HO EMD SD40-2 Locomotive with DCC & Sound KCS #684 (ATH-1258)

HO-scale EMD SD40-2 locomotive with DCC and sound in Kansas City Southern livery. This fully assembled, ready-to-run model brings authentic prototype operation to HO layouts, delivering realistic engine sounds, lighting, and smooth pulling power right out of the box.

Built around a heavy die-cast frame with a 5-pole motor and flywheels, it offers reliable traction and quiet operation. The model features all-wheel drive, RP25 wheel contours, and fine-scale details such as see-through cab windows, a detailed fuel tank, wire grab irons, and photo-etch windshield wipers. LED headlights, ditch lights, and beacons add to the realism, while an onboard DCC decoder with SoundTraxx Econami sound provides authentic locomotive sounds on the DCC setup; the unit runs on both DC and DCC and is NMRA-compatible for easy integration. Minimum curve radius is 18 inches, with 22 inches recommended for the best performance.
