A diesel-electric locomotive is equipped with a diesel engine that spins a generator (DC) or alternator (AC) to create electricity. This electricity then powers the heavy electric motors that move the train forward. A diesel-electric locomotive has no mechanical connection between the prime mover and the axles.
