what is it?
The FM H-12-44TS was a light road switcher version of the Fairbanks-Morse H-12-44 yard switcher locomotive. Only three of the 1,200-horsepower (890 kW), six-cylinder opposed piston engine locomotives (builder numbers 12L1021–12L1023) were manufactured especially for the Atchison, Topeka and Santa Fe Railway in May, 1956. The units had an extended frame to accommodate the addition of a short hood behind the cab, and were configured in a B-B wheel arrangement and mounted atop a pair of two-axle AAR Type-A switcher trucks with all axles powered.
