Union Pacific 4-6-6-4 Challenger #3997 with DCC and Sound (ATH25745)
Union Pacific 4-6-6-4 Challenger No. 3997 is a detailed N-scale locomotive with DCC and sound, built to run and look like UP’s famous Challenger on a modern layout. This road-number specific model captures the 1940s-era coal-burner configuration, including dual smokestacks and tender bunker coal extensions for authentic period detailing.
In addition to its period-accurate cosmetics, the model features a heavy die-cast frame for traction, a five-pole motor for smooth pulling power, see-through running boards and cab windows, LED lighting, and McHenry scale knuckle couplers. The tender houses a DCC decoder with SoundTraxx Tsunami2 sound, delivering engine, whistle, and bell effects that operate in both DC and DCC modes with full DCC functionality. DCC-ready Quick Plug connectors simplify setup, and a CV chart is included for fine-tuning performance. Designed for layouts with a minimum 15-inch radius curves, this ready-to-run Challenger brings mid-century UP operations to life on the rail.
