Ocean Park’s Dragon roller coaster was back in operation on Sunday after a minor glitch caused it to be shut down on Saturday afternoon.
The theme park said its safety system detected an abnormality in the ride’s driving mechanism at 3.49pm on Saturday. According to a spokeswoman, the roller coaster stopped just before reaching the end of the platform.
Ocean Park staff helped the 25 passengers on the ride to safety, and no injuries were reported.
The incident occurred as the city sweltered under a record-breaking heatwave, with a 10-day streak of temperatures reaching at least 33 degrees Celsius. It is the longest run of hot weather in the city for the month of May.
The Dragon, one of Ocean Park’s most popular rides, has two 360-degree rotations on a 842-metre track.
The park said in a statement that passengers, who were seated in open-top cars on the outdoor attraction, did not report any discomfort or illness.

“Roller coasters have many sensors and they can be activated when there are strong winds beyond the normal range,” the spokeswoman said, giving one possible reason for the malfunction.
The government’s Electrical and Mechanical Services Department was notified of the incident.
Retired engineer Lo Kok-keung gave several other possible reasons for the suspension, including signalling errors within the control system or problems with mechanical parts, but added that more information was necessary to determine the cause of the glitch.
The roller coaster encountered similar operation issues in June last year, but riders were not seriously affected.
