Oooooh! British Railways green! I love it, I would like to get some of the Hornby platforms that you show, they are a little hard to find in the US. I knew I should have picked some uo while in the UK. Nice pictures.
Basementdweller: look at the BRMNA site for their member dealers. There are a couple in southern Ontario that probably have what you want. (Model Railway Imports and The British Connection.)
(I made platforms out of the 1/2" styrofoam.)
