Promoted as “middleweight power with a heavyweight punch,” the GE 70-Ton Diesel was an economical and efficient choice for branchlines and short lines in the late 1940s/early 1950s that wanted a lighter engine than the typical 100- or 120-ton switcher. Featuring True Blast Plus and dual motors with flywheel, our new O Gauge model is packing a similar punch to handle all your switching duties.
