The RS2 was Alco's first roadswitcher to incorporate its new 244-Series prime mover. The 1,500-horsepower units were designed for versatility they were equally at home working road freights or switch runs. If equipped with a steam generator, they were adept at working commuter and secondary passenger runs. Production began in 1946 with just over 350 units constructed for U.S. and Canadian roads before the unit was succeeded by the 1,600-horsepower RS3 in 1950 (although a few late RS2s were rated at 1,600 horsepower).
RS2s have worked for Class I, shortline and industrial lines across the continent. The engines have been long lived, with one survivor still holding down daily freight duties in 2007. A few others still see service at museum and tourist lines.
