Train service on the North-South Line towards Marina Bay station was disrupted on Monday morning, at about 7.45 am.

Train operator SMRT said on its official Facebook page that there was a track circuit failure between Jurong East and Kranji stations, and its engineers have been sent to investigate and rectify the fault.

SMRT added that the fault caused the train platforms on Yishun, Sembawang and Khatib stations to be crowded. Free bus services have been activated between Admiralty and Ang Mo Kio stations.

The train operator said on its official Twitter account that travel time from Jurong East to Kranji station is expected to take 10 minutes more, due to the track fault.
