    Track ballast - Wikipedia

    OverviewConstructionMaintenanceQuantitiesTrack ballast forms the trackbed upon which railroad ties are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. This also serves to hold the track in place as the trains roll over it. Ballast typically consists of crushed stone, although other, less suitable materials have sometimes been used such as burnt clay. The term "balla

    Railroad Ballast and Other Track Materials

    Railroad ballast serves as a bed for railroad tracks and provides track stability, drainage, and support of significant loads carried by railcars. In addition, it deters the growth of vegetation and allows for track maintenance to be performed more easily.

    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).
