The '''FM H-10-44''' was a [[switcher locomotive]] produced by [[Fairbanks-Morse]] from August, 1944&ndash;March, 1950. The units featured a {{convert|1000|hp|adj=on}}, six-cylinder [[opposed piston]] [[Prime mover (locomotive)|prime mover]], and were configured in a [[AAR wheel arrangement#B-B|B-B]] wheel arrangement mounted atop a pair of two-axle [[Association of American Railroads|AAR]] [[AAR type A switcher truck|Type A trucks]], with all axles powered. Many H-10-44s received modifications that increased their horsepower rating to {{convert|1200|hp|abbr=on}}.

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 [[United States|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]] #760 (originally delivered as #1802), the first Fairbanks&ndash;Morse locomotive constructed in their own plant, which is preserved and operational 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]]. 

In 1954, Milwaukee Road H-10-44 #1811 (Now 781) and Milwaukee Road “ribside” caboose #01900 wrecked between Monticello and New Glarus, Wisconsin. A wooden rail bridge had been previously burned in a grass fire, and both the locomotive and caboose struck the bridge. Both are now restored and on display at the Brodhead Historical Society in Brodhead, Wisconsin. 

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