The ALCO RSC-3 was a diesel-electric locomotive of the road switcher type rated at 1,600 horsepower (1,200 kW), that rode on three-axle trucks, having an A1A-A1A wheel arrangement.^[1]

Used in much the same manner as its four-axle counterpart, the ALCO RS-3, though the axle load was spread out for operation on light rail such as are found on branch lines. This locomotive had much better success as an export unit than in the domestic market.
