The Baldwin DRS-4-4-1500 was a diesel-electric locomotive of the road switcher type rated at 1,500-horsepower (1,100 kW), that rode on two-axle trucks, having a B-B wheel arrangement. It was manufactured by Baldwin Locomotive Works from 1947 until it was replaced in 1950 by the 1,600-horsepower (1,200 kW) AS-16.
Nine railroads bought 35 locomotives, with five railroads later buying the successor model.
