Together with its American partner EMD (Electro Motive Division), Siemens supplied the first production diesel-electric freight locomotives with three-phase AC propulsion technology. The initial order placed by the U.S. railroad company Burlington Northern (BN) in 1993 for a total of 350 locomotives marked the largest single order in U.S. railroad history. Successful operation has since led to follow-up orders, bringing today’s total number of locomotives equipped with Siemens three-phase technology to 786.
