Combining theaccessibility of a switching locomotive and the higher-speed tracking of a road unit, the RS-1 started a revolution in locomotivedesign that was soon embraced by all of the major diesel-electric builders. Despite ALCOs own introduction of higher horsepowerroadswitchers, the 1,000 h.p. RS-1 had a production span of 19 years (1941-1960) with 623 units.
