Any one know of any 3 rail clubs in or around the Twin Cities area?
The only club that I’m aware of is in Newport, MN (Newport Model RR Club). I do not know if they are 3-rail only, but they do host the events at Woodbury H.S.
What is the one at Bandana Square? Is that an O-guage setup and is there membership availability?
You’re right jlrocks. I forgot about one of the nicest layouts I’ve seen. The Twin Cities Model Railroad Museum. That is an O gauge layout and membership is available. Here is a link.
