Lionel 6-11210 Vision Line Challenger #3967 in the "Valley of Bridges".
I took some time to dust off the older Vision Line Challenger #3967 and compare it to the newest Vision Line Challenger #3977.
Tonight I will install one of Gunrunner John's YLB #10500 Batteries for the sound board in the tender of the #3967 Challenger. The battery helps the Challenger go over my Atlas O switches and Double Cross-over Interlock, providing a few seconds of power to the sound system.
Sincerely, John Rowlen
