Laurie Green was the winner of the LAYOUT IN A CASE competition with his marvellous 1:35n2 scale model of the Arizona Gravel Company. The layout came complete with switching cards and offered a fully operable switching layout - all of which cna be packed away into an airline carry-on case. The 16.5mm track with the 1:35 scale equates to 577mm, a little less than 23", and certainly close enough to two-foot for me.
