1'X6' N scale ABL switching layout from MRP2005

I described this folding layout in my article in Model Railroad Planning 2005. It's based on the Alameda Belt Line, a terminal switching railroad on Alameda Island (northern CA bay area). The ABL was once jointly owned by the Santa Fe and Western Pacific, but is now defunct, sadly. Read more about this shelf switching track plan here: http://www.layoutvision.com/gallery/id32.html
