Track ballast - Wikipedia
Good quality track ballast is made of crushed stone. The sharp edges help the particles interlock with each other. Track ballast (close up) between railway sleepers and under railway track. Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed for use in heavy traffic, or with continuous welded rail or concrete ties.
