Bogie

A bogie comprises two or more wheelsets, in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached or be quickly detachable. It may include suspension components within it, or be solid and, in turn, be suspended. It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung, or held in place by other means.
