Below is a quote from Dennis in an earlier post and I forgot to respond to it.
"Besides building models he's thinking of his model as he would a real railroad albeit with some compromises of course. "
You are quite right Dennis for me Barchester really lives, it has a life of it's own and is in fact Barchester Mk II. The first Barchester was in my loft in the UK and had to stay behind when the house was sold when we moved to Spain, less rolling stock, which is a story on it's own, and this Barchester takes over where the other one left off. The only difference in layout is the length, MkII being much shorter, but the history carries on from the first layout. Whatever happens on Barchester has to be accounted for in real life, costings, planning permission, commercial interests etc. Everything has a valid reason for what it does. All this probably sounds daft and way over the top to most people but I took my initial inspiration from Peter Denny's Buckingham Branch line and have never looked back.
