SINGAPORE - A signalling fault that occurred between Lorong Chuan and Caldecott on the Circle Line caused delays for commuters during the morning peak hour travel on Friday (May 21).

Alerting commuters about the delay on its Facebook page at 6.36am, SMRT wrote: "Our engineers were immediately deployed and are working to rectify the fault. Trains are moving at a much slower speed."

Delays lasted for an hour.

In a Twitter post at around 7.30am, SMRT wrote: "Train services have resumed. Free regular and bridging bus services have ceased. We are sorry for affecting your morning commute."

During the affected hour, the train operator made announcements in-train and at affected stations to advise commuters to add additional train travel time between Serangoon and Farrer Road.

Commuters were also advised to make alternative travel arrangements including taking other train lines - East-West Line, North-South Line, North-East Line and Downtown Line.

SMRT said that free regular and bridging bus services were available between Paya Lebar and Buona Vista MRT stations.

Some affected commuters, however, could not find the bridging services and made their unhappiness known on social media.
