Well I must say Jonny this one has got me stumped big time . There are lots of clues in the picture that to my mind can only lead to one or two stations, but the stations I am thinking of look nothing like the one in the Picture!
Which leads me to believe the picture may have been edited?
I didn't take the picture myself, but a schoolfriend of mine did on a trip to London. I'm quite sure that he did not edit it, but I will ask him tomorrow. It does look realistic to me.
I'm confident that this is a good likeness of the location listed in my answer - though obviously it's a little harder to identify in the dark. Once I had an idea of which station it was likely to be, everything seemed to fit into place. So I don't think there's any need to invoke editing to explain this picture.
