[[File:RunningGear.jpg|thumb|Running gear of wooden wagon found in Ferron Utah, build around 1890. ]] The term "running gear" dates back to horse, or ox, driven wagons. The "gear" portion of the term is a synonym to "equipment", "outfit", "tackle" or "rig"; as used in the sentence: "Grab your gear" or "Gear up". It is not to be confused with mechanical "gears"; such as the found in an automotive transmission. Hence the term "running gear" can denote the wheels and subframe of a wagon pulled by a horse or ox; generally, the four wheels, axles, and frame holding these components together. Hence, the running gear is a component of a [[rolling chassis]] (minus an engine and transmission). |

In railway terminology the term running gear refers to those components of a railway vehicle that run passively on the rails, unlike those of the driving gear. Traditionally these are the wheels, axles, axle boxes, springs and vehicle frame of a railway locomotive or wagon.[1] 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. Since in modern times, locomotives no longer require separate driving and carrying axles (see wheel arrangement), as was formerly common with steam locomotives, but usually have bogies where all axles are driven, the term running gear is (inaccurately) superseding the term 'driving gear' in some parts of the world.
