Alton Towers remains closed for a third day, racking up losses of millions of pounds as health and safety inspectors comb the site for clues to what caused the rollercoaster crash.
Sixteen people were injured, four seriously, when two carriages on the Smiler ride collided.
The resort has been shut to the public since the "major incident" at around 2pm on Tuesday, with the Health and Safety Executive (HSE) on site.
The owner of the theme parked is believed to have lost just under £1.5m in the three days since the collision.
Neil Craig, head of operations for HSE in the Midlands, said that a specialist team of inspectors were at the scene in Staffordshire making inquiries.
