Reinforced Earth® retaining walls are used in many countries to support high speed and heavy railways, as well as metro and light transit lines.

Studies demonstrate that Reinforced Earth® structures absorb the intense vibrations created by passing trains and the sudden massive stresses associated with massive breaking loads.  In addition, Reinforced Earth® structures are not adversely effected by stray currents associated with electrified railway lines.

TechSpan® precast tunnels are also frequently used in railway applications beneath earthen embankments and can be constructed over existing tracks without closing operating railway lines.
