Built by the General Motors Electromotive Division as a replacement of the SW1200, the SW1500 was intended for switching (shunting) duties, and was capable of light branch line work as a road switcher. It was a development of the SW1200 and previous SW-series switchers dating back many years earlier, and was fitted with a 1500 horsepower two-stroke V-12 diesel engine.

A total of 808 examples were built from 1966 to 1974, serving industrial and railroad operators across the length and breadth of the United States, with approximately a quarter of the whole production initially purchased by the Southern Pacific Railroad. A huge number of SW1500s can still be found in use today, proving the durability and versatility of this old locomotive design.
