Articulated locomotive

Three methods of articulating a steam locomotive

Articulated locomotive usually means a steam locomotive with one or more engine units which can move independent of the main frame. This is done to allow a longer locomotive to negotiate tighter curves. Articulated locomotives are generally used either on lines with extreme curvature—logging, industrial, or mountain railways, for example—or to allow very large locomotives to run on railways with regular track curvature. Articulation is also applied to some electric locomotives, such as the Italian FS Class E656.
