Hi, I live just a spit away from all this! In fact only this morning I went over that road bridge in my daughter's car to get to Upwell Post Office to do some photocopying!
I've lived in this area for years. In fact the excellent health centre where they look after me so well is built on the old terminus!
I've just made a master for the 0-4-0 tram loco in 2mm scale for N-Drive, so you could make all this half the size<g>
I once bought a last minute Christmas present in that corner shop, which is now, alas just a house.
I have something planned for 7mm scale for the same sort of area only further up river. Tony Moss's little country garage, so long a part of the scene just a bit further down is the picture on my avatar (albeit a bit squashed by the forum software!). I plan a small layout with a fictional extension of the W&U down past the garage, incorporating his famous "Shack" cafe, beloved of the local racers and bike boys in the late 60s. I have all Tony's old photos to make sure it's a good model.
I'd love to be involved in any way if I may be of use, please PM me.
