Micromax Rail Pad

Unique microcellular rail pad ensured to have excellent all-round qualities with outstanding performance in both impact attenuation and overload conditions. Available in thicknesses of 5.5, 7.5 & 10.5mm.

When used as a rail pad material Micromax reduces dynamic forces from the track into sleeper systems. In this way it is possible to give older sleeper designs modern levels of impact protection. Micromax pads are also available for new build track.
