==Competition==
ALCO built the RS-3 to compete with EMD, Fairbanks-Morse, and Baldwin Locomotive Works. In 1950, Fairbanks-Morse introduced the H-16-44. Also in 1950, Baldwin introduced the Baldwin AS-16. In the case of ALCO, Fairbanks-Morse, and Baldwin, each company increased the power of an existing locomotive line from , and added more improvements to create new locomotive lines. All of this was to be more competitive with EMD. ALCO's line was the RS-2, although 31 were built in 1950 with . Fairbanks-Morse's line was the H-15-44. Baldwin's line was the Baldwin DRS-4-4-1500. EMD, however, kept its competing GP7 at . But in 1954, EMD introduced the GP9. It was rated at .
EMD won the road switcher production race, though. EMD produced 2,729 GP7s. ALCO produced 383 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.
