Track (rail transport) - Wikipedia

Railway tracks are generally laid on a bed of stone track ballast or track bed which in turn is supported by prepared earthworks known as the track formation. The formation comprises the subgrade and a layer of sand or stone dust (often sandwiched in impervious plastic) known as the blanket which restricts the upward migration of wet clay or silt. There may also be layers of waterproof fabric to prevent water penetrating to the subgrade.
