Elephant and Castle hauntings

A ghost story for Halloween When this station is closed people have heard the steps of an invisible runner, strange tappings and doors being thrown open.
What follows is a genuine testimony from an h2g2 Researcher — a tube driver on the London Underground. He’s actually seen the ghost but didn’t appear to be all that impressed
’Twas around six of the evening at a Bakerloo line Underground Station — about a week ago. I was in pursuit of my duties as an employee of London Underground (Northern Line — and I should apologise to all who are condemned to this line — not my fault Really. Heh! Heh!)
So I join the train at the terminus at Elephant and Castle and walk forward to the front of the train with a view to travelling with the driver. At this point the driver has not arrived so I put my bag down and move to the rear door to wait for him. While I am waiting a girl gets into the carraige — she walks straight through the carriage and I have to move aside making some muttered apology — I sort of have to do this since I was in uniform!
A minute or so later the driver turns up, and we move toward the front of the train. I notice that the girl is not in the carriage and this is a rather immediate cause for concern — she could not have left the train without passing me — I had full view of the carraige and platform at the time. My reaction was to inform the driver — the only place she could have gone was to have walked down the tunnel — not really what we want! The driver’s response was unusual: ‘Oh, her. We hear about her all the time — she’s even been in the papers.’
