Hogwarts Express placed on tracks at Universal Orlando
Oct 26, 2013

Universal Orlando's expansion to the Wizarding World of Harry Potter doesn't open until next year, but guests can already see progress happening. The expansion will include the Hogwarts Express train to carry passengers back and forth between the two theme parks. This week, the locomotive and train tender was placed onto the tracks. The train will travel from Hogsmeade Village in Islands of Adventure to Diagon Alley in Universal Studios. On its journey, the train will pass through some backstage areas, but guests will see digital projections of the English countryside. See a photo of the train here.
