These six-axle hood unit road switchers, nicknamed Train Masters, were deployed in the United States and Canada during the 1950s. They were the successor to the ultimately unsuccessful Consolidated line of cab units produced by F-M and CLC in the 1950s. Each locomotive produced 2,400 horsepower (1.8 MW). In common with other F-M locomotives, the Train Master units employed an opposed piston prime mover. The model rode on a pair of drop equalized three-axle "Trimount" trucks giving it a C-C wheel arrangement. OverviewTouted by Fairbanks-Morse as "...the most useful locomotive ever built..." upon its introduction in 1953, the 2,400 horsepower (1.8 MW) H-24-66 Train Master was the most powerful single-engine diesel locomotive available at the time, legendary for its pulling power and rapid acceleration. No competitor offered a locomotive with an equal horsepower rating until ALCO RSD-7 entered production in January 1954 (EMD followed suit later in July 1958 with SD24, and GE introduced their U25C in September 1963). While some railroads saw advantages in the Train Master's greater power, the perception on the part of others that the unit had too much horsepower (coupled with the difficulties inherent in maintaining the opposed-piston engine, inadequacies in the electrical system, and a higher-than-normal consumption of cooling water) contributed to poor marketplace acceptance of the Train Masters. Both F-M and CLC ultimately left the locomotive business. VariationsThree different carbody variants were produced, and were differentiated as follows: Phase 1a units had their air intake louvers located in a continuous line along the top of the long hood, and a wide separating strip between the radiator fans; Phase 1b modifications were minor, consisting only of a "dip" in the long hood handrails that allowed them to better follow the profile of the side walkways; Phase 2 units boasted fewer air intake louvers, with large gaps separating them (the radiators themselves were divided by only a tiny metal strip). Units manufactured by Fairbanks-Morse (1953–1957)
Units manufactured by the Canadian Locomotive Company (1956)
PreservationOnly one Train Master locomotive has survived intact — former Canadian Pacific Railway (CPR) H-24-66 #8905 is now owned by the Canadian Railroad Historical Association, which operates the Canadian Railway Museum in Saint-Constant, Quebec. Former Norfolk and Western Railway Train Master slugs survived well into Norfolk Southern service with one currently preserved at the Reading Railroad Heritage Museum in Hamburg, Pennsylvania.
