HO RTR SD38 with DCC and Sound Norfolk Southern #3818 (ATH88946)

HO scale ready-to-run SD38 diesel locomotive with DCC and sound in Norfolk Southern livery, road number 3818. This detailed model recreates the 2,000-horsepower EMD SD38 and is ready to operate on HO-scale layouts, delivering a realistic six-axle diesel for everyday railroad scenes.

NS 3818-specific styling includes a black patch with white numbers and a faded paint effect, along with front ditch lights, a rear-mounted Leslie 3-chime horn, a cab roof antenna, a large fuel tank, a prime air conditioning unit, and no plow. The model features a highly detailed injection-molded body with see-through cab windows and separately applied grab irons, plus all-wheel drive, a 5-pole motor with flywheels for smooth, quiet operation, and RP25-contoured wheels for reliable tracking. It is DCC-ready with a 21-pin NEM Quick Plug and, in sound-equipped versions, uses Onboard Econami Sound by SoundTraxx with engine, horn, and bell sounds; bi-directional lighting keeps headlights bright in both directions, and CVs allow configuring MU lashups. A 22-inch minimum radius is recommended for best performance.
