I'm surprised no one has mentioned platform 9¾ at Kings Cross

And platform 13 - "The secret of Platform 13" - well before Harry Pothead

Exeter St. Davids also has the problem of London-bound services departing from two different platforms but in opposite directions depending on whether you're headed for Waterloo or Paddington. So, as they say, which way is "Up"?
