X-Sector includes three rides, The Smiler, Oblivion and Enterprise. Sonic Spinball will also be closed until new safety protocols have been applied.
A prohibition notice has been served on The Smiler by Health and Safety Executive (HSE) inspectors, stopping its use "until action is taken to deal with the cause of the failure".
SAW - The Ride, another multi-car roller coaster manufactured by Gerstlauer which is at Thorpe Park, has also been shut "for the foreseeable future".
Dragon's Fury and Rattlesnake at Chessington World of Adventures are closed because the staff working on them require further training due to the new safety protocols, which have been introduced as an extra measure to reinforce their safe operation.
