A steam locomotive is a rail vehicle that provides the force to move itself and other vehicles by means of the expansion of steam. 80 It is fuelled by burning combustible material (usually coal, oil or – now rare – wood) to heat water in the locomotive’s boiler to the point when it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels.
