The Big Boy's were designed to pull heavy freights up the Wasatch Range in Utah to the division point at Green River, WY. What was needed was a locomotive to take over at that point that could speed the freights eastward across the Wyoming Division. Building on their experience with the original CSA 4-6-6-4 Challengers UP and Alco's designers developed a newer and better Challenger type locomotive. The result was a group of 65 4-6-6-4 Challenger built in three separate groups during World War II. \u003cbr\u003eROAD NUMBER 3997 SPECIFIC FEATURES: :\u003cbr\u003eCoal Burner\u003cbr\u003eDual smoke stack\u003cbr\u003eTender bunker coal extensions\u003cbr\u003eEra 1940's - 1959\u003cbr\u003eSTEAM LOCOMOTIVE FEATURES: \u003cbr\u003eDCC-ready features Quick Plug™ plug-and-play technology\u003cbr\u003eScaled from prototype resources including drawings, field measurements, photographs, and more\u003cbr\u003eAccurately-painted and –printed paint schemes\u003cbr\u003eFull cab interior with boiler backhead with printed gauges\u003cbr\u003eIndividually applied piping, valves, generators, etc.\u003cbr\u003eOperating eccentric cranks on both sides operating in correct direction\u003cbr\u003eHeadlights and indicator number boxes (number boards) with directional light change\u003cbr\u003eFive pole, skewed armature motor with flywheel for smooth operation\u003cbr\u003ePivoting front and rear engines for negotiating 11\" radius curves\u003cbr\u003eSee-through running boards\u003cbr\u003eSee-through cab windows\u003cbr\u003eMcHenry® scale knuckle couplers\u003cbr\u003eLED Lighting for realistic appearance\u003cbr\u003eFully-assembled and ready-to-run\u003cbr\u003eHeavy die-cast frame for greater traction and more pulling power\u003cbr\u003ePackaging securely holds for the model for safe storage\u003cbr\u003eMinimum recommended radius: 15\"\u003cbr\u003eSOUND EQUIPPED MODELS ALSO FEATURE:\u003cbr\u003eTender-mounted DCC decoder with SoundTraxx Tsunami2 sound\u003cbr\u003eSound, units operate in both DC and DCC\u003cbr\u003eFull DCC functions available when operated in DCC mode\u003cbr\u003eEngine, whistle, and bell sounds work in DC\u003cbr\u003eAll functions NMRA compatible in DCC mode\u003cbr\u003eExcellent Slow speed control\u003cbr\u003eMany functions can be altered via Configuration Value (CV) changes\u003cbr\u003eCV chart included in the box\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Factory New (\u003ca href=\"#\" title=\"C-9: All original; unused; factory rubs and evidence of handling, shipping and factory test run.
