Lionel Union Pacific Challenger. 4-6-6-4 Steam Engine and Tender. Joshua Lionel Cowen Series. This set is gorgeous. I tested this set with my transformer and it is stuck in neutral. The set cycles trough the various sounds (sounds awesome), but the set will not go forward and I don’t know why. The following is some of the great features of this set. Odyssey System for Speed Control. Working Headlight and Marker Light. Separately Controlled Work Lights. Let me know if you have any questions.
