HO SD40 Locomotive with DCC and Sound, C&O #7459 (ATH73741)

HO-scale SD40 locomotive with DCC and sound in Chesapeake & Ohio livery number 7459. This detailed model brings the classic EMD SD40 to the layout, designed for realistic yard and mainline operation. It includes an onboard DCC decoder with SoundTraxx Econami sound, delivering engine, horn, and bell sounds that operate in both DC and DCC modes.

Prototype-grade detailing and a smooth, quiet drive come standard: LED lighting, photo-etched windshield wipers, wire grab irons and air tanks, see-through cab windows, and a detailed 4000-gallon fuel tank are faithfully reproduced on a highly detailed injection-molded body. The drive uses a 5-pole skew-wound motor with flywheels and precision gearing for smooth operation, and RP25 wheel contours provide dependable performance on most tracks. McHenry scale knuckle couplers are Kadee-compatible, and Quick Plug technology with a 21-pin NEM connector keeps wiring easy for DCC setups. The model supports MU lashups and CV tuning, offers NMRA-compatible DCC functionality, and features operating lighting. Minimum radius is 18 inches, with 22 inches recommended for best performance.
