HO SD40 Locomotive with DCC and Sound (CR/PC Patched #6261) (ATH73738)

This HO-scale SD40 locomotive with DCC and sound (CR/PC-patched) is a detailed model designed for HO layouts and railroading enthusiasts seeking authentic North American diesel power. Based on the classic EMD SD40, a 3,000-horsepower turbocharged V16 that entered service in 1966, the model captures prototype details such as LED headlights, see-through cab windows, photo-etched windshield wipers, finely molded handrails, a 4,000-gallon fuel tank, and an exhaust stack, with visible dynamic brake and radiator fans. It rides on curved Flexicoil-C trucks with precise gearing, uses McHenry scale knuckle couplers, and features all-wheel electrical pickup for smooth, quiet operation on a wide range of HO layouts.

Sound-equipped versions include an onboard DCC decoder with SoundTraxx Econami and a single cube speaker for clear audio. The sound system operates on both DC and DCC, with engine, horn, and bell sounds active in DC and NMRA-compatible function control in DCC (some functions may be limited in DC). Quick Plug plug-and-play technology with a 21-pin NEM connector simplifies installation and supports MU lashups with a lead-unit horn and lights. The model uses RP25 wheel contours for broad track compatibility, requires a minimum 18" radius (22" recommended), and combines an injection-molded, highly detailed body with a robust drivetrain for smooth, realistic operation.
