Hi Paul,
Love the layout and the detail you have put into it it looks fantastic.
I'm just starting a layout for my two children (boy & girl both 5) and have been looking for an interesting track design and am very interested in emulating parts of yours.
I'm limited to an 8x4 board but would love to fit in a turn table which I have from my old layout when I was younger so i'm going to have to spend a few more hours playing with layouts on scarm to figure out whats possible.
Really enjoyed reading through everything you have been doing and bookmarked loads of it as there are some really great tips in there.
Lee
