Hello. It's a bit of a long shot but I'm trying to find a British Rail training, or cab ride video. The reason I am trying to find it is because my Granddad was shown in this training video demonstrating a new cab communication set-up, but true to British Rail the system wasn't up and working at the time so my Granddad had to pretend there was someone at the other end. I remember that the handset looked like the ones you used to see on the phones with the big dials on them I believe this was made in the 70s, and his trains would've been on the Eastleigh line, but not sure if it was to London, Pompey or Brighton. His name was Jim Alexander. I know it's not much to go on but you never know. Thank you.
