Lionel O 2331192 BTO Legacy Challenger, Union Pacific #3826

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.
