An EMD GP60 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between 1985 and 1994. The GP60 was EMD's first engine that was classified as a "third-generation" locomotive. Hidden behind the electrical cabinet doors on the rear wall of the cab, the GP60 concealed a trio of microprocessors that monitored and managed a host of engine, cooling system and control functions. The engine's on-board microprocessors replaced hundreds of wiring circuits, dozens of relays and all but one module card, making it an improvement among EMD's engines.

Power was provided by a 16-cylinder 710G3A diesel engine, which could produce 3,800 horsepower (2,800 kW). This locomotive was 59 feet 9 inches long and featured a 3,700-US-gallon (14,000 L) fuel tank. The GP60 series shared the same frame as the GP59. Cabless units of this locomotive model were also built; they were known as GP60B models, purchased exclusively by the Atchison, Topeka and Santa Fe Railway. Units built with a comfort/safety cab and a wide nose were designated GP60M and all purchased by the Santa Fe. A total of 294 GP60, 23 GP60B and 63 GP60M units were built by EMD. Due to the mainstream focus of railroads on powerful six-axle units, and strict emissions standards, the GP60 will most likely be the last new EMD "Geep".

Santa Fe followed its 40 standard-cab GP60s with an order for 63 custom GP60Ms. The GP60M featured North American Safety cabs, and was the only 60 Series B-B locomotive with this feature. The nose has a headlight that is slightly offset to the right to accommodate the front door. The first new units delivered in the road's revived "Super Fleet" Warbonnet Paint Scheme. Santa Fe GP60Ms 100–162 were delivered between May and September 1990.

23 GP60 B units were built, all for Santa Fe. Taking advantage of the cabless configuration, the dynamic brake equipment on the GP60B was moved forward and away from the prime mover. Santa Fe 325–347 were the only GP60Bs. Some of these remain in service with BNSF.

BNSF rebuilt GP60B 347 to a standard GP60 by applying the cab of a Union Pacific SD40-2 to the locomotive in 2010. It was then renumbered to BNSF 170.
