Fairbanks-Morse "C-Liner" to be exact. the B-B (Bo-Bo or whatever you want to call it) version to be exact.
Note: I specify B-B wheel arrangement because there was another variant that had a B-C (Bo-Co) arangement with a six-axle truck under the rear to support the weight of a steam-heat boiler and its water tank.
Wrong Model name, it's ether a CFA-16-4 or a CFA-20-4, first one has 1600hp and the other 2000hp. I will be making one soon as I have made the CFA-24-5 that is the B-C one.
