MTH Union Pacific Challenger. 4-6-6-4 Steam Engine and Tender. This is a very big set and it works great. I think MTH did a great job on this challenger. It just looks right to me. I programmed this unit into my remote and the Proto 2.0 system worked fine. The details of this set show 91.5 scale miles. If your interested in this set (thank you) and would like a screen shot of the odometer reading, please let me know and I can send it over. I think this is the first train I tested that didn’t show a low battery reading. The following are some of the great features of this set. Die Cast Boiler and Tender. The box has some shelf wear, corner creasing and store stickers. Let me know if you have any questions.
