The EMD MP15T was a model of diesel-electric switcher locomotives built by General Motors Electro-Motive Division between October 1984 and November 1987. Instead of a mechanically-aspirated 12-cylinder EMD 645 engine, it used a turbocharged 8-cylinder version of the 645 engine. The external appearance of the locomotive remains similar to other MP15 models.

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

In 2010 Progress Rail, a fully owned subsidiary of Caterpillar, purchased MP15T 1220 from CSX making CSX's total count 40.
