The RSC-3 was introduced in 1950 as the RS-3's light axle counterpart, and as the successor to the RSC-2. As with the RS-3, the RSC-3 was a very durable locomotive, the only real issue being the GE turbocharger, which also like the RS-3, was phased out of production as soon as a suitable replacement was developed. With the demand for lighter axle loading in the United States all but gone (mostly due to the shortcomings of an A1A-A1A wheel arrangement versus a C-C wheel arrangement), only a handful were built for the domestic market, and most RSC-3s were built for the export market with Australia and Pakistan being largest buyers. Due to being mostly built for railroads outside of North America, many soldier on today, with at least a dozen still in revenue service.

Notes
(1): Later units were built with a 12-244G, 12-244H, or rebuilt with a 12-250.
(2): Often RSC locomotives had their idlers removed or trucks replaced with AAR Type B's, making the axle count four.
(3): Very late units had a Max TM Current and DB Max Current of 1800 Amps, and a Gen Max Current of 3600 Amps.
(4): "Automatic with Selector" was optional.
(5): Very late units had Mechanical Blowers @ 50%
(6): In later production A high capacity brake grid was optional, raising the max continuous of 800 Amps.
(7): 24-RL was optional.
(8): 307 and 450 CFM compressors were available.
(9): If equipped with the 2000 gallon fuel tank, the reservoir capacity is raised to 35.24 Cubic Feet.
