FAIRBANKS-MORSE H10-44 (FS10 PRR's class) yard-switcher diesel-electric locomotive



The Fairbanks-Morse H10-44 was a yard switcher locomotive produced through 1944-1950 and was the first diesel electric switcher locomotive put into service line. The units featured a 1,000-horsepower (750 kW) six-cylinder 38D8 opposed piston (O.P.) engine prime mover, and were configured in a B-B wheel arrangement.
The H10-44 was originally meant to be used only in yard service. However, as is so often the case in the industry, railroads found that the model could be utilized in all types of work from yard service to branch line duty. A total of 195 units were built for many american railroads (Class 1 and smaller companies), for example Baltimore & Ohio, Chicago & North Western, Chicago Milwaukee St. Paul & Pacific, New York Central, Atkinson Topeka & Santa Fe, Union Pacific.
Thereafter some new models were developed with more powerful engines (as the H12-44 engine with 1200 horsepower), maintaining the same external drawing carbody.
The Pennsylvania Railroad bought 55 units (primary user of this model), placed in service between June 1948 and November 1949. All units were used as yard switcher, until the end of sixty years.
