Tramway (industrial)

Tramways are lightly laid railways, sometimes with the wagons or carriages moved without locomotives. Because individual tramway vehicles are not intended to carry the weight of typical standard-gauge railway equipment, the tramways over which they operate may be built from less substantial materials. Tramways can take many forms; sometimes just tracks temporarily placed on the ground to transport materials around a factory, mine or quarry. Many, if not most, use narrow-gauge railway technology.
