The EMD GP60 is a model of 4-axle (B-B) diesel-electric locomotive built by General Motors Electro-Motive Division between 1985 and 1994.

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.

Taking advantage of the cabless configuration, the dynamic brake equipment on the GP60B was moved forward and away from the prime mover.

Some of these remain in service with BNSF; one of them, GP60B 347, was rebuilt into a standard GP60 by applying the cab of a Union Pacific SD40-2 to the locomotive in 2010.

Nearly half of the SP Fleet was lettered for subsidiary Cotton Belt, but an even hundred were directly Southern Pacific.

Two units built for the Texas Mexican Railway were returned to lessor Helm Financial after Kansas City Southern acquired the "Tex Mex".
