crazy idea Crazy idea ?

Hello,
I'm planning to build this layout for absolutely no serious reason except the fun (maybe it's a very serious reason, isn't it?). I found the track plan in a very old French model railway magazine (February 1980). Even if you don't read French, the photos explain everything very well. All your comments, advice and criticisms will be greatly appreciated.

My own track plan. A bridge is included but not shown in the picture.
