Photos from the Wizarding World of Harry Potter - Diagon Alley and Hogsmeade's constructions at Universal Orlando Resorts from this past week show that the Hogsmeade Station being built in Islands of Adventure will indeed have the same design as the train station from the film
Harry Potter and the Order of the Phoenix (rather from the set from
Sorcerer's Stone, for instance).
Screencaps from the final scene in the fifth movie show Harry and his fellow Hogwarts students heading to Hogsmeade Station, which can be seen here, compared to the design of the building in Orlando - the two have the same architecture, for anyone who was not sure. Those shots, courtesy of
Orlando United, can be seen here.
The Wizarding World of Harry Potter - Diagon Alley will open sometime in summer 2014. Currently most of Diagon Alley, visible to guests who visit Universal Studios Florida, is a mass network of steel framework, and none of the buildings or attractions are completely discernible yet.
