  • Prototype and Background Info:
  • ALCO built the RS-3 to respond to competition with EMD, Fairbanks-Morse, and Baldwin Locomotive Works. In the case of ALCO, the builder added more improvements to create new locomotive lines beyond the RS-2. ALCO produced 377 RS-2s versus the more successful RS-3s at 1,418.
  • The new model produced slightly more horsepower than the earlier design at 1,600 hp using Alco’s 12-cylinder, model 244 prime mover. Visually, the RS3 very similar to the RS2. Both had much more styling then ALCO’s first diesel, the RS1. Additional curves with strong beveling to corners and edges giving the unit a much more streamlined appearance. At the time, some railroads elected to employ theirs RS3 diesels in passenger/commuter service. Many railroads appreciated this model for its versatility and reliability. RS3s were one of Alco’s shops more popular locomotives.
