The next morning is pure chaos, with six children preparing their luggage for the year at Hogwarts. Mr. Weasley has enchanted his Ford Anglia so that it will fit all of them plus their luggage and pets comfortably, and after several returns for forgotten items, they finally arrive at King's Cross in time to catch the Hogwarts Express train at platform nine-and-three-quarters. The Hogwarts students arrive at the platform by walking through the wall between platforms nine and ten, and all of the Weasleys successfully do so. When it is time for Harry and Ron to go through the wall, the wall closes up and refuses to let them through. They miss the train, and in a flash of inspiration, they decide to follow the train in Mr. Weasley's flying Ford Anglia.
