SINGAPORE – Train service on the Punggol LRT Line resumed at 8.10am on Sept 13, about three hours after a systems fault led to a disruption.
Free regular and bridging bus services have also ceased, train operator SBS Transit said in a social media post on X at about 8.18am.
Preliminary findings indicate that the fault arose from a premature failure in the new signalling control system which manages train movements, SBS Transit group chief executive Jeffrey Sim said in a statement on Facebook at about 9.10am.
“When the system is down, trains are unable to operate,” he said, adding that trains could not be launched from the depot at the start of operations.
He said SBS Transit is working with the equipment manufacturer to investigate the matter and prevent a recurrence.
He also apologised to affected commuters for the inconvenience.
SBS Transit had announced that service on the Punggol LRT Line was not available due to a systems fault at 5.14am.
In an update at 6.08am, it added that free regular and bridging bus services were available at the Punggol Bus Interchange and designated stops near affected stations.
It had also advised commuters to follow directional signs to get to these boarding points, and to log on to the SBS Transit mobile app, or the LTA MyTransport mobile app, to view alternative transport options.
Its passenger service teams were also on site to assist commuters.
This is the third disruption to the Punggol LRT service in just over a month.
