A four-wheeled configuration where all the wheel is driving wheels used all the locomotive’s weight for traction, but is inherently unstable at speed. The type was therefore mainly used for switchers. They were used in situations where tighter radius curves existed or the shorter length was an advantage. Thus they were commonly employed in dockyard work, industrial tramways, or as shop switchers. The wheel arrangement is also used on specialist type such as fireless locomotives, crane tanks, tram engines, and geared steam locomotives.
