HO EMD SD40-2 Locomotive Union Pacific #8068 (ATH-1225)

HO scale EMD SD40-2 Locomotive in Union Pacific livery, number 8068, is a highly detailed, ready-to-run model designed for HO-layout enthusiasts. It faithfully reproduces the prototype with see-through cab windows, photo-etch windshield wipers, Celcon handrails, and a heavy die-cast frame for authentic presence and traction. Fully assembled and ready to operate, this locomotive offers realistic operation on standard HO tracks, with LED headlights and ditch lights, refined detailing, and McHenry operating scale knuckle couplers for authentic coupling action.

Two configurations are available: a DCC-ready non-sound version with a 21-pin NEM DCC plug, and a sound-equipped variant featuring an onboard DCC decoder with SoundTraxx Econami, a single cube speaker, and NMRA-compatible CVs for flexible control. In DC mode, engine, horn, and bell sounds are available on the sound-equipped model, and many functions are accessible via CVs in DCC. Prototypical detailing includes flexible rubber MU hoses and trainline hose, see-through dynamic brake and radiator fans, a detailed fuel tank with gauges and breather pipes, separately applied air tanks, and photo-etch windshield wipers. RP25 wheel contours, all-wheel drive with precision gears, and bi-directional LED lighting enhance realism and reliability on a wide range of layouts. The minimum operating radius is 18 inches, with 22 inches recommended for best performance; the model is fully assembled and securely packaged for storage.
