South Horizons MTR station on the recently opened South Island Line was temporarily closed on Tuesday night after a burst water pipe caused it to flood.
Regular service resumed around 12.25am on Wednesday after the reopening of the station.
The flooding had prompted service on the South Island Line to terminate at Lei Tung station, with lower train frequencies.
Pictures circulated online by passengers showed ankle-deep water flooding the lobby and water raining down from the ceiling.
An MTR spokesman said water had leaked from the ceiling near exit B at South Horizons at about 8.45pm.
The station’s closure prompted the MTR to arrange alternative buses from Lei Tung station for passengers heading towards the South Horizons area – the last stop on the new South Island Line, which commenced services on December 28.
South Horizons resident Nick Tse said he went to catch the train from Wong Chuk Hang to the end of the line at about 9.50pm, but he was not alerted to the closure until he boarded the train.
He said he an announcement at Lei Tung station informed passengers of the alternative shuttle bus.
“There were not many people waiting for the buses. Only about 20 people on the one I took,” Tse said.
The Water Supplies Department said the private fresh water pipe which provides water to parts of South Horizons estate had been shut down by its workers.
In the meantime, two water trucks and eight tanks were sent to the affected areas.
