There is a guide for people wishing to do some photography on stations can be found on the national rail website.

Generally speaking though, on stations or properties where enthusiasts would not be expected, tell the local manager you are there, and tell them why. I must admit I once asked a Virgin employee at Euston if it was alright for me to go up the platform and he gave me one of those looks, you know the ones.
