“Harry Potter: The Exhibition has mesmerized audiences worldwide and we are truly excited to bring this immersive experience to Germany,” said Karen McTier, Executive Vice President, Domestic Licensing and Worldwide Marketing, Warner Bros.

Earlier today (technically yesterday) Universal held a press event where they revealed new details about the Diagon Alley expansion of The Wizarding World of Harry Potter in Orlando, Florida.  Some new promotional photos were also released, those may be seen in the gallery.  They still have not announced a set opening day, but still state Summer 2014.

One of the most memorable and exciting experiences from the Harry Potter series will come to life at Universal Orlando Resort this summer. Imagine:

• Being transported from the Muggle world to the wizarding world as you pass through the brick wall at King’s Cross Station to arrive at Platform 9 3?4
• Watching in amazement as the Hogwarts Express pulls into the station – its billowing steam and authentic whistle beckoning you to hop aboard
• Sitting in one of the train’s cabins with your family and friends and actually riding the Hogwarts Express – just as your favorite characters did in the Harry Potter films
• Looking outside your cabin window and enjoying a scenic, breathtaking journey through the British countryside as you encounter magical creatures, some of your favorite Harry Potter characters…and even Dementors…

The Hogwarts Express will connect the new portion in Universal Studios Florida with The Wizarding World of Harry Potter – Hogsmeade in Islands of Adventure – allowing guests with park-to-park admission to enjoy a real journey aboard the iconic locomotive. Details on the train ride are as follows:

The Hogwarts Express experience combines powerful storytelling, live special effects, lifelike animation and state-of-the-art technology to take riders on the journey of a lifetime. Guests will enjoy two completely different experiences depending on whether they’re traveling to Hogsmeade or London.

Once seated in the cabin, guests will be able to look out their windows as an incredibly authentic and magical adventure unfolds before them. They’ll see Hagrid come alongside the train on his flying motorbike, Buckbeak the Hippogriff swoop gracefully over the black lake, the Weasley twins on brooms and up to their usual antics, the Knight Bus swerving through London traffic – and other special moments and surprises.

Universal’s Creative team has been working closely with Warner Bros., Stuart Craig and the production team from the Harry Potter films to create a sensational Hogwarts Express experience that the entire family can enjoy. The Creative team has gone to great lengths to ensure the experience is true to the books and films. Everything about the train is authentic – from the paint and the materials used to build it….all the way down to the whistle.
