FM H-10-44 Diesel-Electric Locomotive
The FM H-10-44 was a yard switcher produced by Fairbanks-Morse from August, 1944–March, 1950. The units featured a 1,000-horsepower (750 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. Many H-10-44s received modifications that increased their horsepower rating to 1,200 hp (890 kW).

The Raymond Loewy-designed carbody featured a slanted nose, sloping hood lines, and (considered to be its most distinguishing feature) a protruding roof visor mounted on the rear of the cab. These styling cues were carried through to the H-10-44's successor, the FM H-12-44, until September 1952 when the exterior design was "Spartanized" to reduce production costs.

A total of 195 units were built for American railroads. Three intact examples of the H-10-44 are known to survive today, all of which are owned by railroad museums. Most notable of these is Milwaukee Road No. 760 (originally delivered as No. 1802), the first Fairbanks–Morse locomotive constructed in their own plant, which is preserved and on display at the Illinois Railway Museum.

Another example is former Hallet Dock Company HD-11, which is now at the Lake Superior Railroad Museum in Duluth, Minnesota.

A reproduction H-10-44 locomotive sits atop the Beloit Fishing Bridge, a former railroad bridge which crosses the Rock River several hundred yards south of the foundry where the H-10-44s were built, in Beloit, Wisconsin.
