Eighty people were stuck for an hour at Alton Towers after two monorail trains broke down on the hottest day of the year.
The park’s Air rollercoaster was also temporarily stopped on Wednesday afternoon, with some people stranded in mid-air for 20 minutes.
Alton Towers has now apologised and said the affected monorail train had been removed pending inquiries.
A spokesman said rides and attractions were performing as they should.
“Of course we are very sorry for any inconvenience caused to our guests, and we have apologised to them, but as I’m sure you can appreciate we will not operate a ride if there is any suggestion of a safety compromise,” she said.
