The ALCO RSD-5 is a diesel-electric locomotive rated at 1,600 horsepower (1.2 MW), that rode on a pair of three-axle trucks, having a C-C wheel arrangement. Basically an upgraded version of the earlier ALCO RSD-4, and used in much the same manner as its four-axle counterpart, the ALCO RS-3, the six-motor design allowed better tractive effort at lower speeds.
