The ride is held together by 12 thousand bolts and has a rigorous maintenance schedule.
When operational it travels at a maximum speed of 53mph and has 14 loops.
The rollercoaster closed after an accident, the worst in the park's history, which seriously injured five people.
Alton Towers has apologised after it took up to an hour to evacuate passengers from a broken down monorail on the hottest day of the year.
