Why do train tracks sit on rocks?

Railroad ballast is a crucial component of the rail transportation system. It is a crushed stone or gravel material that is used to support and level the tracks in a railroad track bed. The primary purpose of ballast is to provide stability to the tracks, allowing trains to run smoothly and safely.

It is used to bear the compression load of the railroad ties, rails, and rolling stock; to facilitate drainage; and keep down vegetation that can compromise the integrity of the combined track structure. Ballast also physically holds the track in place as the trains roll over it.

First you've got the rails – these are the long metal strips on which the train wheels run. Because they're metal, they can be affected by changes in temperature, which can cause them to expand and contract. Sleepers are the horizontal supports which lie underneath the rails, helping hold them in place.

A lot of trains are powered by electricity. The third rail or electrical line running in parallel with the tracks provides power. The voltage of the lines transforms into electrical current through transformers, which power the wheels' motors.
