Track ballast - Wikipedia

The appropriate thickness of a layer of track ballast depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors. Track ballast should never be laid down less than 150 mm (6 inches) thick, and high-speed railway lines may require ballast up to 0.5 metres (20 inches) thick. An insufficient depth of ballast causes overloading of the underlying soil, and in unfavourable conditions, overloading the soil causes the track to sink, usually unevenly. Ballast less than 300 mm (1

Why There Is No Ballast on High Speed Rail Track?

Ballast refers to the gravel or crushed rock paved on the road or railway subgrade, it is mainly used in railway subgrade. Ballast is one of the main components in the railway transportation system, used to support the railway sleeper and rail track. Before laying tracks, a layer of ballast is needed to pave on the railway subgrade. The use of ballast is very available for water drainage and the track position adjustment. Rail ballast
