Hm. I have not hear of any connectivity issues in years.

I suggest reaching out to Ring Engineering to troubleshoot it with them.
A phone call can go a long way with this sort of thing.

Let us know how you make out!

i agree that the ebay fee is high!

if it were me, and you have a well-attended train show in your area, that would be my choice.

Don't even mention rolling stock, I told my wife not to put dirt on top of the casket, just have everybody throw a tub of rolling stock in the hole - 

In an effort to get organized, I recently rearranged the shelves in the basement, thinned out other hoarding things like Xmas decorations, Halloween decorations, useless boating accessories (I had a boat problem also over last 25 years) - then back into trains.

I un-tubbed all the locos and stacked on 1 shelf, this way I have easy access to sort them out - what stays, what gets RP, what can I live without ...
then I need to un-tub the rolling stock - same thing on another shelf. The shelves are 2' wide x 8' long.
I also organized all the "projects" (loco's needing work, paint, decals, RP, etc) with individual/labeled Tupperware containers.

This method gives you big picture all at once - out in the open, instead of 10 Walmart tubs full of trains. You get the picture.

Selling process ? What do you guys see as best method of selling old stuff ?
Ebay? - seems they want like 15%
FB Marketplace? - I sold other stuff thru that, bit of a hassle - but does sell.
Local Trainshows ?
Call wholesaler and dump for pennies on the dollar?

I too had a problem with getting more engines than I could run..  Now I have somewhere around 12 runners but while my affliction was  buying engines, I bought a lot of RP items for them and I suppose I should thin those out also as I decided not to get any motive power but hold that option open as in case ?  I can have too much ?  At least that is how my wife feels. What do I need with 50 boxes of Cache Creek HO freight cars? And the road goes on forever..   Don't ask me about peddling all of my Lionel accessories.  I had that monkey on my back too !  Your version might be different and true.  What is that for sale over there ?

The best answer is TEST your wiring...  with 4 wire trucks, it's easy to apply power until you see the motors turning... then you know the 2 wires... also you can determine which lead is "positive" so you sync the truck direction.

You can use a multimeter to double check the other 2 wires are track pickups.

NEVER trust the wire colors completely (although LGB rarely makes mistakes)... Aristo and Bachmann are often guilty of inconsistent wiring.
