After many riders broke bones, the world’s fastest rollercoaster was shut down.
After several riders damaged bones, a ROLLERCOASTER has been closed indefinitely.
After at least six riders were wounded, Do-Dodonpa in Japan’s Fuji-Q Highland Park has been closed until further notice. Four of them suffered back or neck injuries, most likely as a result of the ride’s high speed, which reaches 110 mph in under two seconds.
The ride is the world’s fastest-accelerating coaster, with G-forces similar to a rocket launch.
Sansei Technologies, the company that designed the ride in 2001, claims there were no reports of fractured bones until December of last year, and that they have no idea what caused the injuries.
During the investigation, Fuji-Q Highland also identified no technical difficulties.
“Rollercoaster designs must all adhere to government-approved regulations, so the fact that there are several identical tragedies is unusual,” said Naoya Miyasato, an architecture professor at Nihon University.
Mr Miyasato believes that the ride’s quick acceleration and the manner riders sit are the most likely causes of injury.
“If a cyclist can’t handle the acceleration, they get hurt, which could be what’s occurring here,” he explained.
“If there were no major issues with the ride itself, it may be the way people were sitting. However, it is the obligation of park staff to examine a person’s seating position if they are sitting incorrectly, such as with space between their backs and their seat.”
Riders on the Do-Dodonpa must lean back against their seat with as little gap between their back and the backrest as possible.
However, one of the injured riders told the Japanese news agency Mainichi Shimbun that she may have been sitting forward during the trip.
