Built 1985-1994, most still in service Primary Assignment: Fast intermodal and light, priority freight; later used in general freight service as well as local and yard work. As computer technology advanced in the 1980s, EMD took a major step forward with the introduction of the new GP60. Directly behind the cab, a trio of onboard microprocessors regulated and ran various onboard systems, replacing complex wiring circuits and relays. Coaxing 3,800 horsepower from its 16-cylinder 710G3A prime mover, the four-axle GP60 was well suited for fast freight service and was often seen on the point of priority trains when new. While the GP60 proved the advantages of computer control, potential buyers were more interested in six-axle power, and EMD focused its development efforts on the bigger units.
