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.

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.

Ballast, like most things on the railroad, requires regular maintenance. Over time ballast begins settle and lose its shape. In addition, rock fragments from worn ballast, spilled commodities, locomotive sand (used for traction), and soil can prevent proper drainage. Railroads and contractors often use self-propelled equipment to maintain ballast.
