Mallet locomotive

The Mallet locomotive is a type of articulated steam railway locomotive, invented by the Swiss engineer Anatole Mallet (1837–1919). The articulation was achieved by supporting the front of the locomotive on an extended Bissel truck. The compound steam system fed steam at boiler pressure to high-pressure cylinders driving the main set of wheels. The exhaust steam from these cylinders was fed into a low-pressure receiver and was then sent to low-pressure cylinders that powered the driving wheels on the swiveling bogie.
