Hogwarts Express
Harry Potter met his two best friends Ron Weasley and Hermione Granger on his first ride on the Hogwarts Express. So far he has been on the train nine times- twice a year for each of his first five years at Hogwarts except once, in Harry Potter and the Chamber of Secrets when he flew with Ron in a bewitched Muggle car, which crashed on landing and escaped into the woods (The car later saved him from the gigantic spiders in the Forbidden Forest). After each school year, Harry was met by his uncle and aunt after getting off the train; even though they hate him very much, they have never failed to pick him up.
The Hogwarts Express is a steam train only in appearance and somewhat in function. The train is a magical device. It borrows its form and its intended function from real steam trains, but not the technology.
The locomotive used in filming is a Great Western Railway Hall Class Ogden Hall. The film was filmed at Kings Cross railway station and the North Yorkshire Moors Railway
The interior is used for filming.
The 'Harry Potter Train' is ridable regularly at Pickering (the 'hotspot' of the North Yorkshire Moors Railway, but has been part of a large argument between the companies and local train enthusiasts as it is not run in the colour intended for the engine (many train enthusiasts claiming that the purple colour has defiled the once-beautiful engine)
An OO gauge model is produced by Hornby [1], though this is of a Castle Class locomotive rather than a Hall Class.The Real Thing
