Well, now I'm kinda worried. I haven't regularly ran my trains for 20 yrs. Whats worse is I have several engines that are 20+ yrs old that are still in the box. Nothing will be run again until the move is finished. I know they will need lube maintenance, inspection of foam padding, cracked wires, polish of the e-unit contacts, etc.
Nothing I can do about it now. After the dust settles, I plan to pull them out one at a time and see what happens. Postwar should go pretty easy. The newer stuff will be a crap shoot.
Overall, I would still rather have bought the trains I wanted over the years and deal with the future consequences of them sitting idle.
