People of a certain age grew up dreaming of riding the Hogwarts Express. Departing from Platform 9 3/4 from King's Cross railway station in London it transports carriage-loads of excited students to the Hogwarts School of Witchcraft and Wizardry. It sounded pretty awesome in the books, and Christopher Columbus brought it to life beautifully in 2001's Harry Potter and the Philosopher's Stone (or, if you really insist, Sorcerer's Stone).
