Conrail era... but why not have all hands and rifles on deck?
I've got four NIB Atlas engines: Conrail and BN, and two Kato that look lightly used, still in box, engines (GN F units A and B). Those I want good money for. I don't mind dropping a $20 or two on each engine,
Same with Track. It's mostly NIB. A few sticks that were caulked down, but very few. It's just a matter of finding the right price to move it.
The used rolling stock, and still in box building kits, those I expect to take a loss on. Or, I'll donate some to raffle prizes at the next train show.
