The running gear of a modern railway vehicle comprises, in most instances, a bogie frame with two wheelsets. However there are also wagons with single axles (fixed or movable) and even individual wheels.

The small rail wheels fitted to road–rail vehicles allow them to be stowed away when the vehicle is in road-going mode. Wheels used for road–rail vehicles are normally smaller than those found on other types of rolling stock, such as locomotives or carriages, because the wheel has to be stowed clear of the ground when the vehicle is in road-going mode.
