I have a copy of the Lionel track plan for this layout and have never seen one built up. I was wondering if anyone else had? It's dated March 1959. I was rather surprised at the complexity and number of operating accessories for a "lowly O27" layout!
It looks like a LOT of action in a 5 x 9 space but uses the crappy 1122 switches (6 of 'em.) I already have a 4 x 24 O27 layout with many 1122's on it and you absolutely cannot back up thru the curved part of them without a derail. (Sometimes even going forward thru the curve ends up in a derail!)
Maybe I should look at re-doing this in O31 "O" trackage. It might be a fun project to involve the grandkids...
