It also takes the compression load of the track, locomotives, and rolling stock. The ballast physically holds the track in place & prevents its movement.

Abstract. Railway ballasts are broken pieces of hard rock within the grain size range of 25mm-60mm, over which the railway tracks are laid. Quarries in dolerite, greywake, shale, pebbles and granitic rock formations are some of the major sources of large stones that may be selected as railway ballast based on a range of properties.
