The “Blå Tåget” ride already existed but has gone through a total makeover. This ride is a ghost train loaded with new chills, thrills and effects especially designed for visitors’ enjoyment. The train passes through several chambers, each filled with skeletons, scarecrows, rats, wolves, fire, lightnings, ghosts and more!

The setting inside the ride was designed by artist Magnus Sörman and the entrance to the ride was designed by artist Joakim Hansén. For the technical making of this nerve tickling and scary adventure-ride, Kreativ Teknik was contacted by Gröna Lund. Kreativ Teknik, a Swedish-based company which mainly works with lighting, control systems and effects, selected Medialon to be part of the project.

Kreativ Teknik delivered a total solution including lighting, smoke, video projectors, control system, as well as the programming of the entire ride’s special effects.

One Medialon Showmaster Pro embedded show controller controls and synchronizes the entire AV system. Medialon controls everything from light and sound to lightnings, smoke-effects, movements of the animatronics and video which are continuously timed and trigged by the exact positions of the train’s chariots.

Medialon Showmaster Pro controls the following equipment:
23x Advantech ADAM I/O Interface, to control the animatronics via pneumatics
1x Sandbox Ether DMX Interface
2x Brightsign Network Video players
2x Projectors
1x Fog screen
1x Smoke machine
1x Strobe
4x Tesla coil flash-generators
1x Gas-flame
112x LED-fixtures of different models and brands
3x dimmers
21x ID-AL Mp3-players

“It was surprisingly quick and easy to set the timings of the animatronics together with the effects. I really liked the system and I want to continue to work with it in my future projects” says Marcus Persson, Project Manager and CEO at Kreativ Teknik.

“We think that the project has been carried out really well and it’s been done with great interest and commitment!”, declares Peter Osbeck, Ride Manager at Gröna Lund.

“This is a huge project we are very proud of!”, concludes Marcus Persson.
