Walibi Holland is a large dutch amusement park with over 40 attractions. One of these attractions was the rollercoaster La Via Volta. La Via Volta is a so-called Boomerang rollercoaster. In 2007, Walibi decided to close La Via Volta.
However, La Via Volta was closed, the rollercoaster with the original blue, orange and yellow colours stayed unused in the park for over 3 years until Walibi decided to revive the ride.
In 2010, Vicom4® Outdoor helped Walibi reviving the rollercoaster by turning the original colours into purple and orange. After the refurbishment was completed, the rollercoaster, now called the Speed of Sound, is up and running again.
