Third Rail Systems

In joint venture with Constellium Group, Railtech Alu Singen develops and supplies complete solutions of composite conductor rail systems (aluminum/stainless steel conductor rail) for all metro applications.

Our conductor rail is made using coextrusion technology which delivers the highest levels of reliability and safety, with no delamination and no need to control the thickness of stainless steel. Solutions are designed with consideration of rolling stock, track works, power supply and civil works interfaces.

Our solution can be adapted for use on all track types, and our team has extensive experience with all aspects of transit power rail systems, and supports with product engineering and design, proof of concept testing, system design, and installation supervision and training.

Technical Features

Coextruded rail delivers the highest levels of reliability and safety
Anchoring solutions are selected from of a wide range of standard Pandrol products
A full analysis of layout including turnouts, crossovers and diamond crossovers is undertaken to ensure train power continuity
Protection board brackets are used to support the protection board at a distance above the steel contact rail
All of our products have been developed for railway environment considering safety and reliability, including fire and smoke emission, and lifetime value
A full range of dedicated tools are available to support installation

Advantages

We have extensive track expertise to ensure full the railway system is fully considered
Full technical service and support can be provided by our expert team throughout the installation and commissioning phases
Designed for easy installation and low maintenance
A flexible design can deliver third rail systems for top-running, lateral and under-running systems
Designed with outstanding electrical properties, our insulating covers provide protection for employees working near the track

Solutions

Under running solution

The current collector shoe touches the third rail system from underneath. The third rail system is fully covered by insulating material.
Top running solution

The current collector shoe touches the third rail system from the top. The third rail system is generally covered by insulating material, leaving an access for train's current collector shoes.
Lateral running solution

The current collector shoe touches the third rail system from the side.

Components

Conductor Rail

Coextruded rail combining aluminum & stainless steel
Splice Joints

A pair of aluminum extruded splices (plates) fixed to the web of the conductor rail using a bolting connection
Ramps

Used to evenly engage and disengage the train current collector shoe during transitions
Insulators & Brackets

Manufactured in a glass reinforced polyester, designed to insulate the third rail system and withstand mechanical stresses
Mid Point Anchors

Designed to control the expansions and contractions of the third rail system, caused by temperature variation
Expansion Joints

Designed to accommodate thermal expansion and contraction of the third rail system, due to ambient temperature variation and heat rise
Cable Terminals

Fixed to the web of the conductor rail by means a bolting connection
Insulated Joints

Designed to split (insulate) two electrical sections of third rail system
Covers

Fastened to the conductor rail to minimise the risk of electrical shock due to accidental contact with the conductor rail and to provide protection against debris
