This is my first attempt at a permanent layout and after 11 years, its done. I am going to have small groups come in to play trains.
It is 68' x 28', and I used National Parks as the theme. There are 26 National Parks modeled in along with DisneyWorld, town, missile base, airport, and switch yards. It is Lionel O Gauge with TMCC and ranges from 18" off the floor at the bottom of Grand Canyon and 8.5 feet at the 4 peaks of the Grand Tetons. The scenery is scultamold and structolite over white beaded styrofoam.
Hope you enjoy the pics.
