RMweb 2011 challenge: proof of concept

Well, it might be creeping back, the 4mm mojo...

After a few days musing over the RMweb diorama challenge I think I've come up with a model that will be a useful photo plank, small shunting layout and something to get me working in the smaller scales again.
G-scale projects still dot the workbench and I'm going to start on another structure too soon, but this diorama, provisionally titled Paxton Road 2, uses track, ballast and scenic materials I have in stock. I just need to draw up a baseboard design that will allow a small cassette/traverser system to be put alongside.
