The shelter has been moved from it's original position on the other side of the road (see previous pic) and is currently residing here on the pavement by Russell Square. As it doesn't seem to have been permanently removed I'm hoping they're going to put it back and re-open it.
It looks as if it's in the process of being restored. The roof covering was removed a few weeks back (when it was in it's original place) and it looked then as if the roof was being repaired.
