The RS-2 was the successor to the RS-1 and the predecessor of the RS-3, often being overshadowed and forgotten because of the latter. Designed as a high horsepower replacement of the RS-1 and as a road switcher counterpart to the FA-1, it's only short coming compared to it's full width stablemate was the inability to equip dynamic brakes. A overall solid design, many were rebuilt in the 50s with much improved 244 engines, increasing their lives exponentially. Unfortunately, even though a rugged and durable design, many were scrapped in the late 1990s and 2000s, leaving only seven remaining in the current day.

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): 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.
