Swedish accident investigators have determined that the tragic derailment of a roller coaster at Grona Lund park in Stockholm last year, which resulted in the death of one passenger and injuries to nine others, was caused by deficiencies in the ordering, manufacturing, and testing of new support arms for the Jetline trains. The investigation revealed that the support arms were not sufficiently strong, leading to the derailment on June 25.
The roller coaster, which was carrying 11 passengers at the time, experienced a catastrophic failure as the front of the train jumped off the tracks, causing one car to tilt toward the ground. A woman in her 30s was thrown from the ride and tragically lost her life. Two other passengers fell from the train, with one sustaining serious injuries and the other minor injuries. Additionally, seven other passengers suffered minor injuries in the incident.
