Hi all, I hope this is permitted in this forum! I'm currently building a small Brio set for my 2 year old's birthday, and I'm infuriating myself by changing track plans every few hours! Many people have said "don't stick it down", but he has a huge box of track as well as this board. I wanted this board to be something a bit more permanent to go alongside the loose, different-every-time spare track. So - I have added a couple of images, and would appreciate any comments as to how to improve either ideas, or even draw up a fresh plan if you're really, really bored. I'm an amateur modeller myself, and I normally go for the "less is more" approach, but this is for a 2-year old. As such, I'd like as many routes/loops/bridges etc. as possible to keep him entertained. I'd also like a small open space (visible in both designs) to add in some small roads and small Brio buildings/trees that I have. Many thanks - and mods: apologies if this is not permitted on this forum.

As with Ring Road, and the layout before that, you have simply got the modern image 'feel' to a tee. How did you find the correct measurements for the green road signs? Would like something similar on my OO layout.
