The H-24-66 was a diesel-electric railway locomotive model produced by Fairbanks-Morse and its Canadian licensee, the Canadian Locomotive Company. These six-axle hood unit road switchers, known as Train Masters were deployed in the United States and Canada during the 1950s. Each locomotive produced 2,400 horsepower (1.8 MW). They were the successor to the ultimately unsuccessful Consolidated line of cab units produced by F-M and CLC in the 1950s.
