Platform 9¾ is a fictional train platform from the Harry Potter series, created by author J.K. Rowling. It is located at King's Cross Station in London and serves as the departure point for the Hogwarts Express, the train that transports students to Hogwarts School of Witchcraft and Wizardry. To access Platform 9¾, witches and wizards must run directly at the barrier between platforms 9 and 10. This magical barrier allows them to pass through and reach the hidden platform, where the Hogwarts Express awaits. The platform is a symbol of the magical world that exists alongside the ordinary one.
