I thought that people here might be interested to see these photos of a Northern line extension under the Thames which was sealed off after it was hit by a German bomb and flooded in WW2 and then sealed off.

I picked it up from a blog I subscribe to - it's not really a lead as I don't think it would be possible for anyone to get inside without permission.
