While pondering what to layout I had sketched an idea in my mind to illustrate a wartime story which involves a small coastal forces based in Wales and a nearby holiday camp (aka TB sanitorium) which had been converted to a small RAF station for advanced flight training, the neat thing being that did not restrict me on what aircraft I could display.

A rough sketch showed me the whole concept just would not work on 8x4 at 00, dropping down to N was not an option, I cannot model at that level, 1/76 is my lowest limit except for large ships.

I was also uncomfortable with so many points being out of reach, access is to the top with a narrow squeeze to the right. Even with a pop out access hatch and lift off points in the tunnels I was asking for grief untangling mangled trains.

So back to the drawing board.
