Hogwarts Express

The Hogwarts Express was a red train that brought witches and wizards from King's Cross Station in London (platform 9 3/4) to Hogwarts School of Witchcraft and Wizardry. King Peter reveals that the train is passing through a portal up on the border of Scotland, leading from Earth to the Magic Realm (in times of crisis, as in the time of Sauron's resurrection, it actually passes through several in order to fool the enemy). Not many of the students at Hogwarts knew about this until Freedom arrived.

Freedom uses the train for the first time when she comes back to Earth in Resurrection of Sauron; Lone Traveller, travelling to Hogwarts together with Remus Lupin, who is teaching Defense Against the Dark Arts there. She mentions that Mandy used the train every year, with the exception of their first one, but that she herself never used it due to that she spent the summers in Narnia.
