Four rollercoasters shut after Alton Towers crash

Alton Towers park is expected to reopen 'in the next few days' following Tuesday's accident, a statement from owners Merlin Entertainments said.

However four rides across three of the company's parks will remain closed after new safety protocols were issued.

Here are the details of the rides that have been halted and what to do if you have tickets for Alton Towers.

The Smiler ride sparked the recent park closure and new safety protocols after a crash on Tuesday left 16 people injured, four seriously.

The Smiler opened in May 2013. The ride reaches a top speed of 85mph and height of 30 metres.

Merlin Entertainments have not confirmed how the Dragon's Fury ride is related to The Smiler and what the new safety protocols are.

However since the company adopted them, Dragon's Fury will remain closed for the foreseeable future.

The Rattlesnike ride has been closed for the foreseeable future.

Merlin Entertainment said the ride's operating systems make it difficult to bring in the new safety protocols, resulting its closure.
