Darn Joe,
You are about 4 years to late. I knew a guy here that had one of the largest and best model train lay outs in the country and he would help anyone with anything. Several of the model magazines came and took pictures and did big layouts on his. He had all the canyons around here perfect and his tracks ran from in his basement around the walls, out under the patio, he had plugs in the concrete every few feet so he could get to the tracks if something happened, and back through modes of Dunsmuir, Mt. Shasta, and so on. I believe in all he had almost 2 1/2 mile of track and several trains that were computer controlled so if one was coming another would be switched to a side track. Bill passed away from cancer just over 4 years ago and his wife sold the whole layout to some guy from out of state that had came out to one of the meets. He had steam engines that actually ran on steam and did a lot of the work himself.
