HO RS-3 Locomotive with DCC and Sound AS #45 (ATH-2170)

An HO-scale RS-3 diesel-electric locomotive modeled after the ALCO RS-3, this detailed model brings 1,600 horsepower to a layout in a B-B configuration. It is available in DCC-ready form and in sound-equipped versions that feature SoundTraxx Econami with a cube speaker for authentic engine, horn, and bell sounds. LED lighting, through-etched radiator fans, and cab windows add realism, while a heavy die-cast frame and all-wheel drive with precision gears deliver smooth, quiet operation. Fine details such as metal grab irons, fine-scale handrails, RP25-contoured wheels that operate on all popular track brands, and McHenry scale knuckle couplers enhance authenticity. Fully assembled and ready to run, the RS-3 carries road name AS 45 for period-accurate identification.

On HO layouts, it performs best on modest-radius curves, with a minimum radius of 18 inches and a recommended 22 inches for the smoothest operation. Sound-equipped variants house an onboard DCC decoder with SoundTraxx Econami and a single cube speaker, with operation available in both DC and DCC modes and strong low-speed performance. Many functions are NMRA-compatible and tunable via CV changes, and a CV chart is included to help tailor performance. The model is prototypically painted and printed to match period schemes, ready to run straight from the box and reliable on typical HO layouts.
