There's 2 out of 3 Layouts I know of that were cataloged in CTT. The first Layout is located in Shartlesville PA named Roadside America. There 3 Rail layout is a 100' x 50'. I don't remember what Episode it was in, in CTT. The second Layout is the Detroit Model Railroad Club in Holly, Michigan. I don't know the dimensions, but all I know is it's close to a 100 foot long. It's 2 rail. The third and final layout I know of was not Cataloged in CTT and if it was, it was a long time ago. The layout is named Chi Town Union Station in Commerce Twp, Michigan. The layout is 150' x 75' and it's also 2 Rail.
