The stone of size larger than 5.1 cm is not preferable due to poor interlocking property. The best-recommended ballast is that which contains stones ranging in size from 1.9 cm to 5.1 cm. The size of the ballast mainly depends upon the type of sleeper used and the location of the rail track. The following sizes of
