Ray and John: Thanks, and I planned the whole layout that way from the beginning. I've seen too many guys who had to scrap a good layout in a move.. There are those who haven't done badly in a move, but I don't have the time to spend on trains like I want. I planned the benchwork for the Southeastern Michigan S Gaugers portable display layout, and used the same principles on my home layout. It's basically salvaged lumber from a high school's bleachers which were scrapped. The boards were very dry 1.5" x 12" clear fir. I planed the boards down to 1" and ripped to 4" widths. No warpage at ALL. Each section weighs less than 20#, including the foam terrain. And John, there's NO WAY anybody but me is moving my trains. I plan on renting a storage unit to store everything until we find a new place. Eight sections and 10 plastic tubs plus assorted boxes. I too have heard too many horror stories about "missing" trains when moving. BTW, the trackage in the foreground of the photos is a return path for a streetcar line, which resembles a subway tunnel.
Cal, Good hearing from you again. Contact me off list and we'll catch up! Email is in my profile.
