The engine's massive size and tremendous pulling power have made it one of the most-loved engines among 3-rail operators for nearly half a century.ANTIQUE WORKING- Fairbanks Morse Scale- Model 1124- With Counter Weights. In the world of O gauge railroading, however, the Trainmaster was a hit from the moment it went on the market in the mid-1950's. Ultimately, only 127 Trainmasters were sold to 11 U.S. engine required removal of the top crankshaft and removal or disconnection of the entire top bank of cylinders - which also meant the roof of the locomotive had to come off. Whereas a single bad cylinder in an Electro-Motive diesel could be accessed by pulling off one cylinder head, a cylinder repair in an O.P. Perhaps most important, maintenance was a nightmare.
The top crankshaft proved prone to oil leakage. The bone-jarring railroad environment was much rougher on the motor than a submarine cushioned by an ocean. Ultimately, however, the opposed-piston engine proved ill-suited to locomotive use. For one brief moment, Fairbanks Morse looked like a contender. Emblazoned in bright yellow and red, four Trainmaster demonstrators barnstormed the country and walked away with any consist the railroads threw at them. It was the most powerful single-motored diesel locomotive of its era and had a brawny body to match its bold name. Introduced at the Railroad Manufacturers' Supply Association show that year, FM's new locomotive took the show by storm. engine reached its zenith in the Trainmaster. diesel in fact had several advantages over a conventional motor: less moving parts, terrific acceleration, and about double the horsepower per cylinder. While this sounds like a complex way to build an engine, the O.P. The upper and lower banks of pistons each powered a separate crankshaft, and the two crankshafts were linked together to power the locomotive. Intake and exhaust occurred through holes in the cylinder walls. In the opposed-piston motor, each cylinder had a piston at either end and the combustion chamber in the middle. Navy's World War II submarine fleet and developed a great reputation for reliability the adaptation to railroad equipment during and after the war seemed like a natural transition. FM's unique opposed-piston diesel engine powered about half the U.S. Fairbanks Morse got into the locomotive business because it made submarine engines.
