What it is
The MPI MP40PH-3C is a diesel-electric passenger locomotive built by MotivePower (a subsidiary of Wabtec) as part of the MPXpress line. The MP40PH-3C is one of several MPXpress models produced for commuter rail service in Canada and the United States.[1]
How it works
The MP40PH-3C uses a 16-cylinder EMD 710 G3B series diesel engine as its prime mover, capable of generating 4,000 horsepower. The locomotive also uses an EMD alternator and traction motors. Head-end power (HEP) is supplied by a separate generator, distinguishing it from earlier models that used a static inverter.[1]
