Under the [[Whyte notation]] for the classification of [[steam locomotive]]s, '''2-2-2''' represents the [[wheel arrangement]] of two [[leading wheel]]s on one axle, two powered [[driving wheel]]s on one axle, and two [[trailing wheel]]s on one axle. The wheel arrangement both provided more stability and enabled a larger [[Firebox (steam engine)|firebox]] than the earlier [[0-2-2]] and [[2-2-0]] types. This wheel arrangement is sometimes described as a '''[[single (locomotive)|Single]]''', although this name could be used to describe any kind of locomotive with a single pair of driving wheels.
