Thanks Dave. I found the traveling car threads. What I'm looking for is the thread that shows everyones own cars. There was a link to a numbering system, ie box cars and cabooses and such. Wish I had saved that link.
I missed the last couple, I still have to include those. I'm in the process of moving over to a brand new domain as well, but this page will remain accessible for a while yet (and will be ported over, it'll just be a different URL).
