Train service on the North-South Line was disrupted between four MRT stations on the morning of 16 December 2019, after a signalling fault hit the line.
In a post on Twitter at about 8.15am, rail operator SMRT announced that there were no train services between Kranji and Bukit Gombak MRT stations as a result of the fault. It added that free regular bus and bridging bus services have been made available between Kranji and Jurong East stations.
Some commuters said on social media that the fault started at around 8:00am. Some were on the trains when the signalling fault occurred. Pictures posted online after the fault occurred appeared to show large crowds waiting for the bus at Choa Chu Kang bus interchange. The operator said in an update at about 8.50am that the fault was rectified and that train services were progressively returning to normal.
