. I then built the rest of the grass areas clump by clump using my fiber-flock-ground foam mix, applied with my fingers or a pair of ordinary eyebrow tweezers. It may sound tedious and slow, but it’s a process I enjoy, secure in the knowledge that this is one patch of grass I’ll never have to mow! I then add small bushes, weeds, and low-growing shrubs. My small, low plants are based on brown fiber teased into small balls and set into dabs of white glue with the tweezers. A quick blast of cheap hair spray and a sprinkling of suitably colored ground foam provides foliage. I create stouter growth by using either rubberized horsehair – another traditional upholstery material – or torn-up pieces of kitchen scouring or floor-polisher pad, mixed with tiny bits of natural growth (roots, mostly) harvested from my garden. I use Woodland Scenics or Heki foliage matting to create the leaves. To ensure that all the various materials stay put, I finish the job with a quick overall coating of hair spray. Pretty much any firm-hold hair spray will do. Cheap spray is more durable and effective for this purpose than the classier stuff, but be warned, it can Glueshell scenery in four steps 1 2 Glueshell is lighter and more flexible than plaster-based hardshell scenery.

Secure the strip lattice with adhesive from a hot-melt glue or use staples. smell a bit flowery. The smell wears off after a while, but it may be wise to make sure your wife knows what you’re doing before the lingering perfume aroma arouses unfortunate suspicions! Water, water everywhere There has probably been more written about modeling water than about any other aspect of scenic modeling. It’s something I should be expert at, given that pretty much every layout I’ve built – a dozen of ’em – has had some water on it, and several have had a lot. I’ve tried most techniques over the years and I’ve concluded that there’s no sure-fire way of hitting the bull’s-eye every time. The problem with water is that it’s almost invariably moving, while on a model it’s not (as are many things on our models, where the trains move realistically and everything else stands still). I’ve never encountered a modeled wave that looks good, so the harbor at Roque Bluffs forever basks in the calm of a still day in early fall. I started off by making a very silly mistake. I drew out the harbor features on the baseboard with a permanent felt marker, and neatly hatched the areas that were to become water. This proved to be a Very Bad Idea. I discovered that permanent marker shows through any number of layers of paint and varnish. I finally had to scrape the paint and varnish from the harbor area, then used spray carpet adhesive and heavy paper to cover the stripes. I then brushed on hobby acrylics in a dark green-blue-gray shade with an undertone of brown. When the paint was dry, I covered the paper with lots of thin coats of clear gloss varnish. The more coats of varnish I put on, the better it looked. Iain found that realistic stone seawalls can be created from blocks of balsa soaked in varying shades of gray paint and set in a fine bead of white glue. Block-by-block seawalls Seawalls of rectangular blocks of granite are a signature feature of a New England seaport. After a few experiments, I hit on a simple way of modeling these distinctive walls. The granite blocks normally used are roughly squared off without being finished. After trying blocks made from plaster (realistic but slow) or modeling clay (even slower), I found that blocks cut randomly from 1⁄4"-square balsa and stained with acrylic paint looked almost as good and were very quick to produce. By cutting my blocks with a utility knife with an older (not too sharp) blade I obtained a somewhat ragged cut, and by taking care not to get the ends too square and crisp, I could rapidly make irregular-looking “stones.” I colored the blocks with diluted acrylic paint, using a mix of white, gray, matte earth, and oxide red to give the warm brown-gray tones of the New England granite. I mixed small batches of paint in a deep glass jar, added the blocks, and stirred. I kept adding blocks until the paint mixture was absorbed, then tipped the blocks out onto paper towels to dry. I built the walls against a backing of thick cardstock secured in place with hot glue. Each course of stones was laid onto a fine bead of white glue. I split some stones lengthways to give halfheight blocks and set a few shorter blocks on end. I also found that the soft balsa could be squeezed or crushed to alter the shapes of the blocks, making it easy to get things to fit. Not all the seawalls at Roque Bluffs are this picturesque, however, and the stone has been replaced at various places by more modern forms of sea defense – poured concrete, steel sheet 3 4 Cover with small, torn pieces of paper towel, coarse heavyduty towels are best. Liberally brush on diluted common white household glue. The same technique is used for roads. There’s no need to wait for the glueshell to dry before adding foliage. A final dusting of cheap hair spray helps keep the vegetation in place. piling, and rip-rap fill. I made the sheet steel piling from sections of styrene Pikestuff box-profile sheet material. I then trimmed the top edge of the panels to an irregular outline (to suggest individual sheets) and glued them in place. I built the poured concrete areas using layers of thick cardstock and hot glue, and brushed on a coat of thinned tile grout to convey the look of concrete. The rip-rap is made from acrylic paintstained cat litter laid onto a glueshell sub-base using liberal quantities of thinned white glue. Rubber molds for a rocky coast Maine is a rocky state. I used plaster of paris and Woodland Scenics C1234 Random Rock and C1242 Washed Rock flexible molds to make my Maine rocks. Rather than casting my rock in place, I persuaded my daughter Bryony that she wanted to spend a Sunday afternoon mass-producing plaster rock castings – castings which Daddy then smashed up, carved, and rejoined to slowly create the rocky shore. I used white glue to bind the rockwork together and blended a soupy plaster mix into the gaps. A little sand and some cat litter served for added texture and rock fragments. I painted the rocks with matte acrylics, starting with a base coat of a mid-gray-brown followed by a wash of dilute dark gray, which I allowed to settle in crevices and beneath overhangs. I finished with drybrushed highlights in a sequence of pale granite grays, the last one being almost white. All the seawalls, piles, trestle bents, and rocks around the harbor have a broad stripe of green-brown wash just above water level to suggest the hightide mark. I applied this, using thinned acrylic paint, with a wide brush to get a consistent high-tide line. Cardstock roadways and docksides There are extensive areas where tracks are set in concrete and blacktop paving at Roque Bluffs. I established the foundation for my roads from cardstock, using thick corrugated material to build up the level between tracks. Thinner cardstock fills in between this and the railheads outside the rails, and over the ties between the rails. For reliable operation and easy track cleaning, I made sure the railheads were slightly higher than the road by finishing my card sub-base about 1⁄32" below the railheads and building up the surface with layers of paper towels. I used a hot-glue gun to set the cardstock firmly in place, paying special attention to the edges to make sure it wouldn’t curl when I painted on the thinned white glue used to fix the tornpaper road surface. Suitably slimy seaweed All seaside structures are affected by the harsh maritime environment, which causes rust on steel, pitting on concrete, and water staining, seaweed, and algae growth on just about everything that comes into direct contact with seawater. The rust, pitting, and flaking paint can be represented by normal scenic distressing and weathering techniques, but creating realistic seaweed is a whole other can of worms. I found an inexhaustible source of seaweed in my garden pond, which produces alarming quantities of stringy green slime. I dried some slime with a paper towel and chopped it into 1⁄4" to 1⁄2" lengths with a sharp hobby knife. I then picked up a few strands on the tip of a brush and draped the stuff over rocks, stonework, pier timbers, piles, rip-rap, and elsewhere on the shoreline to great effect. I added a few drops of thinned white glue to hold it all in place, but the stuff is pretty much self-adhesive. Other sea-fringe details include several clusters of clams and mussels made from Woodland Scenics fine ballast – dark gray with a touch of brown and light gray added to vary the colors. The clams cling to rocks and piers at the high-water mark. I secured them with white glue and gave them a coat of varnish using clear acrylic. To finish off the shoreline, I brushed an algae mixture – made from groundup green, yellow, and orange artist’s pastels – onto the rocks, rip-rap, and timbers, and held the pastel powder in place with more hair spray. There’s a lot of hair spray on Roque Bluffs! Next month With the basic landscape and road paving in place, I can move on to creating the buildings and a small but varied fleet of boats – the real heart of a seaport model like this.

Most of the buildings on the railroad are made from plastic kits or bits of kits, but I used scale lumber to scratchbuild two structures, and I built one craftsman-style kit as well. Tricks to improve plastic kits Most of the structures on Roque Bluffs, including the fish-meal plant and the cannery, are heavily modified plastic kits. I made the fish-meal plant from styrene panels – Pikestuff’s Milton A. Corp. factory kit is an economical way of obtaining a good supply of components. I still have a lot of parts left even after building the plant and warehouse! The “Tylick’s Soup” cannery started as Walthers’ Golden State fruit cannery. The plastic kits I used on Roque Bluffs are pretty good, but they have quirks that I find hard to live with, including visible corner joints, chunky details, and door moldings that are much too thick. The window frames and sash are also too thick, and the glazing is set too far back in relation to the framing. Happily, improving the windows is a simple task. I first thin the castings by about half their thickness by rubbing them – back PART 7 Occasionally, even after I’ve thinned them, I find that the mullions still look too heavy, so I use a small, square needle file to narrow the mullions further. This is laborious but worth the effort. On sliding-sash windows, like those on the cannery building, the instructions call for the window glazing to be glued to the rear of the window frame. However, a major characteristic of sash windows is that the glass in the upper sash is further forward than that in the lower sash. It’s a feature worth representing. I cut glazing panels from Evergreen clear styrene, insert the top ones in front of the window molding, and put the lower ones in behind the molding. Doorways, handrails, steps, sills, and cornices are some of the other details that benefit from extra work. Kit manufacturers simplify these parts to ease toolmaking. I find that adding extra trim in the form of thin styrene strip makes a big difference. Molded handrails can be a little clunky, and I often replace these with soldered brass wire or strip, which looks better and is much more robust. I’ve also found that doorways are too tall on many kits. By re-framing them or adding steps or sills, I restore the doorways to more-realistic proportions. Where there is an obviously tapered mold draft on the end of a wall panel, I file and sand the end square, and fill the cracks and joints with fine putty. Tips for realistic bricks This month Iain Rice shares a variety of techniques he used in building the town of Roque Bluffs on his HO scale shelf layout, including the scratchbuilt pier and harbor office and the kitbashed soup cannery. side down – on a sheet of medium-grit sandpaper glued to a flat piece of board. Most plastic window castings have mold draft – the edges of the piece taper from back-to-front to aid release from the mold. Removing material from the back of the molding not only reduces the depth of the framing, it reduces the width of the mullions as well. Filing the taper of the mold square is often enough to correct the mullions. Since all of the brick structures in Roque Bluffs are from plastic kits, I was able to make the brickwork look consistent from building to building. My favorite finishing technique for brick is particularly effective on plastic. First, I gently rub the surface of the brick with medium-grit sandpaper to take away the shine of the plastic parts. Then I assemble the building so I can color the entire structure in one operation. If possible, I also set aside the windows, doors, and other details for the time being. Once the building is assembled I fill any gaps and cracks with putty, then paint the building a pale mortar color – flat white acrylic with a little added gray and flat earth. This colors the mortar in the brickwork and, in the case of buildings with molded-in windows, serves as a nice neutral priming shade. Then I color the bricks with Berol’s Karisma art pencils. The colors of these soft pencils take well on the painted surface, and by using a variety of shades I can create a nicely varied and subtle brick coloring. The Karisma product line includes several useful shades. For Iain kitbashed the fish-meal plant using a combination of Pikestuff styrene panels from the Milton A. Corp. kit. He built the structure on-site using clips, adhesive tape, and Handi-Tak to hold the pieces together for trial fitting. To finish the complex, Iain later added Rix ventilators and several components from a Con-Cor grain silo kit. bricks, I use 135 Black, 144 Terra-Cotta, 918 Orange, 941 Raw Umber, and 1033 Mineral Orange. I blend the Karisma colors by layering one over the other and, if needed, rubbing them together with my fingertip. I build up the final effect slowly with a lot of lightly applied layers, working across the brick surface with the pencil held at a 45-degree angle to the brick. I use black before applying the other colors just to pick out the odd brick here and there; when overlaid with the brick shades, the darker bricks look as if they’ve been over-fired a tad. I find this helps break up the monotony of large expanses of brick. Working with scale lumber Although I’m a fan of plastics for most structure modeling – particularly Evergreen’s superb milled siding and sections – I made the timber pier and trestle from scale lumber. My first step was to pre-color the wood by staining the pieces with dilute acrylic paint. For working with scale lumber, I highly recommend a North West Short Line Chopper. Once set, the Chopper cuts wood to a consistent length and angle every time. I determined the correct length of the piling by mocking up the deck of the pier to match the height of the rail above the water. I then used a length of scrap wood to cut a few test pieces. Once I had my settings locked in, I used the Chopper to turn out many identical parts in no time flat. The pier consists of rows of piles joined by heavy lumber cross-braces, The tug M. J. McGuirk is the largest boat in Iain’s fleet. Iain made a new hull from styrene for a Sheepscot 55foot yard tug kit, and updated the boat with a modern steel mast, radar antenna, and diesel exhaust stack. The soup cannery started as Walthers’ Golden Valley Canning Co., which Iain heavily rearranged. To turn it into a half-relief structure, Iain cut the pitched-roof main building lengthwise and used the remaining side and end panels to form a flatroofed addition. Iain wanted the cannery to be part of the background, so he deliberately kept the detailing to a minimum to avoid calling attention to the building. mostly scale 12" x 12" beams. The deck is supported by two of these beams set on top of each other. There are five of these doubled beams – one down each edge, one under each rail of the spur, and one down the center of the remaining pier decking. The pier is patterned after one I sketched near Salem, Mass., but I made my version a little sturdierlooking with closer-spaced piles to support the rail spur. The piles are in rows on 10-foot centers, spaced roughly 4 to 5 feet apart. I made sure to set piles directly beneath the beams that carry the load of the track. I assembled the pier with hot glue used very sparingly. A few Peco track nails at critical points reinforced the structure. To make sure that the bottom of the piles would remain firmly in contact with the water surface, I drove a pair of drywall screws through the center line of the pier and into the frame of the layout, using large washers under the screw heads to spread the strain. The screws can’t be seen amid all the pilings of the finished pier. The deck of the pier is 1⁄16" hard balsa. Initially, I cut lengths of stripwood and laid them board-by-board. After a while, I decided life was too short and simply attached large pieces and then scribed grooves to represent planking. Now that the pier is painted and detailed I have to look closely to tell the difference. I handlaid the spur on the pier and spiked the rail down as described in part 4 of this series. In the places where the rails are set in the board deck, I put in a tie only every now and then. The spur is laid with Micro Engineering code 55 weathered rail with the top left dull. It isn’t wired – locomotives are not allowed on the pier, so it must be switched using an idler car or two. The pier track will hold two 50-foot cars. The boats of Roque Bluffs I was looking forward to this part of the project. I have a soft spot for boats, especially the older and smaller varieties. I decided that I wanted a tug of some sort, a seagoing fishing boat, an inshore lobsterman’s boat, at least one sailboat, plus a smattering of rowboats, dories, and small motor craft. But when I browsed the Walthers’ catalog, I was surprised by just how scarce HO scale boats are in comparison with most other types of accessories. Largest and most costly of my modest selection was Sheepscot’s Snapper, a 55-foot yard tug, very much a craftsman’s kit in brass, wood, cardstock, cast plaster, and plastic. I also chose Bluejacket’s no. 300 lobster boat and no. 303 Friendship sloop, but I couldn’t find a suitable larger fishing vessel. This is why, on my model of Roque Bluffs, the fishing fleet is always at sea! I started by building the yard tug. This is more a selection of parts and some helpful suggestions as to what one might do with them than an actual kit. The plaster hull former is common to a number of Sheepscot kits, and I think the hull shape is rather too racy for a humble tug. The directions suggest the former can be altered, but I figured if I was going to that much trouble, I might as well make a new hull in styrene to a more appropriate outline – not too difficult for a waterline model like this. Building a waterline hull I started my sheet-plastic waterline hull by making its footprint from a piece of .020"-thick styrene cut to the outline of the hull at the waterline. Once the footprint was accurately cut (I made it a tad oversize and finished it with a sanding block), I cut a series of openings in it so that solvent fumes from the liquid cement used to build the rest of the hull could escape. If you trap solvent fumes in a closed structure, they can distort the styrene. I built the hull with ribs of .030" styrene, and a central spine former that determines the fore-and-aft sheer (the curving slope), the height of the deck, and the angle of the bow and stern. I used the Sheepscot cast hull as a guide for the deck sheer so that the etched deckhouse would fit. Once the frames were installed, I added .125"-square styrene strengtheners at the outer ends of the frames to support the deck. The last job in building the skeleton hull was to cement the .020" styrene sheet deck in place. I drew around the top of my waterline hull and cut two pieces of .020" styrene sheet slightly oversize, finishing to match the hull by sanding. The second deck layer is an overlay into which I later scribed the deck planking. Cutting and fitting the crosspiece that makes up the stern of the boat was my next job. I made this from .040" sheet styrene, sloped to match the inward slant of the sides of the hull with the top cut to form a gentle curve. The lighthouse is a Builders in Scale Brandt Point Light kit. Iain scratchbuilt the handrails from wire and added a weather vane. working with craftsman-style kits Nearly all the structures on my Roque Bluffs layout are made of plastic – often from kits that I’ve heavily modified – but since the layout is set in Maine, I wanted to include at least one classic New England-style craftsman structure kit. Craftsman kits typically feature a variety of materials. The Builders in Scale Brandt Point Light that anchors the right edge of my shelf layout is a good example. The kit includes a plaster base, laser-cut wood shingles, a cardstock-tube main structure, and several cast-metal details. I’m pleased with The Builders in Scale kit, but I’ve found that it pays to be selective. There is a wide disparity among craftsman-style structures. I’ve found some kits to be pretty crude. In fact, one or two I’ve seen appear to require more work than would be needed to build a similar model from scratch! On the other hand, I’ve found that a good craftsman kit, carefully built, produces a subtler and more individual model than a plastic kit. In the context of a small, dioramatype layout such as Roque Bluffs, those are important qualities, ones that justify the extra work. I’m glad I invested the time. – I. R. I used the etched deckhouse assembly pretty much as supplied in the kit. For the funnel, I used a brass tube. The wheelhouse is located on the second deck by blocks of .250"-square styrene. I felt that the Sheepscot tug was a bit old-fashioned, so I updated it by changing the detailing. I simulated a diesel conversion with a new exhaust pipe exiting inside the original funnel. I also installed welded-steel masts, a tubular foremast with a radar antenna, and forward running light. I also substituted molded-rubber tires as fenders for the cast metal tires in the kit and made a rope fender for the bow. Resin boats round out the fleet The smaller craft in the harbor are white-metal castings, together with the resin kits from Bluejacket Models. Largest of these is a classic New England lobster boat, complete with cutaway wheelhouse side and the winch and davit for lifting the lobster creels. I built it following the instructions and added a few details. The other Bluejacket kit – the Friendship sloop – was also built according to directions, with a few extra detail parts. I greatly enjoyed building these kits, and I’ve ordered more of them. Operations and finishing touches Next month I’ll put the final touches on our project railroad, including signs, figures, and vehicles. I’ll also talk about how I tuned Roque Bluffs for smooth running, and I’ll share my thoughts on operating shelf-type layouts.

We’ll also give the railroad a final tune-up, an essential step for a layout built with Proto:87 (P:87) track and wheel dimensions that are closer to scale dimensions and less forgiving than the familiar HO scale standards. Details done right I have definite views on the best way to detail a model railroad. I find that a little thought makes a big difference in a layout’s finished appearance. It’s too easy to just detail everything and create scenes that are too busy. It’s just as important to have “quiet areas” in a scene as it is to have centers of interest. I use detailing to call attention to a few carefully selected centers of interest, while leaving other areas of the scene a little bare to act as visual respite. In the case of Roque Bluffs, the key centers of interest are the areas around the fish-meal plant loading silos, the boat shed, and the pier. Further back in the scene are three less-detailed centers PART 8 and operation of interest: the diner, the oil depot, and the firehouse. I deliberately kept the center of the scene reasonably plain – there could easily have been a lot more general clutter – while the long facade of the cannery at the rear of the layout is almost bland. The fall-off in detail as the viewer’s eye moves deeper into the scene creates an illusion of distance. The layered-detail approach I find that it’s much easier to build detailing in a series of layers. It gives me time to carefully consider how my overall scene is progressing, and many of my best detailing ideas occur as I move the model toward a finished state. My first layer of detail consists of those things that have to be there to conform to the prototype: switch stands, signals, signs, utility poles, relay cabinets, grade crossing crossbucks, and fences. My second detail layer includes the things I add to suit my ideas of what the scene can be. This layer commonly includes vehicles, animals, figures, and “mini scenes” – such as a chicken pen on a farm or a building site in a city. Iain found that modeling a realistic amount of dockside clutter was one of the most enjoyable parts of the detailing process. The different floats, for example, are made from bits of wood, plastic sprue, and glass beads. The last layer I’ve christened “filigree detail.” This layer include things that can be seen only on close inspection – a man working under a truck that is propped up on cinder blocks or Grandpa in his rocking chair on the porch. Knowing how best to use this sort of detail to tell a story or even to add a A Maine Central switch engine works the dockside at Roque Bluffs, Maine. Iain uses varying levels of detail to direct the attention of viewers to the important parts of the scene and to maintain a feeling of depth on a layout that is just 18" wide. touch of visual humor to a particular scene is an art in itself. Avoiding the frozen-movement trap As with waves, waterfalls, and all other things that should be moving but aren’t, I avoid figures or animals that are in a “frozen movement.” The galloping horse perpetually stuck in midstride, the workman with his shovel half-raised, and the man running to catch the train, are all banned from my layout. Rather, I look for figures in repose – standing, leaning, sitting, lying, or otherwise in positions they could conceivably maintain for some time. In this way, their lack of movement is not immediately apparent. However, finding figures and animals at rest is easier said than done. Many HO product lines seem to be populated entirely by people leaping about and animals at full gallop. I had quite a job finding enough “in repose” figures for Roque Bluffs – not the most populous spot on the planet! In the end, I used a few figures from Noch and Life-Like, along with some of the less-frenetic Preiser and Merten figures. Modeling road vehicles is almost a hobby within a hobby, and I had a lot of fun producing a suitable selection of vehicles for Roque Bluffs. Some of these are the usual HO scale favorites from Trident, Busch, Roco, Eko, and so on, but there are also a few kitbuilt vehicles to add interest and variety. As with the figures and animals, I find that a vehicle placed in a spot where it should be moving – but obviously isn’t – strikes a jarring note. I’ve also made a point of giving my road vehicles a touch of workaday grime. The vehicle I spent the most time on is the pride of the Roque Bluffs Volunteer Fire Department – a shiny Ford pumper parked on the firehouse driveway while the members carry out a little remodeling project indoors. The fire truck is an Alloy Forms kit, which I modified slightly to follow a fire engine I photographed in upstate New York. Extra detail includes grab rails, lighting, and a full complement of fire hose on the bed. Alloy Forms kits call for a bit of work, but I love them. Layout tune up Any model railroad benefits from a thorough mechanical and electrical going-over before regular operation starts. On Roque Bluffs, I spent a good many hours carefully test-running all my equipment and ruthlessly investigating any derailments, hesitant running, or other operating problems. Time spent at this stage determining and correcting problems is repaid when the layout is in regular operation. Many of the problems I found had to do with the scenic work, such as ballast or ground foam blocking crossing and turnout flangeways or paint or glue residue on the railheads. I also looked for equipment flaws. As a rule of thumb, the car is suspect if it derails at more than one location, the track is suspect if different cars derail at the same location. For rolling stock, I’ve found that the chief culprit in derailments is dirty wheel treads. Those P:87 flanges are really tiny and even a small speck of crud is enough to cause a problem. I also learned that it is essential that the trucks swivel freely and that at least one truck on each car is able to rock from side-to-side and fore-and-aft to allow equalization. The close-to-scale couplers I used required careful installation – there’s no room for error with these tiny coupler knuckles. Even when the couplers are set correctly, I discovered that manual alignment of the knuckles was often necessary when coupling cars, but that’s also true on a real railroad. To my surprise, Roque Bluffs proved more finicky to operate than an earlier P:87 layout I’d built that used Europeanprototype rolling stock. I believe that the U.S. combination of long cars with short-wheelbase trucks has a bearing on this – my big covered hoppers are certainly more susceptible to track faults than are my 40-foot boxcars. I’m sure that a really free-acting equalized truck with minimal slop in the wheel bearings Meet Iain Rice Iain Rice has written articles and books on model railroading for more than three decades, but Roque Bluffs is his first multi-part layout project. Iain wishes to thank his wife Rosalind and daughters Elsa and Bryony, and friends John Chambers, Andrew Boyd, and Marty McGuirk. He also acknowledges the assistance of Martha Sharp at Train and Trooper in North Yarmouth, Maine, who came up with most of the bits and pieces (often at short notice), and the helpful staffs of Terminal Hobby Shop in Milwaukee, Des Plaines Hobbies in Chicago, and Henry’s Hobby House in West Boylston, Mass. Iain, a professional firefighter, lives in Chagford, England. The vehicles on Iain’s layout are parked rather than positioned on the road, and the figures are limited to poses that they could conceivably maintain for some time. This makes their lack of motion less distracting. would go a long way to ensuring reliable contact between wheels and rails. Operating a shelf-type layout Roque Bluffs is a pure switching puzzle, and that’s the only practical form of operation. Short trains, usually four or five cars, are brought into the yard from staging. All the cars have different final destinations on the layout. Delivering them is not a simple proposition. The oil depot and the pier spurs face one way, the fish-meal plant spur faces the other, and the cannery spur is reached with a reverse move. The other difference from normal operating practice stems from the use of narrow P:87 wheel and flangeway dimensions and fine-scale couplers. Working with these more-exacting components gave me a new appreciation for the forgiving nature of standard HO! I find that switching Roque Bluffs is a much slower and more demanding process than switching a normal HO layout and, in terms of authenticity, that’s also closer to real-life. Switching is often labor-intensive and time-consuming, which is why real railroads regard it as a necessary evil and model railroaders think it’s fun. Would I do it again? Roque Bluffs is now in the shakedown phase. I’m still making all sorts of little improvements, and every week the layout looks and runs just a tad better. I have no doubt that P:87 dimensions work well, but I also know that this is true only because I put in the time and effort necessary to achieve the required accuracy in the trackwork and equipment. A lot goes into keeping those tiny flanges on the rails! For that reason I don’t see P:87 as a realistic option for everyone. I certainly wouldn’t care to attempt a large P:87 project. But in the context of a small layout, I believe the better appearance of the narrower wheel and flangeway dimensions are well worth the effort. My conclusion is that there’s definitely a place in the hobby for track, wheel, and coupler dimensions that are closer to scale than ordinary HO, while being less demanding than true-scale P:87 dimensions. I may have a few ideas to try on my next layout! MR The narrow width of the Proto:87 wheels used on Iain’s Roque Bluffs layout look realistic but make it difficult to rerail cars. Iain made this simple ramp from thin brass sheet and soldered wire to solve the problem.

I found the perfect candidate in the MEC’s “Independence class” U18B lightweight road switchers. Built by General Electric in 1975, each of the ten locomotives was named for people or events associated with the United States’ Bicentennial celebration. However, as no one manufactures this distinctive engine, the only way I was going to get one would be through cutting and splicing. sill that hold the shell to the frame. Again, consult the cutting diagram for this detail. On the finished model, the body simply press-fits to the frame, so keep in mind that it’ll be safer to pick up the locomotive by its fuel tank. One other major shell modification reversed the short door and air filter under the inboard end of the radiator compartment, both of which are molded the “wrong way up” for a U18B. To make the correction, follow the cutting and reassembly directions in fig. 1. I also changed a number of molded-on cab and nose details on the locomotive as shown in fig. 2. Reworking the shell and frame My model Independence class U18B no. 403, the General Peleg Wadsworth (couldn’t resist him!), started life as an Athearn U30B. To shorten the shell and frame follow the cutting diagram on page 93. [For a step-by-step description of how to shorten and power the Athearn model, see Dean Foster’s article “Kitbashing a GE U18B” from the March 1984 issue of MR. You can find a reprinted copy of it on the modelrailroader.com Web site. – Ed.] You can make all the other indicated shell revisions at this time as well, including removing the latches on the side Coupler mounts Another unique GE U-boat feature is the coupler box, which extends part way through the face of the pilot. Figure 3 shows the pilot with the new coupler boxes installed. I started by shortening Kadee no. 5 coupler boxes to hold no. 58 scale-sized couplers. After sawing the cast-on coupler mounts from the frame, I built new coupler mounting pads behind each pilot on the shell using .250"-square styrene with .040" styrene height-adjusting spacers. Next, I attached the couplers and boxes to the pads with self-tapping screws.

Photographs of Maine Central U18Bs show that the bell was mounted on the long hood behind the cab on the fireman’s side (he must have felt like Quasimodo after a trip over Crawford Notch!). I made a styrene strip bracket for a Details Associates frame-mount bell (a portion of the finished bell can be seen in fig. 5). I added other detail parts to the shell as shown in fig. 3. The cab needed some basic interior details; with those big side windows, you can easily see into the cab. I cemented pieces of .250"-square styrene inside the battery boxes below the cab and built a floor from pieces of .020" styrene sheet on top of them. This arrangement clears the gear tower on the truck at maximum swing and covers the drive coupling. I made a simple control stand and seats (as seen in fig. 3) from styrene scraps. Tuning up the mechanism Mechanically, my U18B is pretty much identical to other Athearn four-axle road switchers. The only real modification I made was to replace the original trucks with Athearn’s GPtype (“Blomberg”) trucks to match those on the prototype. Because the model was for my Proto:87 layout, I used NorthWest Short Line’s no. 376424 Proto:87 conversion wheelsets as shown in fig. 4. The turned nickel-silver replacement wheels simply push into the Athearn gear sockets.

After carefully removing a number of molded details from the cab and nose, Iain sanded the parts smooth with fine-grit sandpaper. lowing the National Model Railroad Association’s (NMRA) Recommended Practice RP-4, I gauged the wheelsets to .613" measured from the back of one wheel to the rail side of its partner’s flange. After installing the wheelsets, I carefully checked that the trucks would roll freely before clipping them to the frame and hooking up the drive shaft. I added only a few details to the truck frames as seen in fig. 3. Before assembling the trucks I chemically blackened the steel side plates with a product called Gun Blue, though you could paint them black instead.

In addition to building a simple cab interior from styrene scraps, Iain also added the assortment of details seen here. This view also shows the new coupler box mounted to the pilot (the snowplow is temporarily held in place with poster adhesive). To improve electrical contact, I soldered power wires from the trucks to the motor. I also cut down the L-shaped truck contact strip at the cab end just above the engine frame to clear the detailed cab interior. Finally, I replaced the Athearn headlight with a Train Tronics constant lighting system. [If you use Digital Command Control on your layout, you will want to install a DCC decoder at this time instead of the Train Tronics circuit. – Ed.] Painting and decaling After bathing the shell in mild soapy water to wash off all of the oil and dust from handling and sanding, I primed it with Floquil Gray Primer from a spray can. After the primer dried, I airbrushed the shell with Polly Scale MEC Harvest Gold (I add a dash of Polly Scale Clear Gloss to the paint). I then masked the model and airbrushed the cab roof and long- and short-hood tops Polly Scale Pine Green. I brush-painted the side sills and frame with Humbrol Matte Black paint, masking the straight edges. Next I used a spray can to paint the frame and fuel tank Floquil Engine Black. I then brush-painted the truck frames and details in a weathered black I mixed myself from Humbrol paints, including Matte Black with a dash of Matte Dark Earth and a spot of Silver. After the paint had completely dried, I decaled the locomotive with Accu-Cals set 5807. (For the pilot, however, I used the white stripes from Microscale set 4181.) Once all the decals were in place and safely snugged down with a touch of Micro-Set, I sealed the decals in place with an airbrushed coat of Micro Satin finish. Final detailing and weathering With the painting and decaling out of the way, it was time to add the final details. To glaze the cab windows, I used clear plastic cut from a Ferrero Rocher chocolate box, carefully filing the pieces to size. Laser-cut glazing from American Model Builders would be a lot easier to use (except you don’t get to eat the chocolates). Figure 5 shows many of the other details I added, as well as the chalk weathering I applied to the finished model. I weathered the engine lightly as I wanted the locomotive to look newer. The work to build this rare four-axle road switcher was time well spent; it’s nice to have an engine you won’t see on every layout, and these little snub-nose GEs certainly have a lot of character. 1 Fig. 4 INSTALLING WHEELS.

Cardboard Strip Method B een procrastinating? Sooner or later all the track is laid and wired, the trains are running, the equipment has been detailed and weathered, and you can no longer put off building scenery. Fortunately, it’s easier today than it was, say, 20 years ago, thanks to all the quality scenery products now available. You can get nearly everything you need at a well-stocked hobby shop. Remember that no stretch of scenery has to last forever. If you don’t like it, you can just knock it out and try again. (Lots of fine modelers have done just that more than once.) You’re out only a few bucks worth of materials and you’ve gained valuable experience. Like most everything else in this hobby, the more you do it, the better you get. The three elements Once we’ve modeled the ground, it’s time to paint it. Lots of modelers choose browns that are too dark. Soils are lighter than we think, plus our layout lighting doesn’t approach the intensity of sunlight. Medium tan in a flat latex wall paint works very well for model railroad scenery. Usually we thin the latex paint about 50-50 with water, brush it on, and then begin sprinkling scenery materials on immediately to take advantage of the paint’s adhesive quality. We can Advantages Disadvantages 1. Inexpensive (particularly with messy methods). 1. Need carefully applied finish layer to hide outline of strips. 2. Fast (particularly on broad expanses). 3. Easily modified. 4. Lightweight (particularly if Sculptamold is used). 2. Smooth surface with hot-wire tool, knives, Surform tools, whatever works. (Hint: Hot-wire tools are great.) That’s it. You’re ready to paint the surface with tan latex paint. 2. May need modifications to obtain final shape desired. 3. Messy (unless plaster cloth and Sculptamold are used). Advantages 1. Controllable, easy to achieve the shape you want. 2. Lightweight and quite durable (especially good for modules and portable layouts). y ; y ; y ; y ; y;y; As my friend Bob Hayden says, there are three elements of scenery-making: form, color, and texture. Get all three right and your scenery will be right. Let’s start with form, the shapes of things. Your best friend here is observation. Our memories don’t serve us well; looking at the real thing and studying photos is much more reliable. After considerable squinting and hand waving over imaginary contours you’re ready to start. Figure 1 shows two popular techniques; I’ve listed some advantages and disadvantages with each. Modeling with extruded foam board is extremely popular with today’s modelers, so if you have difficulty choosing, choose that. Cut strips across the corrugations. Color and texture 1.

Fig. 3 COLORING ROCK CASTINGS To unify a rock surface apply plaster between castings and use a knife to carve the wet plaster so it blends with the castings. (A palette knife works best for me.) Painting rocks Most modelers use artist’s acrylics, usually out of tubes. They dry quickly and clean up with soap and water. (You’ll note that the materials we’ve discussed here are all water-soluble. Generally this means you can keep working without waiting for work to dry thoroughly, can clean up easily, and won’t get chemical reactions.) When painting rocks I begin with a thinned coat of white, but many modelers go straight to work with colors. For the most part we stick with earth tones: burnt umber, raw umber, burnt sienna, and raw sienna. Of these burnt umber (a rich brown) is the most useful. You’ll also need some Titanium White and Mars Black to lighten or darken colors. Squeeze out short ribbons of paint on a palette, a white dish, or whatever is handy (as long as it’s white so you can see the colors). Keep a cup of clean water handy (change it frequently), and start mixing with your brush and painting. This may sound artsy and difficult, but you’ll get the hang of it quickly. Washes and drybrushing 1. Paint rocks with acrylic paints, let dry. 2. Flow on black wash with wide brush, let dry. sprinkle on sifted real dirt, tiny rocks, ground-up leaves, or kitty litter, but the favorite material today is ground foam.

Lightly drybush to highlight surface detail. Don’t overdo it. als. Otherwise you can end up with a crust that breaks away, revealing still loose materials underneath. For small areas spray on “wet” water (water with liquid detergent added), then apply the adhesive (mixed the same as for spraying) with an eyedropper. Rocks Bonding scenery materials As you build up scenery materials you can bond them in place by spraying them with a dilute mixture of adhesive from a household plant sprayer, as shown in fig. 2. (Clean the sprayer afterward if you expect to be able to use it again.) I like to use matte medium, an acrylic varnish available from art supply stores. A good ratio for spraying is 5 parts water to 1 part matte medium. Adding about a half-teaspoon of liquid dishwashing detergent will help the adhesive penetrate the scenery materi- Lots of modelers carve rocks in plaster as it is setting up and some get good results. For the rest of us a better, faster method is to cast rocks in rubber molds, available at hobby shops. Plaster of paris, patching plaster, and molding plaster all work well for casting rocks. Just mix the plaster to a thick cream consistency and pour it in the molds. Either let the castings set up in the molds, then glue them to the layout, or else keep an eye on them and as they’re setting hold them in place on the layout to cast rocks in place. Several special painting techniques will prove helpful. The first is washes, wherein you flood an area with a thin solution of paint, applying it with a large brush, say a 1" or 11⁄2" flat. See fig. 3. Besides being good for establishing a color base, this technique is also useful later in the painting process. You can, for example, apply a thin coat of dark color that will settle into nooks and crannies and help bring out the detail. Another technique is drybrushing, wherein you dip the brush into paint, wipe it dry on a paper towel, then brush vertically over raised surfaces. (Yes, an all but imperceptible amount of paint has remained on the brush.) A 1⁄2" flat brush works well for this. All I’ve attempted here is to touch on some primary concepts, techniques, and materials. For a wealth of further information, get Dave Frary’s book, How to build realistic model railroad scenery, published by Kalmbach. Give scenery modeling a try. It’ll make a tremendous difference on your layout, and if you don’t believe me, just sprinkle some green ground foam on a stretch of plywood next to the track and run a train by. What a difference! 1 BUILD REALISTIC H ighly detailed, prize-winning foreground scenery doesn’t have to be time-consuming or overly complex. In fact, with a little effort and research, building show-quality scenery can be fun, easy, and rewarding. My scenery techniques were inspired by a convention clinic given by late MODEL RAILROADER staff member Art Curren in the 1990s called “Scenery as I See It.” The main point of Art’s clinic was that density, shape, size, and color vary greatly in nature. As a result, the more texture you can add to your scenic details such as trees, brush, and undergrowth, the more realistic they’ll appear to the viewer. Follow along as I take you step-by-step through the process I used to build the scenery for my HO scale model contest dio- The scenery techniques Sam Swanson uses on his HO scale layout and award-winning dioramas are fun, convincing, and most importantly, simple to duplicate for your own model railroad. rama, Hall Hollow. It is an Appalachian valley coal mine surrounded by muddy roads, dense brush, rock outcroppings, and wooded hills, adding realistic texture to the scene. 1 Sam Swanson, of Cincinnati, Ohio, enjoys scratchbuilding highly detailed structures. Having won many awards for his modeling work, his Hall Hollow diorama, as seen in this article, won first place for On-line Display at the 2001 National Model Railroad Association convention in St. Louis, Mo. SCENERY 1 Landscaping from the foam up By Sam Swanson • Photos by the author A SOLID YET FLEXIBLE BASE For a solid foundation I use extruded foam insulation board. I build the rough topography by stacking layers of foam, holding them together with Liquid Nails for Projects adhesive and bamboo skewers. After the glue dries, the land features are easy to define using a serrated-edge paring knife. Other tools that work well for shaping the foam include a Surform tool, a rasp, various wire brushes, and even sandpaper. (A Shop-Vac is also a handy item to help control the mess.) Next, I pencil in roads and trackwork with a permanent marker, and cut spaces for structure bases that will be incorporated into the scene. 2 ROADS AND TRACKS WITH PURPOSE I use track spurs and roads as leading lines to guide viewers into a scene. Typically the lines provide a color contrast – dark-ballasted rights-of-way versus light clay roads – and each helps catch the viewer’s eye. For rail spurs, I glue flextrack into place with a thin layer of Liquid Nails spread on top of the foam roadbed. I then spread soil and ballast around the track and secure it with diluted white glue (two parts water, one part glue). For dirt roads, I mix fine clay soil with diluted white glue to a consistency of peanut butter as seen in the photo on the right. Then I spread it on the roadway about 1⁄8" thick and work in ruts with the end of a paintbrush. Next I sprinkle dry clay on the non-rutted areas and let the road dry thoroughly. For the final touch, I rub the road with a stiff brush or my finger to give it that dusty, hard-packed clay road appearance as seen in the photo below. 3 EASY ROCK OUTCROPPINGS The bulk of the outcroppings on the diorama are carved from the same foam insulation board I used for the base. I score and snap 2"-thick foam pieces and glue them in place to start the rock formations. I then carve and sand the outcroppings until I am satisfied with the lines and shapes of the rocks. Next, I use a four-step finishing system, as shown in the photo. First I paint the outcropping with a suitable tan color. In the second step, I stain crevices and shadowed areas with a thinned complementary dark color of paint. For the third step, I add texture to the rocks by what I call the “soiling” process: affixing fine clay to the rocks with diluted white glue. I brush diluted glue over the painted/stained (and thoroughly dried) surface. Then I sprinkle or brush the clay liberally on the rock face and let it dry completely before proceeding. As a final step, I drybrush the rocks with lighter colors of paint to highlight and accentuate the texture. 4 BLENDED GROUND COVER To give the ground the proper look, I use an assortment of soils, rock debris, and ground foam to create my basic ground cover. For your layout, consulting pictures of the area you are modeling is a must when making these color selections. I start by painting the open foam areas between the track, roads, and rock outcroppings with a flat interior latex tan paint. I then add soil and fine ground foam, along with talus (rocks sloughed from outcroppings) around the rocks. To vary the soil color, I use two strengths of diluted white glue: The stronger the glue mixture, the darker the color of the soil when it dries. For the area I model, foam colors include a variety of greens, browns, and yellows. I commonly use eight different colors, starting with Woodland Scenics Green and Earth blends. I let the ground cover dry thoroughly before adding any other scenic details. 5 FUZZY UNDERBRUSH I consider everything from grass tufts, bushes, brier thickets, and weed accumulations to be underbrush. The two materials best suited to modeling underbrush are jute twine for grass and commercial poly fiber for bushes and thickets. They have the “fuzzy quality” that Art Curren stressed as important in model scenery and simulate the dense undergrowth found throughout my modeled region, the Appalachian hills. To create large areas of thicket and weed underbrush quickly, I use thinly stretched mats of poly fiber covered with several different colors of fine ground foam fixed in place with either maximum-hold hair spray or Testor’s Dullcote. I use the same colors as the ground cover and prepare a variety of color combinations, often placing different colors on the front and back of the mats. To make wildflowers, I add dashes of Woodland Scenics no. 48 flower mix to a few of the poly fiber mats. When installing them in the scene, I vary the underbrush mats by mixing up the colors, shapes, and densities. I stretch the mat so some of the ground cover shows through and glue it in place with beads of fullstrength white glue. 6 TUFTS, BUSHES, AND SAPLINGS With the poly fiber underbrush in place, I add more detailed individual underbrush items including grass tufts, bushes, and saplings. For grass tufts, I stain and tease jute twine. When dry, I plant the tufts in holes in the foam base and secure them with white glue. You can also use grass tufts to make small bushes by gluing fine foam to the jute fibers for leaves. I make simple bushes from poly fiber or tree foliage balls sprinkled with fine foam. I typically use bushes in heavy undergrowth areas to provide some vertical shapes and vary the texture of the underbrush. For saplings I use the small twigs that break off when making trees and top them with a ball of commercial fiber or clump foliage; both work well and provide variety through color and density. I use saplings to bridge the transition from underbrush to the wooded areas, much as they do in nature. 8 LEAVES FOR YOUR TREES To add leaves to the trees, I use Woodland Scenics fiber and clump (or cluster) foliage. The key to making realistic trees is to cover the sunflower and twig branches with many small puffballs of teased foliage material individually glued to the branches. I start near the bottom of the tree and work out and up along the trunk and branches, gluing the foliage balls on with white glue. After those have had time to set, I fill in any unwanted open spaces by gluing puffballs directly to each other. When dry, I highlight the treetops by dusting them with light-colored fine ground foam, holding it in place with hair spray or Dullcote. I install the trees on the diorama last, only after all the other scenery has been completed. First I test the placement of the trees in the scene, either individually or in groups of three or five. Once I am happy with how they look, I plant each tree by pressing it firmly into the foam base, securing it with white glue. With that, your lush, textured Appalachian scenery is finished and you can to amaze your friends with your realistic re-creation. 7 TREE TRUNKS THAT LOOK RIGHT To make the dense stands of deciduous trees that characterize Appalachia, I use three different types of trunks covered with fiber and clump foliage, as well as fine ground foam. My goal is not to model specific species, but to vary trunk and foliage sizes, shapes, and colors enough to produce realistically wooded hills. For my homemade tree trunks, I use sunflower roots and various twigs. They’re realistic and free! I preserve the natural trunks by allowing them to dry thoroughly over a couple of months and then submerging them in a pool of diluted white glue. Later, I add a 3⁄8" length of .020" brass wire to the base as a mounting pin. To make larger trees, I combine sunflower roots and twigs. Sometimes I thicken the trunks by sculpting root bases from Duro Master-Mend green epoxy and then paint the roots to match the rest of the tree trunk. I also use Scenic Express SuperTree commercial kits for their light and airy appearance. Western scenery How-tos for handling the subtleties of arid scenery in foreground locations By Pat Gerstle • Photos by the author M any modelers are drawn to Western scenery: snow-capped mountain ranges, twisting canyons, endless deserts, and pine forests. I suspect some modelers even choose the location before they choose a railroad. The photo of Clear Creek Canyon, Colo., (fig. 1) is the sort of scene that inspires us to model the West, but what we usually see when standing trackside, as fig. 2 shows, is a few feet of rocky soil, some scrubby bushes, and maybe some larger rocks and a hillside behind the train. This article is about how to model this up-close-to-the-action trackside detail. Research Among my primary references for colors and general scenes are pictures from railroad wall calendars. The photos are large, very high quality, and provide a detailed view of the railroad and its surroundings. Nothing helps like the real thing, however, so I have an equally large collection of personal photographs. For general how-to on scenery, I recommend Dave Frary’s How to Build Realistic Scenery for Model Railroads from Kalmbach Publishing. Terrain In fig. 3, I have cut and glued some 2"-thick blue foam to form the base of a small rise on which a mine will be placed and covered the foam with plaster soaked towels or gauze. I then painted this base with a soupy mix of plaster to fill in any holes and thin areas. Next I added rock castings, fixing them in place with plaster and painting around them with the plaster soup to blend them into the base. Finally, without waiting for the plaster to dry, I painted the ground and castings with the base color. Western scenery is mostly beige with some light tans and reds thrown in. I use Sears no. 770 interior flat latex diluted with an equal amount of water. Brush it over everything except the rocks. On the rocks, mix one part paint with two parts water for more of a stain. Now wait for things to dry, then brush on some dilute raw umber for reddish highlights. Finish with your favorite black wash (either very thin black paint or India ink and alcohol) to bring out the details. Your finished scene should look something like fig. 3. Ground cover The next process introduces most of the surface details, and most of the surface detail in the West consists of LOTS of rocks, of all sizes, scattered and piled everywhere. I used the following Woodland Scenics products: talus (fine, medium, coarse, and extra coarse in Buff and Brown; ballast (fine and medium) in Buff and Brown; turf and coarse turf in Yellow Grass, Burnt Grass, Earth, and Soil; clump foliage in Burnt Grass, Light Green, and Fall Mix; and field grass in Natural Straw, Harvest Gold, and Light Green. I also use finely sifted dirt and goldmine tailings I gathered from the area I’m modeling. I make a palette of these materials by placing them in empty tuna cans in a box lid. Start by painting a small area (about one square foot) with a thick coat of full-strength white glue. Now drop the large talus pieces randomly and in groups over the area. If the area is sloped, place more toward the bottom. Next, drop the medium talus around, followed by the fine. Use more of the medium and lots more of the fine. Put some of the medium and fine talus around the large and randomly distribute the rest over the whole area. Concentrate the talus in gullies, stream beds, and at the base of rock formations. At this stage your scene should look like fig. 4. Fig. 2 TRACKSIDE SCENERY. At trackside, you rarely see big vistas; usually you see a relatively shallow scene of rocks and grass. Fig. 1 CLEAR CREEK CANYON. This view typifies the scenery of the West, but few layouts have the space to model such large vistas. Now scatter small patches of the turf and grass around – not a lot and concentrated in the areas where moisture would collect. To fix the groundcover, I spray on a coat of “wet water” (water with one or two drops of dish detergent added so that it soaks into the groundcover). Then I use an eyedropper to distribute a 50/50 mixture of white glue and water. Make sure the ground is thoroughly saturated with glue. Only when all is solidly dry do I plant the larger shrubs and trees. The shrubs are clump foliage and the trees are pines and aspens from K&S Scenery Products. A lot of the shrubs are placed near the larger rocks because moisture collects in the shadows. The last thing I add is the field grass – I love this stuff! I add clumps in all shapes and sizes around larger rocks and in gullies. I think by striving for realism in the area you would see up close I’ve captured the look of Western scenery without trying to include the snow-capped back range! 1 Pat Gerstle is a computer programmer who lives just outside of Lexington, Ky.

Concentrate them where water naturally collects. 7 steps to realistic ROCKS Easy scenery you can make with ceiling tile By Joe Whinnery • Photos by the author O ne of the nicest comments I’ve heard about my layout came during the 1997 National Model Railroad Association convention. Some visitors from back East said the sedimentary rock formations on my HO scale Eastern coal-hauling layout looked real, and that they knew exactly where the actual scene was I had modeled! That is the essence of model railroad scenery – making it look real. The technique I model rocks with is time-tested but perhaps new to some of you. Beside getting great results, it’s easy and inexpensive. Re-creating dramatic scenes such as this is part of the fun of building scenery. Joe Whinnery relies on a time-honored technique to make typical Appalachian rock formations for his HO scale Eastern coal-hauling layout. The Appalachian Mountains are layers of sedimentary rock that the massive collision of two continents forced upward. In some places – like this scene on Cranberry Grade at Terra Alta, W. Va. – the rock layers folded into elongated arches and troughs. Ceiling tile built up in layers, textured, and painted can re-create this dramatic effect. Ceiling tile unlimited Planning pays off I prefer ceiling tile for creating large sedimentary rock formations typical of the Appalachians. I’ve also used plaster castings with good results because the rubber molds duplicate the textures of real rock. But I’ve found most rock molds are too small to effectively and efficiently create large rock expanses. In the same vein, extruded foam board makes fine rock surfaces, but it’s more difficult to achieve the layered look I wanted. Ceiling tile has many advantages. It’s inexpensive and easy to find, cut, shape, and color. But make sure you buy new ceiling tile at a home-improvement or hardware store rather than scrounging for castaway pieces from an old building. The discarded stuff might contain asbestos – model railroading is supposed to be fun, not hazardous to your health. And always wear a dust mask when cutting and carving ceiling tile. Before grabbing my carving tools, I take some time to plan how I want the scene to look. As was mentioned in Part Four of Tony Koester’s Coal Fork Extension series (September 1998 MODEL RAILROADER), Africa and North America have probably collided at least twice in Earth’s long history, and the last collision created the Appalachian Mountains. And during one of the continents’ earlier collisions, tectonic plate action compressed many sedimentary rock layers, creating arches called “anticlines” and troughs called “synclines,” which are prevalent in the Appalachians. I wanted some sections of my scenery to reflect this signature geological effect, so I tilted some ceiling tile layers upward with a small wedge of material, such as a door shim. Got your new pieces of ceiling tile and some tools? Good, then let’s make some rocks! 1 1 TILE PIECES. Snapping pieces of tile over the edge of 2 BUILDING UP LAYERS. Stack layers of ceiling tile to a board creates a clean edge. Score the white side with a screwdriver, utility knife, or old hacksaw blade, then gently bend the tile over the board until the piece snaps off. It’s a good idea to do this step outdoors because of the dust it creates. the height you want the rock formation to be. Glue each successive layer to the one beneath it with white glue or a thin layer of an acrylic adhesive such as Liquid Nails for Projects. Weight or pin the pieces together until the glue dries. CARVING. This is the messiest part of the rock-making process, so make sure you do it outside and wear a dust mask. You can carve ceiling tile with a wire brush, a straight-slot screwdriver, and broken hacksaw blades. Use the wire brush in a long horizontal motion to get a layered look, and the screwdriver and hacksaw blade to make deep, vertical fissures. Refer to photos of real rock formations and use your imagination. PATCHING. Mix up a small batch of Sculptamold (a clay and paper product available at most hobby shops or from Walthers at www.walthers.com) and patch any significant gaps in the tile with it using a palette knife (available at most art stores and some hobby shops). The Sculptamold shows as white areas against the gray tile and, after it dries, it will take paint just as well as the ceiling tile layers. 3 4 PROJECT AT A GLANCE C eiling tile is a handy material for making easy and realistic sedimentary rock formations like those typically found in the Appalachian Mountains. Coloring the rocks is as simple as airbrushing or brush-painting earth-tone acrylic washes over the sealed surface. Tools you’ll need include: ❑ ❑ ❑ ❑ straight-slot screwdriver old hacksaw blade dust mask wire brush ❑ ❑ ❑ ❑ palette knife 2" paintbrush shop vacuum airbrush (optional) Meet Joe Whinnery J oe’s interest in railroading started in grade school when his uncle worked as a brakeman for the Baltimore & Ohio’s St. Louis Division. After a tour in the Army as a photographer, then college, Joe’s interest in model railroading revived. His current layout is an HO scale Eastern coal hauler drawing on the B&O, Chesapeake & Ohio, and the Chessie System. The 13 x 30foot layout has earned the National Model Railroad Association’s Golden Spike and Master Scenery awards, and it was one the layouts participants could visit during the 1997 NMRA convention in Madison, Wis. In addition to his career as a professional photographer, Joe works at the Brass Whistle, a hobby shop in Loves Park, Ill., near Rockford. 5 SEALING. Get rid of the “fuzzies” the wire brush caused by brushing water over the tile face. This step keeps the porous tile from soaking up too much sealer. Leftover tan-colored latex paint makes a great sealer. Let the sealer coat dry completely before applying any other colors. Tile that’s too wet can break apart. COLORING. It’s best to color your rocks under the same kind of light that’s over your layout. You can use an airbrush or brush-paint. If you brush-paint, apply thinned acrylic earth tones over faces, then spray the rocks with water to blend the colors. An airbrush lets you do more precise coloring, such as simulating a layer of shale in sandstone. You’ll get better results with several light passes of the airbrush rather than one heavy pass. 6 More on our Web site For another basic technique you can use to make realistic rocks, visit MODEL RAILROADER’S Web site at www.modelrailroader.com. There you’ll find an article on how to make rock castings. SOIL AND VEGETATION. After blending the existing scenery base around the rock face, add vegetation and soil. Kudzu, a noxious weed prevalent in the South, often covers rock faces. Finely sifted dirt or gravel gives the appearance of soil that’s been washed down the face of the rock. To simulate kudzu, make a light pass with spray glue over stretched-out brown or green polyester fiber, then sprinkle medium-grade ground foam on the fiber. 7 Splendor in the grass Modeling knee-deep grass with a new material and methods By René Gourley • Photos by the author A s a youngster I spent many quiet afternoons sitting in a trackside field about a mile from my home while the breezes rustled through the tall grass. The rails shimmered brightly in the afternoon sun while birds soared overhead and the field resounded with the sounds of summer insects. Ultimately my patience was rewarded when the blare of a distant air horn brought me to my feet so I could see the oncoming train. The tall grass along the right-of-way never saw a mower so some of the plants tickled my chin when I walked through them. Over the years, I’ve attempted a number of techniques to duplicate these high grasses in HO scale using fake fur, twine fibers, and ground foam. Unfortunately, ground foam evokes leaves and foliage better than it does tall, vertical grass, and fake fur comes on a woven backing that’s too dense. In 1998, I received a German model railroad magazine which had some superb photos of scenery with tall grass that made me look twice. The article indicated that the scenery was made using products from Silflor, a German manufacturer of scenery materials. First sample Silflor makes a variety of grass materials as shown in photo 1. My first sample was a square of winter pasture. This mat represents grass that’s been standing for some time so the leaves closest to the ground are still green, but the tall blades have been bleached by the sun. The fine nylon fibers are tightly packed, providing an excellent representation of a densely planted field of standing hay. Turning the sample over, I found the grass is woven into a backing of heavier fibers. You can pull this substrate apart to produce a scattered, irregular field of hay. See photo 2. The grass never gets 2 1 3 5 4 1. VARIETY. Silflor’s grass comes in short bristle spring, summer, and winter colors. The autumn mat has the longer bristles to simulate tall grass. Other mat colors and textures simulate forest ground cover, moorland, pasture with weeds, and pasture with long grass. 2. THINNING GRASS. As delivered, Silflor’s grass is too dense for the scrubby growth along the right-of-way. Pull it apart until the grass begins to look more realistic. Sources Silflor Products are available from the following mail order companies: Blue Ribbon Models 3. GRASS AND SOIL. Once the mat has been teased out, it’s glued down to a layer of soil using white glue. Some of the soil will show through between the clumps of grass. 4. GRASS APPLICATION. Set the mat on the wet glue and press it down with tweezers to prevent matting. Adjust the clump positions as needed with tweezers. Trim off any excess grass after the glue has dried overnight. 5. ADD DIRT. Use fine sifted dirt, worked into the grass mat with an old toothbrush, to hide the substrate fibers. Then flood the area with wet water and diluted white glue. sparse, but clumps spread farther apart until they detach completely. As the clumps pull apart, some of the grasses fall over, but enough vertical blades remain to represent late season grass. Being nylon, the blades of grass are shiny so they reflect light in a distressingly unrealistic manner. Fortunately, this sheen is easily remedied with a fine spray of matte medium. I use an airbrush to keep from gluing everything together in a big mess. I can apply this dulling spray before or after planting. Planting procedures The photos show how easy it is to duplicate the coarse grasses and undergrowth common along the railway right-of-way with the Silflor grass mats. It takes a little time, and the materials are somewhat more expensive than dyed sawdust. Begin by stretching and teasing the mat as far as it will go. Then cut it to fit the space. The spaces in the mat require application over a painted surface or one that has a soil texture so an appropriate color shows through. See photo 3. Full-strength white glue is the primary adhesive for this grass mat. Spread the glue liberally in depressions and anywhere you plant the grass. The white glue soaks in and dries transparent, making a permanent bond that holds the grass fibers upright. Use tweezers to press the grass mat into the glue as shown in photo 4. Avoid the temptation to press with your fingers as that results in a matted jumble. The tweezers also comes in handy to make minor adjustments. Don’t worry if the edges of the mat overlap the glue area as they can be easily trimmed once the glue has dried overnight. To hide the substrate fibers, pour the finest dirt you can get over the area. Use a retired toothbrush and your fingers to work the dirt into the grass and pull the P. O.

Flood the area with water wetted with a few drops of dish soap, followed by diluted white glue to secure the soil. The next morning, or when the first glue dries, add some fine dark green ground foam and a few bits of chunkier light green foam and glue it down to represent some of the other plants mixed into the grass. Patience rewarded These steps take a few evenings to accomplish, although it goes fairly quickly when I work on several areas at a time. It’s a small price to pay for the chance to go back to those youthful summer afternoons of lying in the grass listening for the first sounds of a train. 1 René Gourley, an S and HO fine scale modeler, recently moved from Canada to England, where he’s a consultant for a computer database company. A tale of three creeks These waterways illustrate both variety and consistency By Jack Burgess Photos by the author W e’ve all heard that variety is the spice of life. It’s easy to follow this advice when adding scenery to our layouts. But if we add a little of this and a little of that, we soon have a mishmash of scenes that don’t relate to each other in a realistic way. On the other hand, distinct scenes are essential to helping portray distance and variety. The solution is to take clues from nature, so slightly different scenes can be developed which will be realistic and also faithful to the prototype. As my prototype, the Yosemite Valley RR, left Merced in California’s San Joaquin Valley and headed for Yosemite National Park, it quickly crossed three creeks: Bear Creek at milepost 1.35, Black Rascal at 1.90, and Fahrens less than a mile later at 2.70. Regardless of proximity, these crossings are all unique. Bear Creek has relatively uniform banks covered with wild bamboo. Both Black Rascal and Fahrens flow along nonnative eucalyptus groves with occasional sycamores or cottonwoods along their banks. Initial modeling All three creek crossings have standard YVRR concrete abutments, so I made a mold and cast the six abutments from Hydrocal plaster. I scratchbuilt the bridges from prestained stripwood and n.b.w. (nut-bolt-washer) castings. Next I installed the bridges and roughed in the scenery with plaster. I used real dirt to form the banks. The water for Bear and Black Rascal Creeks is casting resin that I poured in layers 1⁄8" to 1⁄4" deep. Since Bear Creek is relatively deep (a scale 10 to 12 feet), I added color directly to the casting resin, using brown and green tints for the first layers and green and blue for the middle layers. The final layers I poured clear. These darker colors emphasize the deep, slow water. In contrast, just the first layers of casting resin for Black Rascal Creek were lightly colored with green and blue to result in a clear, cool creek. Once the casting resin had cured, I dappled the surface of the creeks with a coat of acrylic gloss medium. Bear Creek I duplicated the dense wild bamboo covering the banks of the real Bear Creek using Woodland Scenics field grass (fig. 1). I applied it by cutting small clumps and gluing it in place with white glue. This was tedious but produced the look I was after. While there is a tendency for the material to lean over, just keep pushing it up. As the glue dries, it will finally hold position. Using sticky white craft glue rather than regular white glue also helps. Once the bamboo was in place and the glue had dried, I used a moustache scissors to trim the material to a relatively even length. Since the banks of Bear Creek were covered with bamboo, little further detailing was needed. Black Rascal Creek In contrast to Bear Creek, Black Rascal (fig. 2) is more typical of the meandering creeks draining the foothills in the Merced area. Moisture in the adjacent ground allows the grass to remain green during the hot summer months. To duplicate these conditions, I airbrushed Noch electrostatic grass a light green. The willows which encroach into Engine no. 28 crosses Fahrens Creek on Jack Burgess’ HO Yosemite Valley RR. It’s one of the three distinct creeks he models. Fig. 1 BEAR CREEK. The deep, slow water is perfect for fishing, so Jack added a raft and a youngster whiling away an August afternoon. the creek are a combination of Woodland Scenics field grass and flower pieces from dried artichoke heads dyed light green. (Dried artichoke flowers can be found in craft stores.) Since the area next to the bridge seemed an appropriate watering hole, I mixed diluted white glue with fine-grained clay soil and spread it on the banks. I gave the muddy area a light coat of acrylic gloss medium to make it look wet. Fahrens Creek Unlike Bear and Black Rascal Creeks, Fahrens (fig. 3) is modeled as a dry creek bed, typical of the Merced area in mid-summer. I used Woodland Scenics field grass to model the bullrushes along the creek banks, hot-gluing it in place. Cattails were made with short pieces of fishing monofilament which had been dipped in white glue and allowed to dry to form the heads. I then painted the heads brown. I used fine beach sand to form the creek bottom and bonded it in place with diluted white glue. The sand was added after the field grass was in place, covering the hot glue. Portions of the real Fahrens Creek banks are covered with wild blackberry vines. To model this, I started with small poly fiber balls covered with ground foam, bonded the foam with hair spray, and glued them in place with white glue. A light sprinkling of red foam replicated ripening blackberries. Modeling scenery accurately requires no more than observing nature and, sometimes, developing techniques to reproduce what you observe. Detailing scenery can be a relaxing diversion from working on the rest of the layout. 1 Jack Burgess, who models the Yosemite Valley RR circa August 1939, contributes frequently to MODEL RAILROADER. Fig. 2 BLACK RASCAL CREEK. To complete the meandering creek scene Jack added a steer and muddy hoof prints. Fig. 3 FAHRENS CREEK. Detailing on the dry creek bed included adding cattails and bullrushes. Cajon Creek step-by-step How to model this meandering mountain stream By Ted York Photos by the author I visit Cajon Pass at least twice a year to shoot photographs and collect information for my HO Atchison, Topeka & Santa Fe. In January 2000 I was exploring the pass with Al Bowen, a good friend who is well versed in the history and geography of the area. My question for him that day was, “Where does the water come from?” Despite the dry desert look of the pass some water always flowed down Cajon Creek. In the many times I’d been there, I had never looked into the creek’s sources. Al promptly drove up a narrow road to the north of the tracks; we walked up a short trail where we found a small, clear lake nestled in the center of the San Andreas fault line. Water seeping up from cracks in the ground formed the lake, providing a source of water flowing through the pass year-round. I was amazed to be standing in a dry landscape looking at more water than I had imagined. But modeling this water would be a little different from what I had seen on most layouts because Cajon Creek is very shallow and clear, reflecting the Preparation F irst I prepared the streambed, using cardboard strips to form my scenery base then attaching cheesecloth with hot glue. Next I painted on two coats of plaster of paris mixed to the consistency of latex paint. To form the final scenery I came in with a coat of casting plaster about the consistency of cake batter. I formed the smooth areas of the riverbed by spreading the plaster with a spatula, then smoothed it as it set up by simply rubbing the plaster in a circular motion with my hand. I modeled the concrete under the bridge (the Santa Fe called them concrete blankets) with sheet styrene scribed to represent expansion joints, then installed it with casting plaster. On many areas along creeks, the bank has eroded leaving the top layers of soil hanging. Modeling this was quite simple with a sponge. I put some plaster on an area then used a damp sponge to push it toward the bank. As I did, excess plaster moved up and over the sponge. I pushed down upward bulges with my hand, smoothing it out like I did the riverbed. Dabbing at the plaster with the sponge as it sets up gives the plaster a soil-like texture. After the plasterwork was done I gave it a quick coat of a light tan latex paint. Then came the fun. I filled paper cups with dirt sifted to various grades and began tossing it over the riverbed. Since my stream was only a small portion of the entire bed and very shallow, I used dirt to form the channel that would contain the water. I added various shades of ground foam on top of the surrounding banks. Even though I’m modeling the desert Before finishing the creek Ted weathered the bridge and abutments so he wouldn’t get the weathering materials on the finished stream. A young railfan watches from below as a GP7 helper, lashed to the rear of a Santa Fe freight, crosses Cajon Creek, a year-round source of water. color of the streambed itself, varied by shadows from the surrounding rocks, vegetation, and clouds passing overhead. The following photos and captions take you step-by-step through how I modeled my steam. 1 Ted York’s previous byline in MR was a story on detailing Union Pacific FA-1s. there’s a lot of plant life, much of it very green in spring. Next I soaked the material with isopropyl (rubbing) alcohol so the glue would penetrate. I used a coat of diluted Elmer’s white glue to fasten the ground cover. Before working anymore on the stream I weathered the bridge and abutments. My weathering materials are on the messy side and I didn’t want to get them on the finished “water.” I applied a very dilute wash of black shoe dye and isopropyl alcohol on the abutments. I used chalks to streak on the rust and dirt colors that wash down from the bridge. Finally, I painted a thin wash on the bridge, using a very dilute mix of the tan latex paint I used on the plaster. Ted used a sponge to push the plaster into shape, forming the eroded banks along the riverbed. After the plaster set, Ted painted it with light tan household latex paint. Painting C orrectly coloring the water-covered portion of the streambed is one of the most important things if you want a realistic-looking stream. I studied photographs of the stream and decided a greenish brown was needed. I used tube acrylics for the project and experimented until I found suitable colors. I painted most of the stream with a raw sienna and white mix, but for the deeper mossy bottom I used an olive green mixed from black, yellow oxide, and white. I kept a separate container of water handy to dilute the acrylics as I applied them, watering down the paint as much as I could and still have it cover the dirt. I first painted the riverbed the raw sienna mix, then added the olive color, alternating between the two so I could blend them while wet. I also painted a To give a realistic look to the water Ted painted the streambed with appropriate acrylic paint colors. Ted drybrushed white where there might be a rapid movement of water, like around rocks and down the concrete blanket. thin wash of the sienna down the concrete blanket. Next I drybrushed some streaks of olive down the concrete to give the look of moss build-up where the water flowed over it. Finally I drybrushed some white on areas that might have rapid moving water, such as down the concrete and around rocks. Don’t overdo this though, unless you want major rapids. If you care to add junk to the streambed such as brush, and old tires, now is the time. Let the paint dry before going on to the next step. Sandwiching a sponge between wax paper and a piece of Masonite stops the EnviroTex from “escaping” the layout. Notice how the epoxy has creeped into the riverbank along the water. This can be covered with ground foam. Here’s the finished epoxy prior to applying the Mod Podge. It’s too smooth to represent moving water. Ted brushes on several coats of Mod Podge to build up the ripples that are found in moving water. It took three coats, spread at random, to build up a nice textured surface. On the concrete I pulled the brush down the slope to get a look of downward movement. After that set up I applied more, this time pushing the brush downward to spread the bristles as I had done with the rest of the stream. I did it several times in the same spots to give the effect of water moving down in sheets as I have often seen on spillways. Although the Mod Podge goes on white, it dries to a nice shine. Not only does the water now give the illusion of moving down the streambed, it also gave the appearance of distorting the light as I looked into the water. Another nice feature is that if the water starts to look dull after a while, I can just grab the paintbrush and give the stream another quick coat of Mod Podge and it’ll be good as new. Pouring I used Enviro-Tex Lite two-part epoxy resin for water. The fun thing about this product is that if there’s a way for the resin to escape from your streambed it will. I was confident my streambed was leakproof except for the layout edge. Sealing this escape route was quite simple: I sandwiched a synthetic sponge between wax paper and a piece of Masonite hardboard. I ran a couple of screws through the Masonite, attaching everything to the fascia and forming a tight seal. The epoxy won’t stick to wax paper. Just be sure the dam extends far enough to each side of the stream to prevent epoxy from going around the sides. The epoxy instructions tell you to pour a maximum thickness of only 1⁄8". If you need it thicker make separate pours, allowing the epoxy to cure between each. My project took two coats. I used an old brush (old, because it’s the last time you’ll use it) to direct the epoxy. I also brushed a little on the concrete blanket; I didn’t want it to be very thick there. Once I was satisfied with the pour, I left town until morning to avoid the temptation to touch the stuff and mess it up. Be aware that Enviro-Tex tends to creep up the bank; it also cures as smooth as a sheet of glass. I was modeling moving water and needed ripples, so I bought a small bottle of Gloss-Luster Mod Podge at the local arts and crafts store. Gloss Medium will work as well. I used a paintbrush to spread the Mod Podge over the cured Enviro-Tex, pushing down on the brush and spreading the bristles to form a ripple pattern.
