I have a great wife: when asked whether I could evict middle child from his bedroom to install giant layout, she said, no, but I could rent a studio in a converted mill nearby if I wanted... Must remember to keep her happy!
I'm not really interested in buying this layout, but wondered what's what with it. Looks sort of strange to me - lots of track, lots of work done, but toyish in layout and hard to operate. Looks like it reflects a style of "let em run" operation rather than realistic operation. Also, as a friend pointed out, why do to that length and install above table switch machines?
