Diesel Roadswitchers for Transition-Era Railroads

The RS-2 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 RS-3 in 1950 (although a few late RS-2s were rated at 1,600 horsepower).

RS-2s 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.

These detailed locos feature a heavy diecast chassis,factory-installed 9-pin DCC harness, 14:1 gear ratio helical-cut gears for quiet operation and easy multiple unit operation with PROTO 2000 locos, a five-pole skew-wound motor, all-wheel drive and electrical pickup, dual machined brass flywheels, RP-25 contour blackened wheels and magnetic knuckle couplers. Each engine is equipped with constant and directional headlights.
