SUNSET MODELS 3RD RAIL ALCO RS3 LONG ISLAND RAILROAD - 2 RAIL

The ALCO RS-1 and RS-3 are among the most important early road-switchers in American railroading, and no commuter railroad put them to more visible, long-lived service than the Long Island Rail Road. Compact, powerful, and exceptionally versatile, these Alcos became a backbone of LIRR diesel operations from the late 1940s through the 1970s.

On the Long Island Rail Road, RS-1s and RS-3s handled an extraordinary range of duties:

yard switching at Jamaica and Morris Park, local freight service across Long Island, work trains, passenger extras, and branch line assignments where flexibility and reliability mattered most. For decades, these locomotives were a common sight under wire, alongside electrified territory, and across diesel-only branches—making them unmistakably New York railroad icons.

Few railroads applied as many variations of lettering, striping, and numbering practices to a single locomotive class as the Long Island Rail Road. From early black schemes to the familiar gray tones with bold LONG ISLAND lettering, LIRR RS-1s and RS-3s developed a visual identity instantly recognizable to commuters, photographers, and railfans throughout the New York metropolitan area.

These locomotives are especially beloved today for their authentic New York character—working-class power that earned its keep every day rather than headline-grabbing mainline glamour.
