Atlas Master 10003836 ALCo S4 Diesel Locomotive Pennsylvania PRR 8434 DCC & Sound

This detailed Atlas HO Scale Master Gold Alco S2 is modeled after diesels built by the American Locomotive Company between 1949 and 1957. The 1,000-horsepower diesel-electric switchers were designed to replace older steam switchers. Almost 800 S4s featured a six cylinder 539 prime mover and rode on AAR Type A Trucks (which distinguished them from nearly identical S2s). Whether operated by their original owners or secondary owners, several of these venerable workhorses are still working in the 2020s and others are preserved in museums or on excursion railroads. 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 replica comes equipped with a dual-mode ESU LokSound sound and DCC decoder for operation on DCC and DC layouts (with limited sound capabilities on in DC operation).

• Newly tooled with improved cab design
• 5-pole skewed armature motor for reliable operation
