Still haven’t read any of the Harry Potter books, but back in the day I stood on that King’s Cross platform and caught a train. And somehow I also wound up at that cathedral that doubles as Hogwarts in the movies. Spooky.
Still, if you are a Potter spotter, you can catch the Hogwarts Express in action in a picturesque Scottish glen. Also, Auntie Beeb has an inspiring tale of how the train they used was saved from the scrap heap which opened the door for other locomotives to be restored.
