The £5m fine handed to Alton Towers operator Merlin over last year's Smiler rollercoaster crash is believed to be a record for the industry, a solicitor acting on behalf of eight of the victims has said.
Paul Paxton said the end of the two-day sentencing hearing marks the "closure" of a "long and painful chapter" for the victims, two of whom required leg amputations.
Despite the fine, for what the judge described as an "easily avoidable accident", Mr Paxton added that "money alone will never replace limbs nor heal the psychological scars".
Speaking outside Stafford Crown Court, he said: "It's worth remembering that this hearing is the first time that my clients have heard the full extent of the criticisms against Merlin.
"To be candid, they have been shocked and disappointed by the catalogue of errors. The list goes on and on: a catastrophic failure to assess risk, inadequate training, inadequate supervision, inadequate management, failure to communicate (and a) failure to put in place safe systems of work."
A video showing the moment a carriage on the Smiler rollercoaster at Alton Towers crashed into an empty car has been shown in court.
Merlin, the operator of the park, has been told it should expect a "very large fine" for breaching health and safety.
