Hello Simon,
From Stoke, ahh well can't all be perfect I guess......I'm only joking.
I've been watch a series about railfrieght movements called "rail freight today" it's a dvd box set, from Amazon.
I think you'd find it useful especially the disk about the midlands movements, that said the whole series is pretty interesting as its set in about the same time period your modelling give a year or two. I recommend it fully, but I have to say it's a bit heart breaking to watch and listen too with the dialog, it's so optimistic at times as its pre channel tunnel and preprivatization, but you know what's coming and the out come. It's like the Titanic story, you know the ending but still wish for a different ending all the same.
I appreciate the offer to come down, if you do set up another meet up I'd be up for that, just let me know.
I met Neil the other day, great guy and great layout, if your ever that way pop in, you'll love it.
I wish you the best of luck with being a counsillor, I hope you get to make a difference.
Dave.
