I can't believe I would have a chance to see OGR greats George S. and Dennis Holler at Train Town!
I live near Train Town and stop in every Friday afternoon when I drive my daughter to lacrosse practice. It is the only store where I've actually seen prewar tinplate trains. Also, they have 1970's-modern O Gauge, in-the-box, rolling stock priced at $20-30. They appear to be big into buying collections and then (get this) selling the inventory . So I usually walk out of there with at least one O Gauge car. However, while I admire their prewar tinplate, I don't buy any of it. I stick with modern repros. All of my tinplate (and almost all O Gauge for that matter) is from eBay, OGR, train shows, or forum sponsors.
Anyway, regarding Train Town, it's a tiny strip mall storefront but looks can be deceiving. The place is packed with inventory. There are only two narrow aisles leading from the front door to the cash register. That is all postwar/prewar. There is a small back/sideroom that contains all the modern stuff. When I first discovered it (a few weeks ago) I was prepared to be underwhelmed based on the look and size. Now it's the only LHS I go to. It's run by a couple of brothers and a sister. They are very nice, welcoming, and accommodating (another LHS scarcity IMO).
