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.
