Railroad Ballast (Rock): Specifications, Sizes, Background

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).
