GE 45-ton switcher

The GE 45-ton switcher is a 4-axle diesel locomotive built by General Electric between 1940 and 1956.

Equipment

The locomotive was equipped with two Cummins diesel engines, each driving a GE 1503 generator which, in turn, drove one of the two GE 733 traction motors, one per truck. In early models, the second axle on each truck was driven with side rods. Later models had chain drives inside the trucks that served the same purpose.
A traditional train air brake was optional, but all came with two compressors and a straight-air independent brake. The cabs were spacious for the size of the locomotive. Both the engineer's and fireman's seats were raised almost two feet on platforms, to provide better visibility during switching.

Uses

The GE 45-ton was extremely versatile and many variants existed. It has a high weight to power ratio and good traction, rated to be able to pull 20 loaded freight cars on level track. They were built with a short wheelbase for use in industrial plants, yards, and other places where clearances were tight. Although intended as switcher locomotives, they sometimes served mainline duties, although nearly all had an imposed speed limit of due to the double reduction gearing of their traction motors.
