A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a self-propelled steam engine on wheels.

In most locomotives the steam is admitted alternately to each end of its cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally.

The Deutsche Reichsbahn Class 01.10 was a series of express steam locomotives. Developed at the end of the 1930s it was part of the standard locomotive programme (Einheitsdampflokomotiven). Modernized in the 1950s, the class lasted almost until the end of steam operation at the West German Deutsche Bundesbahn (DB).
