Product is for model Railroad Ballasting on and around the railroad tracks or around the model railroad layout or other scale models.
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 track bed upon which railroad ties (sleepers) 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 by. It is typically made of crushed stone, although rock has sometimes consisted of other, less suitable materials, for example burnt clay. The term “ballast” comes from a nautical term for the stones used to stabilize a ship. The appropriate thickness of a layer of track rock depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors.Track rock should never be laid down less than 150 mm (5.9 inches) thick; and high-speed railway lines may require rock up to 1⁄2 metre (19.7 inches) thick. An insufficient depth of rock causes overloading of the underlying soil, and in unfavourable conditions overloading the soil causes the track to sink, usually unevenly. Rock less than 300 mm (11.8 inches) thick can lead to vibrations that damage nearby structures. However, increasing the depth beyond 300 mm (11.8 inches) adds no extra benefit in reducing vibration.
