Wheelset (rail transport)

Bogie from an MP 89 Paris Métro rolling stock showing the two special wheelsets

A wheelset is the wheel - axle assembly of a railroad car. The frame assembly beneath each end of a car, railcar or locomotive that holds the wheelsets is called the bogie (or truck in North America). Most North American freight cars have two bogies with two or three wheelsets, depending on the type of car; short freight cars generally have no bogies but instead have two wheelsets.
