An EMD GP28 is a 4-axle diesel locomotive built by General Motors Electro-Motive Division between March 1964 and November 1965. Power was provided by an EMD 567D1 16-cylinder engine which generated 1800 horsepower. This locomotive was basically a non-turbocharged version of the EMD GP35. 16 examples of this locomotive model were built for American railroads, 10 were built for Mexican railroads, and five were built for use in Peru.
