Which London railway station has a platform sign marking the Harry Potter Platform 9¾?

King’s Cross Station has a platform sign marking the fictional Harry Potter Platform 9¾. The sign and a luggage trolley installation became a well-known visitor attraction at the London station.

In the novels, the Hogwarts Express leaves from Platform 9¾, a magical platform located between ordinary platforms 9 and 10. King’s Cross is therefore the departure point for students traveling to Hogwarts, even though the platform does not exist as a normal railway platform.

The attraction was originally placed near the platforms and later moved within the station during redevelopment. A Harry Potter shop stands nearby, reinforcing the location’s connection with the series.

King’s Cross is sometimes confused with St Pancras because the two major stations stand next to each other. The books specifically use King’s Cross, while St Pancras provides the distinctive neighboring exterior often seen in photographs of the area.
