N 4-6-6-4 Challenger Steam Locomotive DCC and Sound UP #3985 (ATH25741)

This is an N-scale Union Pacific 4-6-6-4 Challenger steam locomotive model with DCC and sound, recreating UP's Challenger #3985 in a modern excursion-era livery for model railroaders seeking an authentic, feature-rich representation of this iconic locomotive.

Built for realistic operation, the model rides on a heavy die-cast frame and uses a five-pole motor with a flywheel for smooth pulling power. It includes a tender-mounted DCC decoder with SoundTraxx Tsunami2 sound and is DCC-ready with Quick Plug plug-and-play technology, while capable of running in both DC and DCC modes with full DCC functions in DCC. Realistic details include LED lighting, a full cab interior with backhead gauges, see-through running boards and cab windows, and McHenry scale knuckle couplers. Minimum radius is 15 inches, with pivoting front and rear engines to help negotiate curves, and it ships ready to run right out of the box.
