Thirteen (sometimes written as TH13TEEN) is a steel family roller coaster at Alton Towers in Alton, Staffordshire, England, United Kingdom. The ride was built by Intamin and was officially opened on the 20th March 2010. The ride is a replacement for Corkscrew, which resided at the park for 28 years between 1980 and 2008.

Early Development[edit | edit source]

The park first revealed their plans for the ride in October 2008 when explaining the reasoning for the removal of the Corkscrew. Planning permission was initially delayed due to concerns about the Iron Age hill fort in the vicinity. However, in March 2009, Staffordshire Moorlands District Council accepted planning permission for the ride (with conditions) and groundwork construction commenced about three months later. During the planning stages and construction, the ride was codenamed 'Scecret Weapon 6', a trend that had been started with 2 planned but unbuilt pre-Nemesis coasters at Alton Towers, and has continued with all the major thrill coasters except Rita ever since.

The initial idea for the secret element originated from a previous roller coaster plan designed by John Wardley, Ride Consultant for Merlin Entertainments, in which a piece of track tilted back and forth during the ride. This, however, would not have been a worlds first though, as a similar concept was put in effect with Vekoma's Gravity Max. Thus the original ride design never came to fruition, however the concept of a moving track piece was kept and developed into the world's first free falling track piece.
