Water leakage was the cause of platform screen door glitch on May 3

Water leakage was the culprit behind the platform screen door glitch on the Downtown Line (DTL) on May 3, according to a report by Todayonline on May 19, 2017. The train line hit a record seven-hour snarl following the leakage. 

The leakage damaged the electrical components of one of the platform screen doors at the Botanic Gardens MRT Station. It was caused by natural groundwater seeping in from the space above the affected platform screen door. “The seepage has since been grouted by injecting a polyurethane chemical to fill the void, and act as a water stop,” said SBS Transit.

The platform screen doors at the Botanic Gardens station were checkedas part of routine maintenance in September last year. None were found to be faulty then. There was also no water seepage observed. 

Following the incident, all platform screen doors, as well as the electrical wiring and components, at train stations along the DTL and NEL, have been inspected. “Minor water seepage was found at two (platform screen doors) at the King Albert Park station," said SBS Transit. Their electrical components were not affected, however, and the seepage have since been grouted.

SBS Transit is currently working with the Land Transport Authority on the water seepage issue.
