The Baldwin VO-660 was a diesel-electric locomotive switcher locomotive built by Baldwin Locomotive Works between April, 1939 and May, 1946. The 197,520–203,980 lb (89,600–92,500 kg) units were powered by a six-cylinder diesel engine rated at 660 horsepower (492 kW), and rode on two-axle AAR Type-A switcher trucks in a B-B wheel arrangement. 142 examples of this model were built for American railroads, along with the United States Navy. Baldwin replaced the VO-660 with the model DS-4-4-660 in 1946.
In the early 1960s the Reading Company sent all 10 of their VO-660s to General Motors Electro-Motive Division to have them rebuilt to SW900 specifications. These locomotives received new frames, cabs, and carbodies. Only two intact examples of the VO-660 are known to survive today, one of which was by the Altoona Railroaders Memorial Museum to SMS Lines to be repaired and put back into operation. The other is Pickens Railway #2, built in 1946.
