The Platform 9¾ sign occasionally causes congestion as tourists and Harry Potter fans stop to photograph it or try to push the rest of the luggage trolley through the wall.
King's Cross features in the Harry Potter books, by J. K. Rowling, as the starting point of the Hogwarts Express. The train uses a secret platform 9¾ located by passing through the barrier between platforms 9 and 10.
Unfortunately, platforms 9 and 10 are in a separate building from the main station; also, rather than being adjacent so that a barrier could be between them, they are separated by two intervening tracks. Rowling intended the location to be in the main part of the station, but misremembered the platform numbering. During an interview in 2001, she indicated that she had confused King's Cross with Euston. In fact platforms 9 and 10 at Euston are also separated by two intervening tracks, so either she had yet another station in mind or else she simply did not consider or did not remember the physical arrangement of consecutively numbered platforms there.
... or maybe she's a stupid cow?
