Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).
Some light density railroad lines would appear jet black as nothing but burnt coal cinders were used to ballast the route. In any event, track ballast must regularly be cleaned or added as when dirt and grime builds up within the rock it reduces its ability to properly drain water.

As ballast density tests can be more difficult in ballast than field mechanical strength or stiffness tests, several mechanical tests have shown promise for field ballast assessment including plate load tests used on the Channel Tunnel Rail Link (O'Riordan and Phear 2001).
