Big Dipper remains closed at Blackpool Pleasure Beach

The Big Dipper rollercoaster remains closed at Blackpool Pleasure Beach while refurbishments are carried out following the recent accident on the ride.

The UK Health and Safety Executive (HSE) are investigating the incident, which occurred on August 11. Blackpool Pleasure Beach are understood to have begun refurbishment work on the Big Dipper, but will have to satify the HSE that additional safety measures are in place to prevent a repeat.

The accident occurred when two trains collided after the first train came to a stop on one of the coaster's hills. 21 passengers were taken to hospital, most with minor injuries, and firefighters scaled 20ft to free the trapped guests. The family of two children involved in the crash has since pledged to sue the park.

The cause of the crash is yet to be announced. A spokesman for HSE said on August 20: "Investigations are still going on at the site, the cause has not been established yet. A prohibition notice has been put on the ride, which mean it cannot start to operate again until repairs have been carried out and the HSE is satisfied with those."
