The ALCO RS3 is a 1,600 hp (1.2 MW), B-B road switcher diesel-electric locomotive. It was manufactured by American Locomotive Company (ALCO) and Montreal Locomotive Works (MLW) from May 1950 to August 1956, and 1,418 were produced — 1,265 for American railroads, 98 for Canadian railroads, 48 for Brazilian and 7 for Mexican railroads. It has a single, 12 cylinder, model 244 engine.
ALCO built the RS-3 to compete with EMD, Fairbanks-Morse, and Baldwin Locomotive Works. In 1949, EMD introduced the EMD GP7. In 1950, Fairbanks-Morse introduced the 1,600 hp (1.2 MW) H-16-44. Also in 1950, Baldwin introduced the 1,600 hp (1.2 MW) Baldwin AS-16. In the case of ALCO, Fairbanks-Morse, and Baldwin, each company increased the power of an existing locomotive line from 1,500 to 1,600 hp (1.1 to 1.2 MW), and added more improvements to create new locomotive lines.
EMD won the road switcher production race, though. EMD produced 2,729 GP7s. ALCO produced 377 RS-2s, and 1,418 RS-3s. Fairbanks-Morse produced 30 H-15-44s, and 296 H-16-44s. Baldwin produced 32 DRS-4-4-15s, and 127 AS-16s.
Trivia[]
- Conrail adopted and repainted and numbered some of ALCO's RS-3 locomotives, and used them for service, but were eventually retired.
