Modular Electronic Interlockings
Installed quickly and at low cost
Transportation Systems
Modular Electronic Interlockings
In addition to the growing requirements placed on signalling and control systems,
today‘s interlocking projects are demanding ever shorter project execution times.
Siemens Transportation Systems meets this challenge by supplying completely
prefabricated interlocking modules with ready-fitted components, and a highly
sophisticated logistics concept.
Siemens Transportation Systems has for
many years been manufacturing and supplying interlocking systems to railways
the world over. In the course of decades,
the interlocking systems have been
enhanced and refined from generation
to generation. The lessons learned in the
planning, implementation and operation
were incorporated into each successive
generation of interlockings. Standards
were defined which customers in all
railway fields can now use world-wide.
The aim of the rail operators and Siemens
as an equipper was and is to achieve the
maximum possible reduction in project
execution times, planning outlay and
costs, and follow the trend towards ever
more high-performance interlockings
installed in increasingly short time
periods. This resulted in the development of modular interlockings. Over
150 modular electronic interlockings
have already been installed world-wide.
Siemens Transportation Systems‘ many
years of experience stand our customers
in good stead.
Benefits of the modular design
> Time savings during the licensing
procedure compared with traditional buildings because the modules are
type-tested, dispensing with the
lengthy approval procedure.
> Short construction time on site as all
the components of the building are
prefabricated.
> Optimal blending in with nature and
the environment because town
planning requirements are easily
implemented.
> Rapid availability of the building,
allowing other equippers to use the
building only a few hours after
installation of the modules.
> Freely selectable interlocking size (due
to the system‘s modular structure).
> Reduction in project execution time
because the installation of the indoor
signalling and safety equipment in the
modules is carried out at the same time
as the foundation work on site, the
construction of the outdoor signalling
equipment and the data testing in the
Siemens System Test Centre.
> Reduction in commissioning work on
site because the indoor signalling and
safety equipment is delivered to the
construction site ready-made and
factory-tested.

Detailed planning of the interlocking
On the basis of the signalling and safety
bills of quantity and requirements for
other subsystems, such as:
> telecommunications equipment,
> 50 Hz utility power supply network
(in Germany) and
> local control systems, such as the point
heating system, platform illumination,
platform PA system and platform
surveillance (CCTV),
the precise size can already be determined during the planning approval or
permission phase. The basic module
required (see table, page 7) for the
indoor signal and safety equipment and
its power supply system can be precisely
determined using a space requirement
assessment program made available by
Siemens Transportation Systems.
Delivery
of the modules
The basic modules are available in
reinforced concrete or steel.
The smallest basic module can accommodate the indoor equipment of a small
interlocking. Owing to the modularity,
there are no upward limits to the size.
The interlocking building can be either
single or multi-storey.
Once the plan of the building is available,
it is possible to check whether it can be
erected at the desired location.
Conditions imposed by towns and local
authorities are to be incorporated into
further plans (local planning regulations).

The planning documents are compiled in
accordance with the relevant railway
regulations and general, technical and
other regulations.
For secondary lines with interlockings up
to 40 connection units, smaller modules
can be used. These modules are manufactured as monolithically moulded reinforced concrete cells, with the walls
and cell floor slab moulded in one piece.
In the station modules for secondary
lines, the following signalling and power
equipment can be installed:
Signalling system
> a cabinet for area control computers,
bus transmission and axle counting
(up to 6 counting heads) and an EOM
(element operating module) cabinet
(with up to 21 locations)
> one rack for block transmission, one
EOM rack and one outgoing panel
(cable termination rack)
Power supply
> two cabinets with an uninterruptible
power supply (UPS)
> battery system of the UPS (standard

Structure of the
Modular Interlocking
Compact high-tech
Structure
Lightning protection
The outline dimensions of the individual
modules depend on the structure and
static requirements of the outer wall. For
enclosed structures the wall thickness is
generally 12 cm, plus heat insulation and
exterior rendering.
For the interlocking equipment, an
equipment room is provided to accommodate the computer cabinets, relay
racks and outgoing panels, as well as the
power supply equipment of the signalling
system.
An extension is possible, depending on
the application, with the following extension modules:
Kitchen
Control room
Cable distribution cabinet
> Stand-by power room for the install ation of a stand-by generating set
Service computer
> Battery room to house batteries for the
Computer
signalling system
> Rooms to accommodate telecommuni cations, heavy current and local
control system equipment
Diesel generator set
> Rooms to accommodate equipment for
supplying power from the contact line
in the event of a failure of the stand-by
diesel generator set extension module

Besides the equipment rooms, the basic
modules can be supplemented with other
functional rooms created from extension
modules:

Basic module G6.1 6.69 m x 6.06 m
> sanitary rooms,
> day rooms and
Basic module G6.2 8.49 m x 6.06 m
> storage rooms.
If the extension modules are to be
used as working and business premises
(signalman‘s workroom), the extension
modules are fitted with windows and the
necessary water supply and sewerage
system, as well as improved heat insulation.
Once the roof has been completed, the
signal box (interlocking building) is fitted
with a lightning protection system.

Design of the roofs and outside walls
The basic module of the interlocking
building is supplied to Siemens Transportation Systems by the manufacturer.
The module is then fitted with the indoor
signalling and safety equipment at the
Siemens plant. Before delivery to the
project site, the finished system is tested
and inspected. Next the basic module is
assembled with all the extension modules
at the installation site to create the
finished interlocking building.
Modules which are not fitted beforehand
are delivered by the manufacturer directly
to the construction site on the day when
they are to be set up.
The modular concept allows the building
to be adapted to local surroundings.
Various types of roofs and facing can be
selected.
Gabled and hipped roofs have an inclination of 30 degrees (other roof inclinations are possible on request).
For the roofing, concrete tiles in the
available colours are used, or on request
special roofing materials.
Lean-to and waggon roofs are available
as special options.
The wooden lagging of the gables can be
provided in various shades.
Other forms of gable are also possible.
Facing with a synthetic resin rendering
can be provided in different colours,
likewise the doors or gratings.
The lifespan of modular interlockings is
the same as that of conventional buildings.

Construction process at the trackside
The construction site freed of overhead
and underground cables and plant
growth is levelled.
Then the foundation work begins.
Next, the cable inlets required for the
interlocking building are prepared. The
construction activities at the trackside are
limited to civil engineering work for the
foundations and cable pits, and completion of the module complex with the roof
and facing work.
Because the equipping of the basic
module and civil engineering work on
site start at the same time, the civil
engineering work can be carried out at a
relatively late stage in the execution of
the project. The interlocking building is
transported to the installation site using
low-bed lorries and then lowered onto
the continuous and column footings.

guarantees efficiency, a long service life
and largely trouble-free operation of the
electronic interlockings. The reliability of
all the components is ensured by
Siemens on the basis of extensive testing
during manufacturing, which is also
carried out under extreme conditions.
Prior to commissioning, Siemens checks
all the system and project-specific data in
its own System Test Centre.
Here all the outdoor elements are simulated as part of a process simulation and
a complete data test is carried out.
Siemens achieves the extremely short
installation times by supplying prefabricated modules with ready-fitted components, and a highly sophisticated logistics
concept.
Exterior options
Process steps in accordance with
DIN EN ISO 9001
Throughout the process Siemens conforms to DIN EN ISO 9001 – from the
start of development to commissioning
of the interlocking. Siemens can
therefore guarantee first-class quality,
an above-average service life and a high
maintainability for its products.
