The faraway towns.
"They were boarding the Hogwarts Express; talking and laughing as the countryside became greener and tidier;
eating Bertie Bott's Every-Flavour Beans as they sped past Muggle towns;
pulling off their wizard robes and putting on jackets and coats;
pulling into platform nine and three-quarters at King's Cross Station."
- Harry Potter and the Philosopher's Stone (1997)
