Down here in southern Missisippi there is no used train market, however when I
attended the Foley, Alabama train show I was quite surprised at how much and how low the prices were for all toy train gauges, esp. O.
I asked around and found that so many folks retire to the south and down size
so they have to sell their collections.
I have purchased on that EBay place and got what I wanted and it worked until
either it or me wore out. Now it's one of those 'Queens' you guys mention from time to time. Nice to look at, and something to dust, but I had my fun and am satisfied.
