The retaining structures alongside railway lines must be perfectly capable of absorbing the vibrations caused by passing trains and supporting the high stresses generated by accelerating and decelerating trains. Reinforced Earth® can be used to build the structures that support and run alongside railway tracks. In these applications, the technology used is the same as for roads. However, the design must be specifically adapted to train loads. Railway applications use the same technologies as those for roads, although the design is clearly modified to reflect specific requirements relating to overloading and factors of safety, especially for high-speed trains. The Reinforced Earth® and TechSpan® technologies are used in the construction of all types of train tracks, including light rail transit, tramways, tram-trains, regional transport, intercity services, high-speed lines and freight services, as well in the construction of a wide array of railway structures, such as:
- Trackside retaining walls
- Bridge abutments spanning railway tracks
- Retaining walls and bridge abutments supporting track beds
- Railway tunnels in embankments and cut-and-covers
- Protective embankments
Benefits
Minimal interruption to traffic
Minimal interruption to traffic
Reinforced Earth® structures require very little space and cause minimal interruption to traffic during construction. Built from the backfill side, requiring no equipment or structure set in front of the panels, our structures can be erected directly next to existing railways.Minimal deformation
Minimal deformation
Railway loads differ from highway loads in intensity, frequency, and associated vibrations. The inextensibility of steel strip soil reinforcements guarantees minimal deformation under high loads, high speed, and sudden braking decelerations.No need for deep foundations
No need for deep foundations
While traditional bridge abutments often require foundations, our Reinforced Earth® system can be built on relatively poor soil, saving you the burdensome space and scheduling requirements of excavation, or driven or drilled pile equipment.
