A specific type of stone must be used for railroad ballast. If the stones are too smooth, such as river rock, the pebbles would roll over or slide against one another when a train passes. In order to provide support to the tracks, stones with angular edges must be used. The angular nature of rail ballast allows the stone to lock in place.

1- Crushed Stone: This is the most common material used for railway ballast. Crushed stone is selected because of its strength and angularity, which allows it to lock together and provide a stable base for the tracks. Granite and limestone are frequently used types of crushed stone due to their durability and resistance to weathering.
The crushed stones, also called ballast, alongside rail tracks are there to hold the tracks in place as the tracks move with the passage of trains or due to heat expansion and contraction. For rail lines that use certain types of electrical systems in the rails, ballast also provides an insulation between the rails. ...
