Abstract
A railway geogrid construction is suitable for use with high speed trains to mitigate the increased impact of Rayleigh waves generated at high speed and/or over soft subgrades. The construction includes a track bed which defines a track located on a track plane, a mass of particulate material such as an aggregate forming a layer located beneath the track plane, and a geogrid located in and/or below the particulate mass in a geogrid plane substantially parallel to the track plane where the average distance between the track plane and geogrid plane, measured perpendicular to both, is greater than 0.65 metres.
