Alton Towers will remain closed for a fourth day as investigations into a crash on the Smiler ride at the theme park continue.
Sixteen people were injured, four seriously, in the crash that happened on Tuesday.
The theme park is expected to be shut over the whole weekend whilst safety checks continue.
Merlin Entertainments, who own the park, said on Friday that alongside Smiler, three other rollercoasters at their theme parks would be shut for safety reasons.
The 'Saw' ride at Thorpe Park, is shut "for the foreseeable future".
Dragon's Fury and Rattlesnake rides at Chessington World of Adventures have also been closed.
A Chessington spokeswoman said its two rides were safe, but staff working on them needed further training before they could be reopened, which she hoped would not take more than a few days.
Merlin Entertainments said it planned to reopen Alton Towers in the next few days.
Accidents on rollercoasters are extremely rare - the chance of being injured whilst on a ride is one in 24 million.
The company say they have added safety procedures to "reinforce the safe operation of our multi-car rollercoasters" which were "effective immediately".
