The owners of Alton Towers have been fined £5million with costs of £69,955.40 following a rollercoaster collision which left 16 people injured, a number of them seriously.

Two young women on the Smiler ride suffered leg amputations and others suffered severe injuries when their carriage collided with a stationary carriage on the same track on 2 June 2015.

Stafford Crown Court heard that on the day of the incident engineers overrode the Smiler’s control system without the knowledge and understanding to ensure it was safe to do so.

A Health and Safety Executive (HSE) investigation found no fault with the track, the cars, or the control system that keeps the cars apart from each other when the ride is running.

Investigators found the root cause to be a lack of detailed, robust arrangements for making safety critical decisions. The whole system, from training through to fixing faults, was not strong enough to stop a series of errors by staff when working with people on the ride.

Following the incident Alton Towers made technical improvements to the ride and changed their systems.

Merlin Attractions Operation Ltd of 3 Market Close, Poole, Dorset pleaded guilty to breaching section 3(1) of the Health and Safety at Work Act etc, 1974 and were fined £5million with costs of £69,955.40.
