Collector Pans
A Versatile System
Contech Collector Pans
Economical, Efficient Containment
of Liquid Pollutants
Contech Collector Pans are a modular
system of steel pans and drains easily
installed on existing or new tracks to
catch wastes such as spilled or leaking
fuel, oils and greases and other
pollutants.
Their effectiveness has been proven
in hundreds of installations for
both railroads an industry. Typical
applications are along fueling stations,
ready tracks, tank car loading and
unloading areas, washing facilities
- anywhere that oils, chemicals and
other pollutants cna drip from standing
cars and find their way into sewers and
streams.
Pans are installed to cover the area
completely between and immediately
outside the rails. Cross drains are
installed at right tangles to the track
between the ties to carry wastes and
rainwater into under drains and on to
treatment and disposal facilities.
Three Adaptable Designs
Type 1 Collector Pans are designed
for and are generally used at fueling
areas. They also have been used at
washing facilities and industrial tracks
with heavy waste loads.
Type 2 and Type 2-Modified Pans are
simplified versions of the Type 1 Pan.
They are designed for ready tracks or
other areas with less waste. They have
proven excellent for fueling areas with
existing or new concrete platforms.
Because they use fewer parts, both
Type 2 and Type 2-Modified Pans
are less expensive than Type 1 Pans.
However, Type 1 Pans provide a tighter
barrier against spills and are best
suited for critical control areas. Type 2
Contech Type 2 Collector Pans on ready tracks. The grating over the cross drain allows personnel
to easily walk from side to side.
Pans offer more adaptability where
curves, platforms and turnouts are
involved.
Long Service Life, No
Obsolescence
The strong and flexible steel
construction of Contech Collector Pans
helps avoid the cracking and resulting
leaks that are possible with non-steel
pans. And should an accident damage
a Contech Collector Pan, its modular
construction means that only the
damaged section need be replaced at
minimum cost.
Contech Collector Pans are also
completely reusable. Yard layouts and
the locations of fueling facilities and
ready tracks change. Unlike concrete
structures, Contech Collector Pans can
be easily relocated at small cost.
In addition, Contech Collector
Pans are easily removed for track
maintenance simply by removing a few
bolts. When reinstalled later, they still
perform like new.
Components are also available in
galvanized or stainless steel. Type 1
and 2 are galvanized in accordance
with ASTM A123, except minimum
coating weight shall be 2 Oz/Sq. Ft.,
total both sides. Type 2-Modified when
specified galvanized is manufactured
from pregalvanized steel conforming
to ASTM A446 with a minimum 2 Oz/
Sq. Ft. coating, total both sides.
Easy Field Installation with
Minimal Downtime
Contech Collector Pans are engineered
to be simple in design, rugged for
handling ease, and easy to install. No
special installation skills are needed.
A competent foreman, a welder,
and four or five unskilled laborers
can easily install a Type 1 or Type 2
Collector Pan system. A welder is not
needed for Type 2-Modified Pans if rail
joints are welded.
Installation involves only a minimal
amount of track down-time. Contrast
this with a comparable installation of
concrete aprons. The concrete requires
extra weeks of expensive, wasted time.
Contech Collector Pans
Modular Construction is Key to
Versatility
While certain dimensions of Contech
Collector Pans are standard, a wide
range of module combinations can be
made to meet specific requirements.
For example:
• Contech Pans can be used on
tracks with a descending grade
as easily as on a level track and
often they are more economical.
• On installations around curves,
Type 2 Pans can be furnished
pre-formed to fit most curves
and simple field modifications
will meet practically and field
condition.
• If desired, pans can be installed
between the concrete platforms
on each fueling track.
• Underdrains can be included as
part of your Contech Collector
Pans system, and our plastic
pipe has proven effective for
this purpose. Joints are oil-tight,
flow characteristics are excellent.
Manholes and catch basins are
also used on many installations.
• Contech Collector Pans are
easily fitted around rail joints
by field cutting with a torch
to the approximate outline of
the joint bars and bolts. We
strongly recommend that rail
joints be welded through all pan
installations.
• Tie movements does not affect
the performance of Contech
Collector Pans. The pans are
not rigidly attached to the ties
but “float” on them. With Type
1 Pans, the aprons, attached
to the rails, hold the pans in
place. Type 2 Pans are bolted
On this installation, concrete platforms were poured with a nosing angle on the edge. A zee
flashing angle is welded to the angle, protecting against oil leaksage.
tightly to anchor angles under
the rails, holding the pans down
and securely against the rail
web. Type 2-Modified Pans are
fastened directly to the channelshaped cross drains with selfdrilling screws.
• Type 1 and Type 2 Collector
Pans are appropriate for use on
signaled track.
