Okay, I think this is the final plan (tempting fate I know). I have added a second link to the full size bitmap for anyone who wants a slightly clearer image. I thought it might be too big to post directly... if it isn't I'll attach it here.

I wasn't happy with the central switching area but the latest modifications allow me to run 3 trains continuously and then be able to switch the 2 mainline trains into stations whilst allowing the local loop train to run through a bypass siding to continue running.
It gives me better access to the industries and the roundhouse and after several hours tinkering and playing with it in XTrkCAD running trains, I think I like it. The staging area is smaller than I wanted but I have listened to the advice on here and tried to balance everything out as well as possible. I have given the upper industry a double entry to allow the loco to switch ends and change running direction.
I've put some rough colours in just to show how the feel of the layout runs from soft, rural down the left to hard brick and stone down the right. I think the two distinct textures should give the layout a nice feel and give the trains a varied backdrop to be seen against.
The nice thing is that I am starting to visualise the layout as an environment rather than some track on a board which is going to make the difficult task of adding scenery a bit easier.
Now that I have passed the planning stage, I can start building... I'll post images as I go.
Thanks again to all who have offered insight and advice. As I hope you can see, it hasn't been ignored and I feel my layout has massively improved as a result. :thumb:
