HO SD40 Locomotive with DCC & Sound C&O #7457 (ATH73740)

HO SD40 Locomotive with DCC & Sound in Chesapeake and Ohio livery, No. 7457, is a detailed HO-scale model designed for realistic operation on model railroad layouts. Recreating the 1966-era SD40, it delivers 3,000 horsepower from a turbocharged V16 645 engine and includes an onboard DCC decoder and SoundTraxx Econami sound for authentic engine, horn, and bell as you run it.

Details emphasize scale realism and smooth performance: LED lighting, photo-etched windshield wipers, see-through cab windows, and separately applied grab irons and air tanks, plus curved radiator fan grab irons, coupler cut levers, rubber MU hoses, and a detailed 4,000-gallon fuel tank. It rides on Flexicoil-C trucks with RP25 wheel contours and McHenry knuckle couplers for reliable operation, with all-wheel drive and electrical pickup for steady pulling power. The model is DCC-ready with Quick Plug and a 21-pin NEM connector, housing an onboard DCC decoder with a single cube speaker for robust sound that works in both DC and DCC (some functions may be limited in DC). CVs tailor performance, and the minimum radius is 18 inches, with 22 inches recommended for best results.
