Next job is to place the building on the layout next weekend and start looking at ground and platform levels.
The signs are proving more troublesome than I'd hoped and for now I've abandoned the idea of using 1mm brass lettering as I couldn't get a result that I was happy with. I've resorted to producing them on my computer - the ones on the left are early efforts which are passable (though hard to photograph clearly) but I'm much happier with the ones on the right - just got to go back and do the smaller ones again.
