There have been lots & lots of rumours about things on the underground
i.e. tube station for Buckingham Palace being one such. There are a
number on several threads just so we can put them all on one thread so
feel free to put what you have heard or know about. My own is that
there is supposed to be a siding at St Jame's Park, which there is not
there was a crossover taken out in the 1960s but further there's
supposed to be a train stabled there for use in an emergency.
