ALCO RSD-5
The ALCO RSD-5 is a diesel-electric locomotive rated at, 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.
