The ALCO RSD-4 was a diesel-electric locomotive of the road switcher type rated at 1,600 horsepower (1.2 MW), that rode on three-axle trucks, having an C-C wheel arrangement.
Used in much the same manner as its four-axle counterpart, the ALCO RS-3, though the six-motor design allowed better tractive effort at lower speeds. Due to the inadequate capacity of the main generator, this model was later superseded in production by the ALCO RSD-5
