SINGAPORE - The Sengkang-Punggol LRT (SPLRT) system is back to full service on the morning of Aug 13, said SBS Transit.

In a post on its X platform at about 5.30am , the transport operator apologised for the inconvenience caused on Aug 12 , when SPLRT services were disrupted for about 10 hours.

Slightly after 11am on Aug 12, train service along an 11-station stretch, between Farrer Park and Punggol Coast , on the North East MRT line (NEL) and the entire SPLRT were crippled by a power fault.

Sengkang LRT services were restored at 3.34pm, and Punggol LRT services at 4.04 pm , with each operating on a single track for the peak period that evening, until services were fully reinstated at 9.20pm , said SBS Transit in a Facebook post on Aug 12 .

In a statement on Aug 12 , SBS Transit group chief executive Jeffrey Sim said the disruption was caused by a failure of the power switchboard at the NEL depot’s substation. This led to a flashover - an unintended electrical discharge - in a voltage transformer used to regulate the power supply.

“This resulted in a trip in both the main and backup power supply as part of the power protection mechanism,” he added.

Power was drawn from SBS Transit’s other substation at Dhoby Ghaut as the faulty voltage transformer at the NEL depot substation could not be repaired immediately after the power trip.

Train services along the NEL were progressively restarted at affected stations before fully resuming across all station from 2.10pm .
