HO DDA40X Locomotive Union Pacific #6900 (ATHG71519)

HO-scale Union Pacific DDA40X Centennial Locomotive, number 6900, is a detailed, ready-to-run replica for HO layouts that captures UP’s iconic double-engine diesel in faithful form. It represents the “Centennial” unit exactly as-delivered, the only DDA40X built without long-hood class lights, and the prototype is preserved on display in Omaha, Nebraska.

On the layout it delivers authentic lighting and detailing—beacon, classification lights, and illuminated number boards—along with working truck lights, see-through walkways, and MU hoses. The model rides on a heavy die-cast frame with eight-wheel drive and RP25-contoured wheels for reliable operation, and is DCC-ready with Quick Plug 21-pin NEM connectors for easy decoder upgrades. Sound-equipped versions add a Tsunami2 decoder with four speakers and full DCC functionality, delivering engine, horn, and bell sounds to bring the locomotive to life on your roster.
