Серия MPI MPXpress
MPXpress is a series of diesel-electric passenger train locomotives designed for commuter rail service. The locomotives are built by MotivePower, a subsidiary of Wabtec. To date, MPI has offered five main variants: MP36PH-3S, MP36PH-3C, MP40PH-3C, MP32PH-Q, and MP54AC. However, due to federal emissions standards, the MP54AC is the only locomotive currently for sale in the United States, as it is the only MPXpress locomotive that meets Tier IV standards.
