I had a massive train layout 24 years ago. It was about twenty four feet by Fifteen feet. Had well over 100 feet of track, over 100 cars built from kits, and about 15 engines.b I built mountains and tunnels using plaster and paper towel over a chicken wire frame. It was my stress reliever., I really liked working on It.
I loved it. The set belonged to my brother, and I coveted it :)
