HO SD40-2 Locomotive with DCC and Sound BNSF Rebuilt #7333 (ATH73731)

This HO-scale SD40-2 locomotive in BNSF rebuilt livery is built for authentic operation on HO layouts. It includes a DCC decoder with onboard SoundTraxx Econami sound and a single-cube speaker that delivers engine, horn, and bell sounds. Sound units operate in both DC and DCC modes, with full functionality in DCC and some features limited on DC. The model uses a 21-pin NEM plug-and-play interface for easy decoder upgrades and is designed to negotiate typical hobby curves with a minimum radius of 18 inches and 22 inches recommended for smooth performance.

Beyond its sound, the locomotive is richly detailed for visual realism: LED lighting, photo-etched windshield wipers, and appropriately modeled grab irons, air tanks, and handrails. It rides on Flexicoil-C trucks with McHenry scale knuckle couplers and RP25 wheel contours for compatibility with most popular track brands, while a robust 5-pole skew-wound motor with flywheels delivers smooth, quiet operation. With all-wheel drive and electrical pickup, this model offers dependable power on busy layouts and is well suited for long consists and dynamic operations on HO scales.
