It reproduces the Challenger’s distinctive four-axle leading truck, two sets of driving wheels, and four trailing wheels, delivering a faithful sense of Union Pacific’s wartime mainline workhorse. The coal-burner variant features dual smokestacks and tender bunker coal extensions, representing the 1940s through the 1950s era.\u003c\/p\u003e\n\t\u003cp\u003eInside, a tender-mounted DCC decoder with SoundTraxx Tsunami2 sound delivers authentic engine, whistle, bell and related effects that run in both DC and DCC modes, with full DCC functionality when configured. Dual cube speakers provide robust, immersive sound, while lighting includes illuminated number boards and headlights, a tender back-up light, and a flickering firebox for added realism.

Road-number-specific features for this UP Challenger include coal-burner configuration, dual smokestacks, and tender bunker coal extensions, reflecting the era from the 1940s through 1959.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Athearn (ATH)","offers":[{"title":"Default Title","offer_id":47632918839348,"sku":"ATHG98975","price":769.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/6653\/8292\/files\/ATHG98975.jpg?v=1774531722","url":"https:\/\/nankinhobby.com\/products\/athg98975","provider":"Nankin Hobby","version":"1.0","type":"link"}
