Atlas 10003394 HO Alco S2 - Standard DC - Master(R) Silver -- Southern Pacific 1780 (gray, red)

This detailed Atlas HO Scale Master Silver Alco S2 is modeled after switchers built by the American Locomotive Company (Alco). Introduced in 1940 to replace Alco's earlier high-hood switchers, over 1,500 locomotives were produced through 1950. This long-lived line of locomotives used turbocharged 539-series prime movers.The 1000 horsepower S2 was a turbocharged version of the S1. There were 1,502 S2s sold to North American Railroads. The versatility of the S2s was evidenced by their service on class 1 shortline and industrial railroads. 

In 2023 this model was retooled to include more accurate body details. This Atlas model features a five-pole, skew-wound motor with dual flywheels, directional LED lighting, Accumate(R) magnetic knuckle couplers, accurate decoration and roadname-appropriate body details. This diesel comes equipped with an 8-pin DCC socket for easy decoder installation when you're ready.
