locale=North America The ALCO RS-2 is a convert|1500|hp, B-Broad switcher railroad locomotive . It was manufactured byAmerican Locomotive Company (ALCO) from October1946 to May1950 , and 383 were produced — 366 by theAmerican Locomotive Company , and 17 byMontreal Locomotive Works inCanada . It has a single, 12 cylinder, model 244 engine, devoloping convert|1500|hp. Thirty-one locomotives built by Alco between February and May 1950 had convert|1600|hp engines.ALCO built the RS-2 to compete with EMD,
Fairbanks-Morse , andBaldwin Locomotive Works . In1947 , Fairbanks-Morse introduced the 1,500 hp (1.2 MW) H-15-44. Also in that year, Baldwin introduced the 1,500 hp (1.125 MW) DRS-4-4-1500. 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 (1.125 to 1.2 MW), and added more improvements to create new locomotive lines.EMD, however, kept its competing GP7 at 1,500 hp (1.125 MW) In
1954 , EMD introduced the GP9. It was rated at 1,750 hp (1.3 MW).EMD produced 2,729 GP-7s. ALCO produced 383 RS-2s, and 1,370 RS-3s. Fairbanks-Morse produced 30 H-15-44s, and 296 H-16-44s. Baldwin produced 32 DRS-4-4-1500s, and 127 AS-16s.
