Actually from my last comment I realise I do have a rail-related DVD which gets regular viewing. Which may also help those researching various projects...
The video I'm talking about is one about the Fell that's listed on the BFI website, contact with the BFI and then the Shell Film Centre (yes really!) got me a copy of this otherwise unreleased DVD. So, if you see films listed that aren't on general release it's still worth tracking them down, you might be surprised how easy they can be to get hold of for personal use. I know I was!
