This road-number specific model captures the 1940s-era coal-burner configuration, including dual smokestacks and tender bunker coal extensions for authentic period detailing.\u003c\/p\u003e\n\t\u003cp\u003eIn 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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Athearn (ATH)","offers":[{"title":"Default Title","offer_id":47574281224244,"sku":"ATH25745","price":499.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/6653\/8292\/files\/ATH25745.jpg?v=1773317273","url":"https:\/\/nankinhobby.com\/products\/ath25745","provider":"Nankin Hobby","version":"1.0","type":"link"}
