The RSC-2 was the successor to the RSC-1 and the predecessor of the RSC-3. Designed as a high horsepower replacement of the RSC-1 and as a lighter axle loading version of the RS-2. Like it's four axle counterpart, many were rebuilt in the 50s with much improved 244 engines, increasing their lives exponentially. Often being retrucked by AAR Type B's, many lasted into preservation, leaving five around in original condition.

Notes
⚠: Not Verified or Educated Guess
(1): Later units were built with A, B, or C blocks. Many units were also rebuilt with D, G, and H blocks.
(2): Very late units built with 12-244C engines have a horsepower rating of 1600.
(3): Often RSC locomotives had their idlers removed or trucks replaced with AAR Type B's, making the axle count four.
(4): Later RSC-2s used the Alco A1A Late.
(5): Units built after June 1947 are equipped with GE 752s and would have a Max TM Current of 1500 Amps, a Max Continuous Current of 900 or 1085 Amps, and a Generator Max Current of 3000.
