Well, it's all systems go with the 3' 3" wide fiddle yard/Engine Shed board. The cardboard model goes in the boot - just!

The section at the front is the scenic area, I've boxed it in as I intend to make a transport cover for the real thing. The rear fiddle yard lies towards the rear of the boot. It's quite a faff to get it in but it does go.

It struck me as I took the photo how many layout builders go to these lengths to ensure their creations fit their transport, or more to the point design them to within a few mm of NOT fitting? The long sector plate board on Summat Colliery just fits behind the back seats and is longer than the 4' boards that it joins to - all to squeeze that extra length of available track in.

So, next step is to recycle the mock-up (although there are those on here that would consider it a robust baseboard for a "moving diorama" ) and then get some 19mm ply I have reserved at work home for the circular saw to play with.

Must order some more rail from Marcway too!
