2011 train disruptions

On 15 December 2011, services between Bishan and Marina Bay stations were disrupted due to damage sustained on the power rail between Dhoby Ghaut and City Hall. Trains along the stretch were stalled and caused a service disruption until 11.40pm on that day. Two days later, a similar problem caused a seven-hour disruption between Ang Mo Kio and Marina Bay. According to the Committee of Inquiry (COI) report, both disruption was caused by damage to the third rail and the trains' collector shoes.

2015 train disruption

On 7 July 2015 at about 7.20pm, both the North–South Line and East–West Line were temporarily disrupted due to massive power trips detected along the line. Train service resumed at 10.35pm at a reduced speed. The cause of the disruption was due to damaged insulators which caused a failure to properly supply power.

2017 tunnel flooding

On 7 October 2017, a 20-hour long disruption of services started due to flooding in the tunnels between Bishan and Braddell stations due to a faulty drainage system, resulting in disruption of train services between Ang Mo Kio and Marina South Pier stations in both directions for several hours. A trackside fire between Raffles Place and Marina Bay stations further exacerbated the disruption.

Train services between Newton and Marina South Pier were restored on the day itself at about 9.20pm while full train service resumed at 1.36pm the following day after overnight efforts to clear the water in the tunnel. It was discovered that the overflowing in the tunnel was caused by a malfunction in the water pumping system, which has since been repaired.
