Next time you're there, take the lift. If you go in from the
platforms, face the opposite way, if you go in from the ticket hall,
turn round and face the doors you came in through.

Half way through the lift journey, you'll see the passage. Then maybe
you might have an idea what it might be for, or where it goes, or why
its tiled like a public passage.
