The design of bogie bolster wagons had developed from earlier timber wagons, which were short four-wheeled wagons, each carrying a single swivelling bolster. A pair of such wagons could carry a large tree trunk to a sawmill, but they required either the tree to take the full tension of the train, or a suitable number of

is a
British railway term for a wagon designed to carry long thin cargoes such as timber or rails and other steel sections. The sides and ends are minimal and there is no roof. The load is carried longitudinally and borne by three or more bolsters (half baulks of timber) fixed transversely. The load

Bolsters could be fixed in place, or be removable. Some had as many as five bolsters. Some designs had multiple sockets and a pair of bolsters could be moved between them. The bolsters could even be allowed to swivel around a central locating pin, and curved steel rubbing strips on the wagon deck.

posts etc. are stiff enough that they only need to be supported at intervals, not continuously across a flat planked bed. The space between baulks allows room for tie-down chains or lifting straps, making the bolster design easier to work with than a completely flat bed.

Bogies are four-wheeled, articulated carriages beneath the main load bed. They allow a long wagon to carry long loads, but still have individually short wheelbases, and so go round

Bolster wagons are relatively lightweight. Heavier well wagons, used for machinery loads, had deeper and stronger side girders. They had a cranked side profile, so that the
