Well, it arrived today! Test ran it, after finally giving up on getting the tender shell back on with the 9V battery in the clip (the cap was so thick it would have never come back off. Soooo, just placed the battery in the clip vertically, and made sure no wires were pinched and screwed it back together, and voila'. Then reprogrammed the Locomotive's TMCC I.D # and fired her up!! Runs, smokes, crew talk tower com all perfect as are coupler on rear of tender.
I did have an issue with it "grinding", so when I went to pick it up gently, sure enough the screw holding the drivers in place was gone. ( it was under the rails). so I lubed both the front and rear set W/ good ole Lionel grease, tightened the screws (thinking of a thin ribbon of loc-Tite) when I officially get it for Christmas. And that took care of it!
It's now boxed back up for 12-25-2023...
I've wanted a Lion master Challenger for (20) years, and the best part is it's the # 672 From The Clinchfield. ( We only live about 45 Minutes from the Kingsport sub of the old C.C&O.
