EMD MP15T Diesel-Electric Locomotive
The EMD MP15T is a 4-axle diesel switcher locomotive built by General Motors Electro-Motive Division between October 1984 and November 1987. Instead of a non-turbocharged 12-cylinder EMD 645 engine it uses a turbocharged 8-cylinder engine. The external appearance of the engine remains similar to other MP15 models.

42 of these locomotives were built for the Seaboard System Railroad, 1200-1241 (later merged into CSX where they kept their numbers) and one unit for Dow Chemical Company, number 957.

In 2010 Progress Rail Services, A Caterpillar Company, purchased MP15T 1220 from CSX making CSX's total count 40.
