The Engine That Killed Fairbanks-Morse — The Train Master's Fatal Flaw

In 1953 a company that built submarine engines rolled out the most powerful single-engine diesel locomotive in America. The Fairbanks-Morse Train Master made 2,400 horsepower when its rivals made far less, the railroaders who ran it often loved its raw muscle, and it basically invented the high-horsepower six-axle road-switcher that would later dominate the industry. Six years later, Fairbanks-Morse had quit the locomotive business forever. This is how the best diesel of its day lost. The Train Master's engine was an opposed-piston design straight from FM's WWII submarine business: two pistons per cylinder facing each other, no cylinder head, and two crankshafts. It was compact and efficient in a submarine, but on a locomotive it was tall, thirsty, and awkward to service. Worse, it was unfamiliar — and by the 1950s every shop in America was trained and stocked for EMD. This video explains the opposed-piston engine, why the Train Master was genuinely ahead of its time, and the real reason it failed: not weakness, but being different in a market that had already standardized on sameness. We tie it to the Big Boy, the PRR Q2, and the FF1 — the same lesson in steam, electric, and diesel: raw power is the easy part. Corrections built into this video: the Train Master wasn't a bad locomotive — it was arguably the best of its class; "nobody could maintain it" is an overstatement, since lines like Southern Pacific ran them for decades; and FM's death was as much about EMD's market lock-in as the engine itself. One intact survivor remains: Canadian Pacific No. 8905, in Quebec. What's a product you've seen that was clearly the best in its category and still lost to a more boring, standard competitor?
