HO DDA40X Locomotive UP #6900 with ICC Caboose #25717 (ATHG71520)

HO-scale Union Pacific DDA40X Centennial locomotive with ICC caboose is a detailed, ready-to-run model designed to bring UP’s famous twin-engine power to HO layouts. It faithfully reproduces the DDA40X’s massive twin-engine profile and its patriotic Bicentennial livery, while including period-accurate features such as illuminated truck lights, classification lights, and lit number boards, along with see-through walkways and MU hoses for authentic operation. The set is available in both DC and DCC configurations, and the included ICC caboose carries a DCC light decoder so its markers illuminate on either control system.

Under the shell sits a heavy die-cast frame with eight-wheel drive and all-wheel electrical pickup for steady, quiet pulling on standard HO curves. Inside, a full cab interior and see-through cab windows, plus fine-scale Celcon handrails, fuel-tank detailing, and other prototypical touches contribute to a convincing presence on the rails. LED lighting provides crisp visibility, while a DCC-sound version uses a SoundTraxx Tsunami2 decoder with four speakers for authentic engine, horn, and bell sounds; the DCC-ready variant accepts decoders for customized control. The model is offered in Legendary Liveries and is primed for grime, giving hobbyists a ready-made starting point to weather and customize an in-service UP locomotive.
