There are quite a lot of imaginative touches at Universal Studios Harry Potter theme parks. One of them is the Hogwarts train that takes you from Diagon Alley at the Universal Studios park over to Hogsmeade and the Islands of Adventure Park and back again.
The train station, the train and the individual cars that you sit in, are all very much from the movie.
While it gets you from one park to another, it is also a ride in and of itself. On one side are the windows looking out. You get to watch London segue to the countryside and ominous dark clouds appearing and then suddenly Hogwarts is in the distance and you’re at the train station with Hagrid waving at you. It’s a little mini movie.
But wait there’s more. In the hallway is also some action going on you see silhouettes of our heroes talking and then a death eater hand appears against the glass, Harry casts a spell and before you know it a silhouette of the trolley cart shows up.
You have to ride the train a lot to really get an appreciation of everything that’s going on.
There’s still more, the return trip from Hogsmeade to Diagon Alley has different indoor and outdoor scenes.
This link to YouTube shows it in detail if you want to be spoiled.
