HO EMD SD40-2 Locomotive KCS #684 (ATH-1235)

HO-scale EMD SD40-2 Locomotive in Kansas City Southern livery, road number 684. This fully assembled, ready-to-run model faithfully reproduces the Dash-2 freight locomotive and is designed for reliable operation on HO layouts, whether pulling freights on a mainline or building a busy yard scene.

Details include flexible rubber MU hoses, see-through cab windows, a detailed fuel tank with gauges and breather pipes, and finely rendered scale handrails and photo-etch windshield wipers. Lighting features include bi-directional LEDs with headlights and ditch lights, and beacons where applicable to the prototype. A heavy die-cast frame, a 5-pole motor with flywheels, and all-wheel drive with electrical pickup deliver smooth, quiet performance, while RP25 wheels ensure solid tracking on popular HO track. The model is offered in non-sound and sound-equipped versions: non-sound are DCC-ready with a 21-pin NEM plug; sound-equipped variants include onboard DCC with SoundTraxx Econami, a single speaker, and NMRA-compatible CVs to tailor engine, horn, and bell sounds (some functions may be limited in DC). Minimum radius is 18 inches, with 22 inches recommended for best performance on typical HO layouts.
