Ballast

Track ballast is the material which forms the trackbed upon which railroad ties are laid It is packed between, below, and around the ties (also known as “sleeper) 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 tracFor history's sake, ballast has its earliest beginnings as simple limestone blocks, which actually sometimes pulled double duty as both the support base and railroad track structure In the 1840s true Railroad Ballast (Rock): Specifications, Sizes, Background
