HO RS-3 Locomotive with DCC and Sound, WM #187 (ATH-2167)

HO RS-3 Locomotive with DCC and Sound, WM 187 — a detailed HO-scale diesel-electric model that faithfully reproduces the ALCO RS-3 prototype. Built between 1950 and 1956, the RS-3 delivered 1,600 horsepower in a B-B configuration, and this ready-to-run model captures its period styling and performance for HO layouts.

With a heavy die-cast frame, a five-pole motor with precision flywheels, and all-wheel drive, it delivers smooth, quiet operation and solid pulling power. Realistic details include see-through etched radiator fans and cab windows, metal grab irons, and fine-scale handrails, plus RP25 wheels for compatibility with popular track brands. DCC-ready operation uses Quick Plug technology and a 21-pin NEM connector; sound-equipped variants feature onboard DCC with SoundTraxx Econami and a cube speaker, with operation in both DC and DCC modes and CV-based tuning. LED lighting provides long life and accurate prototype paint schemes depict WM 187. Minimum curve radius is 18 inches, with 22 inches recommended for best performance. Fully assembled and ready to run.
