The Big Dipper, 1972
On May 30, 1972, a train was being hoisted to the Big Dipper at Battersea Park. Suddenly, the ride’s start broke which caused the train to roll back. Then the rollback brakes malfunctioned, so the train kept speeding backwards until the carriage in the rear derailed and crashed against a barrier and ultimately crashed on top of two other carriages. There were 13 injuries that day as well as two teen boys and an 8-year-old girl who died on the scene. Two other kids passed away later on from their injuries.
