In the Harry Potter stories, which platform does the Hogwarts Express leave from at London’s King’s Cross station?

The story behind the answer

In the Harry Potter stories, the Hogwarts Express leaves from Platform Nine and Three-Quarters at London’s King’s Cross station.

The hidden platform is reached by passing through a barrier between Platforms 9 and 10. It is the departure point for students traveling to Hogwarts at the beginning of the school year, making it one of the series’ best-known back-to-school locations.

The platform is fictional, but King’s Cross station has embraced the association. A Platform 9¾ sign and luggage trolley installation became a popular visitor attraction, and a themed shop operates nearby.

The real station’s Platforms 9 and 10 are not arranged exactly as described in the books. Film production also used nearby St Pancras and a redesigned setting to create the magical railway scenes.
