F-M had yet to produce a railroad road locomotive, or any locomotive prior to the 1944 switcher which was built several years after its conception all other locomotive producers, except for General Motors (and a few others who manufactured small industrial locomotives), were forced by the government to continue to build reciprocating steam locomotives during much of the war. Milwaukee Road #760 (originally delivered as #1802), the first Fairbanks-Morse locomotive constructed in their own plant, is now preserved and on display at the Illinois Railway Museum. In 1944, F-M began production of its own 1,000-horsepower (0.75 MW) yard switcher, the H-10-44. In 1939, the SLCC placed F-M 800 hp (600 kW) 8 by 10 inches (203 mm × 254 mm) engines in six streamlined railcars, which are known today as the FM OP800. A 5 x 6 powered the plant switcher at F-M's Beloit, Wisconsin manufacturing facility. Louis Car Company, or SLCC, and scrapped in 1953). Additionally, two of the 5 × 6s were placed in an experimental center cab switcher locomotive under development by the Reading Railroad (road #87, built in 1939 by the St. Not long after, the company produced a 300 hp (220 kW) 5 by 6 inches (127 mm × 152 mm) engine that saw limited use in railcar applications on the B&O, Milwaukee Road, and a few other lines. Since 1932, Fairbanks-Morse had specialized in the manufacture of opposed piston diesel engines for United States Naval vessels. A combined total of 165 units (123 cab-equipped lead A units and 42 cabless booster B units) were produced by F-M and the CLC between 19. Individual locomotives in this series were commonly referred to as “ C-liners”. The Consolidated line, or C-line, was a series of diesel-electric railway locomotive designs produced by Fairbanks-Morse and its Canadian licensee, the Canadian Locomotive Company.
