The owners of Alton Towers have been told they face a large fine after admitting safety breaches on the Smiler rollercoaster ride.
Merlin Attractions Operations Ltd indicated a guilty plea to charges of breaching the Health and Safety Act.
District Judge John McGarva, sitting at North Staffordshire Justice Centre, said the incident was a very serious case leading to life-changing injuries.
Two women had leg amputations after last June’s crash.
Mr McGarva warned the firm it “may be ordered to pay a very large fine” when it is sentenced at Stafford Crown Court.
Speaking for the first time about the crash, Chanda Chauhan, who was on the ride, said the aftermath was like “a horror movie”.
