Why do they put gravel on railway tracks?

The crushed stones are what is known as ballast. Their purpose is to hold the wooden cross ties in place, which in turn hold the rails in place. The answer is to start with the bare ground, and then build up a foundation to raise the track high enough so it won’t get flooded.

Why Railway tracks do not rust?

The biggest reason is that the steel used in rail is composed of a higher quality steel alloy. Actually different types of metal are also mixed in the steel used in rail tracks. The top and upper side face of a rail doesn’t usually corrode because friction and wear keep it polished and free of rust.

How far should you be from a railroad?
