MotivePower, Inc. (MPI) is an American manufacturer of diesel-electric locomotives. The company is a wholly owned subsidiary of the Wabtec Corporation, and traces its history back to the MK Rail division of Morrison-Knudsen.
Morrison-Knudsen established a separate rail division, MK Rail, in 1972. Morrison-Knudsen spun-off the division in 1993; it became a publicly traded company in 1994. After Morrison-Knudsen's bankruptcy in 1996, MK Rail renamed itself MotivePower Industries, doing business as Boise Locomotive. The company merged with Westinghouse Air Brake Company in 1999 to form the Wabtec Corporation. Wabtec renamed the Boise Locomotive division to MotivePower in 2000. MotivePower continues as a wholly owned subsidiary of Wabtec.
