Palallin, Where did you get your mine carts? I have the Lionel mine kit and I am going to add track to it and put some carts on it but I can't find them.
Mike, I got them both off eBay. One was part of a somewhat non-politically correct set of miners--mostly pan but some obviously for bigger operations--and mules that I had to assemble and paint. The other was a kit that I got from a well-known seller, but I am afraid I can't think of the names of either of them right now. Sorry! Try searching O Scale under Model RRs for "miners" or "mines." That's what I did, but it was a few years ago.
