Randy has been building model train layouts for the last 6 years. The current layout is built in the attic of our house and is approximately 14 feet by 19 feet in size. In N-Scale this translates into a lot of track! There are over 75 turnouts and several hundred feet of track on the layout. The scenery is still in progress, but the trackwork is in place. There are about a dozen bridges and a six turn helix included on the layout.
