At the time the Fairbanks Morse Trainmaster was introduced and produced, it was the most powerful diesel locomotive on the market

Using Fairbanks-Morse's opposed-piston engine, the H24-66, it produced 2,400 horsepower directed towards 2 6-wheel trucks

With 2,400 horsepower it offered double the horsepower of the F3 and the promise was could pull twice as much for the same maintenance costs

They did the job well

The Lackawanna was the first railraod to get the FM's, in 1953, and Lionel cataloged their 1st model (The Lackawanna) in 1954

1 a minute rolled off the Lionel assembly line for 2 shifts a day (16 hours) for nearly 2 years.

Lionel's model with 2 motors is one of the most powerful and handsome Lionel Locos of all time
