Thanks to the fabled career of #3985, people are most familiar with Union Pacific's 4th order of Challengers. But these locomotives were successors in a long line of locomotives going back to 1936. For our next Brass-Hybrid locomotive, Lionel is proud to showcase an earlier version of this amazing machine. Union Pacific placed its second order for Challengers with Alco in 1937. Classed CSA-2 and numbered 3915-3939, these locomotives built off lessons learned in the first 15 production units and were still purposed for both freight and passenger duty. The CSA-2s were converted to oil-burners and in 1944 renumbered into the 3800 series. Over the decades, shop forces made many other modifications; the most visible of which were in the pilots, stacks and sandboxes. Lionel is offering this class with three different detail variations, each in two accurate road numbers and an un-numbered version for those who want a unique number or a starting point to customize the model even further. Of course, we'll also be offering an unpainted "pilot" model and two fantasy schemes; one based on the Challenger streamliners and the other the Greyhound paint scheme which was applied to the larger Challengers but not this class. All of the models presented are appropriate for their appearance after the 1944 oil conversion and renumbering. Detail variations include pilot, sand dome and running gear changes. In addition to unparalleled detail, these models will also feature 4-digit addressing capability with the Cab 3 App, road-number specific crew talk, whistle steam and a three-speaker sound system. Never before have these locomotives been available in O scale with this level of control, features and detail. A must for any Union Pacific fan or anyone who loves big steam power, with a unique look unlike the later Challengers, these models will not be around long nor offered again. So don't miss your opportunity to step up to the Challenger!
