These locomotives are fueled by burning combustible material, usually coal, wood or oil, to produce steam in a boiler, which drives the steam engine. steam locomotive 蒸汽机车 The history of trains Fixed tractor 牵引机 + track 铁轨 steam locomotive 蒸汽机车 1817 1879 electric locomotive 电力机车 electric locomotive 电力机车 An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or fuel cell.
