HO SD40R Locomotive DCC and Sound SP Kodachrome #7384 (ATH73735)

HO SD40R Locomotive with DCC and Sound in SP Kodachrome livery offers a highly detailed HO-scale model designed to deliver realism and versatility on modern layouts. It includes an onboard DCC decoder with SoundTraxx Econami sound and a single speaker for clear, convincing audio, and it runs on both DC and DCC. Plug-and-play readiness is provided by a 21-pin NEM connector, while LED lighting and other scale details add to the authentic appearance of the prototype on the rails.

Inside, the model pairs high-fidelity detailing with robust drivetrain engineering: a detailed injection-molded shell, curved radiator fan grab irons, photo-etched windshield wipers, and separately applied grab irons and air tanks. It rides on Flexicoil-C trucks with appropriate brake cylinders, features all-wheel drive with precision gears and reliable current pickup, and uses McHenry scale knuckle couplers with flexible MU hoses for authentic lashups. The onboard DCC sound is NMRA-compatible in DCC mode (some functions limited when running on DC), and the locomotive is sized for HO layouts with a minimum radius of 18 inches and a recommended 22 inches for best performance.
