In Service: 1975 - Present.

Primary Assignment: Light road and yard jobs. Introduced in 1975 as a replacement for aging GP7s and GP9s, the GP15-1 was better suited to the bigger cars entering service, while the low nose improved forward visibility. EMD required customers to provide a trade-in unit, which supplied traction motors, trucks and main generators, reducing the price. GP15-1s looked like 35 Series engines, but with a "tunnel motor" style radiator. Later versions included the GP15-1AC with an alternator and the GP15T, a turbocharged AC model. Nearly 370 were built between 1976 and 1983, and many are still going strong.
