HO GEN SD50 Locomotive with DCC and Sound, BO #8578 (ATHG-1851)

HO Scale Genesis EMD SD50 Locomotive with DCC and Sound in Chessie System/B&O livery is a detailed, ready-to-run HO model that recreates EMD’s 3,500-horsepower SD50 from the early 1980s. It includes a DCC decoder with SoundTraxx Tsunami2 sound for authentic horn, bell, and engine rumble as it runs on your layout, delivering a convincing prototype experience in a classic Chessie/BO paint scheme.

On the rails it combines solid, model-railroader-ready construction with authentic detail: a heavy die-cast frame, all-wheel drive, and a precise 5-pole motor for smooth, quiet operation; full cab interior and see-through cab windows; body-mounted scale knuckle couplers; and LED headlights with operating ditch lights. The DCC version supports full NMRA-compatible functions and runs on both DC and DCC layouts, with dual speakers for richer sound and a Quick Plug 21-pin interface for easy setup, plus a CV chart to fine-tune performance. Authentic Chessie/BO touches such as the Nathan K5 horn, long-hood bell, early-frame styling, and Timken-bearing trucks complete the look for an era-faithful appearance.
