Quarry tub
Railway wagon used at quarries and mines
From Wikipedia, the free encyclopedia
A quarry tub or tub is a type of railway or tramway wagon used in quarries and other industrial locations for the transport of minerals (such as coal, sand, ore, clay and stone) from a quarry or mine face to processing plants or between various parts of an industrial site.[1] This type of wagon may be small enough for one person to push, or designed for haulage by a horse, or for connection in a train hauled by a locomotive. The tubs are designed for ease of emptying, usually by a side-tipping action. This type of rail vehicle is now mainly obsolete, its function having been mostly replaced by conveyor belts.
