HO SD75M Locomotive with DCC and Sound ATSF #220 (ATHG71228)

This HO-scale Santa Fe SD75M locomotive with DCC and sound (road number 220) brings Santa Fe’s late-1990s power to the layout with authentic detailing and operation. It features an on-board DCC decoder and SoundTraxx Tsunami2 sound, delivering engine, horn, and bell audio that respond to throttle and direction in both DC and DCC modes, with full DCC functionality and precise slow-speed control. Built on a heavy die-cast frame with a five-pole skew-wound motor, it offers smooth, quiet pulling power, while see-through cab interiors, fine Celcon handrails, and LED lighting enhance realism. Body-mounted scale knuckle couplers compatible with Kadee, RP25 wheels, and a 21-pin NMRA DCC connector ensure straightforward setup, and the Santa Fe Superfleet-inspired livery with round ditch lights and a large Sinclair antenna captures the prototype look.

Prototype accuracy meets practical operation on HO layouts: the SD75M reproduces Santa Fe’s 1994-order power with about 4,300 horsepower and a subtly larger body than the SD70M. The model is DCC-ready with CV-programmable functions and a CV chart included for reference, allowing operators to tailor speed, lighting, and sound. For layout versatility, it supports a minimum radius of 18 inches (22 inches recommended), delivering reliable performance on a wide range of layouts and enabling confident hauling of longer trains.
