A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine. These locomotives are fuelled by burning combustible material – usually coal, wood, or oil — to produce steam in a boiler. In most engines, the steam moves reciprocating pistons which 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 wagons (tenders) pulled behind. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally.
