what is it?

The FM H-10-44 was a switcher locomotive produced by Fairbanks-Morse from August, 1944–March, 1950. The units featured a 1,000-horsepower (750 kW), six-cylinder opposed piston prime mover, and were configured in a B-B wheel arrangement mounted atop a pair of two-axle AAR Type A trucks, with all axles powered. Many H-10-44s received modifications that increased their horsepower rating to 1,200 hp (890 kW).
