Around 150 MTR passengers were stranded for nearly an hour, with no lighting and air-conditioning, amid a service disruption on the South Island Line on Wednesday morning, Ming Pao Daily reports.
An MTR Corporation spokesperson said the train stopped at 7:25 a.m. inside a tunnel between Admiralty and Ocean Park stations.
Train frequencies between Admiralty and Wong Chuk Hang stations lengthened to every 15 minutes, and between Wong Chuk Hang and South Horizons stations to every six minutes.
The train was later pulled back to Admiralty station for inspection, while another train was dispatched to transfer the affected passengers. Normal train services resumed at 8:20 a.m.
The rail operator was still investigating the cause of the incident.
A female passenger surnamed Cheung said there was a sudden blackout about two minutes after the train departed Admiralty station, and the air-conditioning was also gone.
Some passengers used the torch function of their smartphones, while others opened the emergency windows for ventilation.
One female passenger had to be taken to hospital after she reported feeling unwell.
Under a “performance pledge” mechanism, the train operator could be fined HK$1 million for a service delay of 31 to 60 minutes, with the proceeds used as ticket fare subsidies.
The seven-kilometer South Island Line opened on Dec. 28 last year, serving five stations in the Southern District.
The entire route takes about 11 minutes to complete, with a frequency of every three minutes during peak hours.
