Elephant and Castle tube station used to get done every Christmas. They would get into the sidings ,go through the trains stabled there and then walk up the tracks.
Christmas eve used to be the only night where the stations and depots were actually locked up and everyone home.
There are loads of places on the network that use a basic tool/key to gain access.
They did employ security supposedly!
