Baldwin RS-4-TC

The Baldwin RS-4-TC was a diesel-electric switcher locomotive built by Baldwin-Lima-Hamilton between July 1953 and January 1955. It used a supercharged twelve-cylinder diesel engine rated at 400 horsepower and rode on two two-axle trucks in a B-B wheel arrangement. Seventy-four were built, mainly for the Army with a few for the Air Force. Two numbering systems exist: the 1200 series for domestic service with fixed-axle standard gauge trucks, and the 4000 series for foreign service with adjustable-gauge trucks, although very few of the 4000s went overseas. Most were stored after the Korean War, and many now serve tourist and shortline railroads, some rebuilt in the 1980s as RS-4-TC 1A locomotives.
