HO EMD SD40-2 Locomotive with DCC and Sound WAMX #4170 (ATH-1267)

HO-scale EMD SD40-2 Locomotive with DCC and Sound, road number WAMX 4170, is a ready-to-run HO model that captures the iconic Dash-2 locomotive for HO layouts. It includes a DCC decoder and SoundTraxx Econami sound system driving a single speaker, delivering authentic engine, horn, and bell sounds in both DC and DCC operation. Lighting features include LED front and rear headlights, ditch lights, and beacons where applicable, and the model rides on a heavy die-cast frame for traction and rugged performance.

Designed for faithful operation, the SD40-2 showcases all-wheel drive with a precision-geared drivetrain, a five-pole motor with flywheels, and RP25-contoured wheels for smooth tracking on most HO track. Fine detailing includes see-through cab windows, scale handrails, and other period-correct touches, with McHenry operating scale knuckle couplers for reliable coupling. The onboard DCC decoder keeps the model NMRA-compatible in DCC mode, and CV adjustments allow tailoring of sound and lighting and the creation of MU lashups; a CV chart is included to help with setup. Packaging securely holds the model for safe storage, and a minimum radius of 18 inches (22 inches recommended) ensures smooth performance on standard layouts.
