Not sure if this has been posted before - it is OO gauge
Youtube recommended this vid (https://www.youtube.com/watch?v=x24nyGcf2sc) to me
Then found the blog (http://dougattrenholmebar.blogspot.co.uk/) that lists the kit used and more details about the filming and there are other blog entries about the layout
And this is the YouTube channel (http://dougattrenholmebar.blogspot.co.uk/) with some more amazing videos including DMU passenger views.
I could spend months watching these videos :goggleeyes:
Yeah I watched that some time ago. It's a big layout!
