h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I read the entries here with Interest, having spent over 10 years using the underground at all times of day - my job used to take me all over it all day long.
I remember hearing or reading somewhere a story that often, when travelling north on the bakerloo line between regents park and baker street stations you could look into the train window opposite where you would be sitting and see the reflection of yourself and a figure in the next seat. Obviously there would be no one there really.
Another variation of this is that a face would be seen looking in through the window opposite as if caught between the train and tunnel.
I did this journey often and never saw a thing.
Has anyone else headrd of this.

I'm also really interested in finding out if anyone has experienced such sightings, as i'm researching ghost stories on the underground. It would be great if the above writer would get in contact with me at:

or anyone who might have had a sighting.

Many thanks!
