King's Cross Railway station is a major London railway that was opened in 1852. King's Cross is featured in the Harry Potter series by J.K. Rowling. The Hogwarts Express uses a secret platform, 9 3/4, to transport students to Hogwarts. King's Cross has since placed a cast iron 9 3/4 sign on the wall against where the movie was filmed with part of a luggage trolley under the sign.
Visit Platform 9¾. Also for Potter fans is this film location at Kings Cross Station, where young witches and wizards must go to board their train to Hogwarts. Platform 9¾ – which is complete with a stuck-in-the-wall luggage cart – is not actually located between platforms 9 and 10, but off to one side of the station
