Passengers were detrained at Kranji, and at least one train station was shuttered with commuters being turned away, around lunchtime on Saturday.
This was due to a massive train service disruption on the North South Line. According to transport operator SMRT, normal service resumed at about 2:10pm.
Tweets from SMRT said a "traction power loss between Kranji and Yew Tee" at 12:30pm disrupted train service from Woodlands to Choa Chu Kang stations.
Eyewitnesses who spoke to Yahoo Singapore said commuters were being told to exit stations at both Kranji and Yew Tee, and another reader who visited Marsiling train station at 1:30pm found it completely shuttered, with a banner indicating a disruption in train service.
