The Hogwarts Express runs between London, Kings Cross Station Platform 9 3⁄4 and Hogsmeade Station in the Harry Potter movie franchise. The Express dutifully carries students to and from Hogwarts School of Witchcraft and Wizardry at the start and end of every term. Originally steam fitted by the Muggles (non-magic people) who built it, the Hogwarts Express now runs exclusively on magic.
