The 24.3/info/h" target="_blank">H-24-66, or Train Master, was a diesel-electric railroad locomotive produced by Fairbanks-Morse and its licensee, Canadian Locomotive Company. These six-axle hood unit road switchers 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. It rode on a pair of drop-equalized three-axle "Trimount" trucks, giving it a C-C wheel arrangement.




Overview


Advertised by Fairbanks-Morse as "the most useful locomotive ever built" upon its introduction in 1953, the 2,400-horsepower (1.8 MW) 24.3/info/h" target="_blank">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 the ALCO RSD-7 entered production in January 1954. EMD followed suit later in July 1958 with the SD24, and GE introduced their U25C in September 1963.
While some railroads saw advantages in the Train Master's greater power, others thought the unit had too much horsepower. Other drawbacks were the difficulties inherent in maintaining the opposed-piston engine, inadequacies in the electrical system, and a higher-than-normal consumption of cooling water. All these contributed to poor marketplace acceptance of the Train Masters—and ultimately the departure of F-M and CLC from the locomotive business.




Variations


Three carbody variants were produced. Phase 1a units had air intake louvers in a continuous line along the top of the long hood and a wide separating strip between the radiator fans. Phase 1b had a "dip" in the long hood handrails that allowed them to better follow the profile of the side walkways. Phase 2 units had fewer air intake louvers, with large gaps separating them, and the radiators themselves were divided by a tiny metal strip.

Preservation


Only one Train Master locomotive has survived intact: former Canadian Pacific Railway (CPR) 24.3/info/h" target="_blank">H-24-66 #8905, which is now owned by the Canadian Railroad Historical Association, which operates the Canadian Railway Museum in Saint-Constant, Quebec.
Some former Virginian Railway Train Masters were rebuilt into slugs by the Norfolk and Western Railway; they survived well into Norfolk Southern service. One is preserved at the Reading Railroad Heritage Museum in Hamburg, Pennsylvania.
