Reinforced Earth® retaining walls are used in many countries along railway, metro and light rail transit lines. The technology is the same as for roadway applications, except for a few specific details.
The design of the retaining structures is adapted to comply with the stringent requirements related to heavy loads and safety, especially for highspeed railways. Reinforced Earth® structures absorb the vibrations induced by passing trains, inherently well.
Building a Reinforced Earth® retaining wall along a railway does not require any scaffolding, or any structural footing in front of the cladding. As a result, the wall can be built without interruption of traffic.
TechSpan® arches are frequently used as well for the construction of railroad tunnels beneath earthen embankments. They can be constructed over existing railway tracks without closing the line.
