Walthers N: Proto EMD SW9/1200 Locomotive, Canadian National #7022

By 1954 railroads were buying diesels as fast as EMD could build them, and customer demand for more powerful units carried over into the switcher market as well. With the introduction of the new 567C prime mover that year, EMD rolled out its new 1200-horsepower SW9/1200 model which shared the same basic body (with minor variations) and power rating with its predecessor, the SW9 (which had a 567B prime mover). SW9/1200s were produced through 1966 when earlier GPs began taking over yard chores, but these later SW models lead long lives with many still serving shortline and industrial roads long after "retirement" by the original owners.
