The EMD SD89MAC was a 4,500 horsepower C-C diesel-electric locomotive produced by General Motors Electro-Motive Division. It is, along with the SD80MAC and SD90MAC, one of the largest single-engined locomotives produced by that company, surpassed only by the dual-engined DD series. The SD89MAC featured radial steering trucks and an isolated cab which was mounted on shock absorbers to lessen vibrations in the cab. The SD89MAC was to use AC traction motor technology. Like the SD90MAC, it was a hood unit fitted with a safety cab. Like the SD90MAC before it, the SD89MAC has an enlarged radiator section, nearly the entire width of the locomotive, which along with their size makes them easy to spot.

History

The SD89MAC was intended to be less-powerful version of the SD90MAC, and eventual successor to the SD70 series. A single prototype was built, but generated no orders.
