A grey 00-gauge model of a Bolster Bogie Wagon D1, Hornby Dublo 4610, with black bogies, in its original box packing. The wagon has is marked "30T", "15-8" and numbered "M 720550", with all text in white against black rectangles. The upright load-retention posts are black.

The model is embedded in its packing card, and sitting on top of its box (which is red with thin white lines).

Although the style of the wagon sides is supposed to be representative of a bogie bolster wagon (and the wagon has the words "BOGIE BOLSTER" proudly diplayed on its side, in white capital letters), the model itself only has four axles and two bogies.

Bogie bolster wagons

Bogie Bolster wagons are designed for heavy loads, and have a lower side-profile similar to a drop wagon.

The idea of a bolster wagon is that, while a bogie acts as a frame for multiple wheel axles, a bolster is an additional subframe that carries multiple bogies. A "bolster bogie" wagon might typically have four bogies, but grouped in pairs on two swivelling bolsters instead of being individually fixed to the wagon. The use of bolsters means that the bogie mounting points aren't forced to lie in a straight line along the centre of the wagon, and are free to swing away from the centre-line as the bolsters rotate to follow the line of the track. A bolster wagon therefore combines the ability to follow curved tracks easily that one would associate with a simple four-wheeled wagon, or with a simple two-bogey wagon, with the ability to spread a long heavy load over a large number of wheels.
