Drive System of a Railway Locomotive All modern Electric & Diesel locomotives are hauled by traction motors. An electric locomotive is powered by electricity from overhead high-tension (voltage) electric lines through pantographs and transformers. In contrast, diesel locomotive has Traction Alternator connected to the engine & electricity generated by the alternator is used to power
