The FM H-12-44 was a yard switcher produced by Fairbanks-Morse from May, 1950–March, 1961. The units featured a 1,200-horsepower (890 kW), six-cylinder opposed piston engine prime mover, and were configured in a B-B wheel arrangement mounted atop a pair of two-axle AAR Type-A switcher trucks, with all axles powered and geared for a top speed of 60 miles per hour (97 km/h).
A total of 303 units were built for American railroads, 30 were manufactured (between August 1951 to June 1956) by the Canadian Locomotive Company for use in Canada, and 1 unit was exported to Mexico. Initially, H-12-44s were visually indistinguishable from their predecessor model, the FM H-10-44. However, beginning in September, 1952 the Raymond Loewy design elements were removed as a cost-saving measure: cab lines were squared-off, the slanted-nose styling was discontinued, and the roof visor was eliminated. The following year, the fairing over the battery box was removed and louvers added to reduce the possibility of battery explosions. None of the units were produced between May and October 1956, after which time the carbodies were shortened by some three feet and outfitted with a deeper side skirt.
Sixteen intact examples of the H-12-44 are known to survive today, all of which are owned by railroad museums or historical societies.
one H-12-44TS, Santa Fe 543, now resides at the Illinois Railway Museum.

Preservation
Several examples of the H-12-44 model have been preserved around the US and Canada.
- US Army # 1843 is a part of the collection at the Rochester & Genesee Valley Railroad Museum in Rush, NY (south of Rochester, NY). It is in operable condition and is a key locomotive at the RGVRRM.
- US Army #s 1850, 1853, and 1861 are stored out of service at the Heart of Dixie Railroad Museum in Calera, Alabama.
- US Army #1855 owned and operated (on excursion train) by Nevada State RR Museum, Boulder City, NV
- Weyerhaeuser Timber Company, #1 is preserved at the Northwest Railway Museum in Snoqualmie,Washington. While still being occasionally run after undergoing a full rebuild and engine overhaul. The locomotive is now ran for special events with its partner caboose White River Logging Company number 001 but is not run for regular service.
- Former U. S. Army 1857 is preserved at the Western Pacific Railroad Museum at Portola, CA. It was used at the Sierra Army Depot at Herlong, CA, located along the former Western Pacific Railroad. It is used in the museum's famous "Rent-A-Locomotive" program.
