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.

Preserved units[]

As of 2015, there are only two of these (unrebuilt) locomotives known to be in existence. Ex-CNW #1689, formerly owned by Gary Baloun, is currently in operation at the Illinois Railway Museum and repainted in its original Chicago & North Western colors. The other is the former Utah Railway #306, now painted as Nickel Plate Road #324 and owned by Doyle McCormack of the Oregon Rail Heritage Foundation.

Two rebuilt RSD5s (made into RSD-12's) built for the Southern Pacific survive at the Orange Empire Railway Museum (numbers 2954 and 2958).
