Platform 9¾ | Warner Bros

The Hogwarts Express locomotive transported hundreds of students from Platform 9¾ to Hogwarts School of Witchcraft and Wizardry. Most of the scenes that take place on Platform 9¾ were actually shot on location at King’s Cross Station in London, however, during Harry Potter and the Deathly Hallows – Part 2, part of the station platform was recreated on a soundstage here at Leavesden, complete with the track and the train. The Hogwarts Express provided the background for the very first shot ever captured for Harry Potter and the Philosopher’s Stone and then, ten years later, for the very last shot of the entire series in Harry Potter and the Deathly Hallows – Part 2. The real locomotive and passenger carriages were used on locations throughout the United Kingdom to create the exterior views of the train while a special interior carriage set (built on the soundstages at Leavesden) was used for all of the scenes that take place inside the train. Visual effects artists replaced the green screen background in the windows with moving backdrops and special effects like hopping Chocolate Frogs and flying Dementors.
