# MTR Corp urged to probe possible human error after Hong Kong Island line shutdown

> Hong Kong's MTR Corp is urged to investigate a recent 1½-hour shutdown of the Island line, suspected to be due to human error linked to maintenance protocol noncompliance. Former lawmaker Gary Zhang emphasized the need for strict adherence to maintenance procedures and staff training. The disruption, caused by items from a maintenance vehicle damaging track equipment, led to service suspension between Sheung Wan and Quarry Bay. Authorities have requested a report within a month, with suggestions to improve maintenance practices and possibly adjust service hours for better maintenance scheduling.

Hong Kong’s rail operator has been urged to investigate whether human error was behind the recent 1½-hour partial shutdown of the Island line and to strengthen staff training to prevent similar incidents in the future. Former lawmaker Gary Zhang Xinyu, also ex-MTR Corporation engineer, said on Thursday that the previous day’s disruption was very likely caused by noncompliance with maintenance protocols. “The coming investigation should focus on whether maintenance protocols were strictly followed,” Zhang, now director of the Smart Transportation Alliance, told a radio show. “Unless they encountered an unprecedented mechanical failure, the chances of human error are nowhere near low.” Train services between Sheung Wan and Quarry Bay stations were suspended shortly after the Island line began operating at 6.07am on Wednesday. They resumed at 7.30am. The MTR said items from a maintenance vehicle and damage to track equipment caused the disruption, describing the incident as “rare”. Authorities demanded the MTR submit a report within a month. Zhang explained that maintenance trains usually had extendable parts that must be folded when travelling through certain sections and it was likely that some of these components were not folded as required, damaging equipment along the track. “By design, \[the damaged signal component\] should not come into contact with any train. But if a part extends from the train, it could hook, drag and damage the component,” he said. He added that even if a mechanical failure were to blame for the incident, human error might also have played a role. “The MTR has a comprehensive train inspection procedure. If they failed to detect it, that would still be a management problem,” he said. Zhang urged the MTR to strengthen staff training if the investigation found that human error caused the incident. Speaking on the same show, Ben Chan Han-pan, chairman of the Legislative Council’s transport panel, said the incident might have been caused by failure to strictly follow maintenance protocols under strict time limits. “The investigation should focus on staff training, maintenance protocols and internal monitoring to prevent similar incidents in the future,” he said. He also suggested that the MTR consider ending services earlier on less busy days to carry out large-scale maintenance and ease the time pressure on its engineering team.
