Shocked & Disappointed (Harry Potter Hogwarts Express)

Maybe Mister No, but I'd more likely scratchbuild my own version inspired by it; albeit in a brighter shade of red (perhaps metallic), loco-drive and with non-opening coaches.

Getting a realistic looking train would involve buying four sets so as to get the four coaches required, which would be ridiculously expensive. However, although Spencer's coaches are not quite the right model, I do think they might look OK. It depends on how close the colour turns out to be.

The real King's Cross station has a sign for the fictional platform on the wall between platforms 9 and 10, as well as the rear end of a "disappearing" trolley for photo opportunities.
