1993 Clementi train collision

On 5 August 1993, before opening, a maintenance vehicle spilt oil on the tracks between Clementi and Jurong East. The first ten trains reported braking problems, then the eleventh train from Jurong stopped at the Clementi station for two minutes longer than scheduled due to it using its emergency brakes to stop at the station at 7.50am, before being hit by another train when it failed to stop in time. 156 passengers were injured by the collision.

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.

2016 Pasir Ris accident

At about 11.08am on 22 March 2016, two SMRT track-maintenance trainee staff were killed after a 151 train approaching Pasir Ris station ran over them,, resulting in a temporarily service disruption between Pasir Ris and Tanah Merah.

In the investigation report, the two trainee staff joined SMRT in January 2016 and worked as technicians under a technical team of 15 staff led by a supervisor and were tasked to go down to the tracks to investigate an alarm triggered by a possible signalling equipment fault close by the station. An operator cited that they were granted access to the tracks, but did not coordinate with a Signal Unit in the station to ensure trains could not travel in the area where the team was.

2017 Joo Koon train collision

On 15 November 2017 at 8.18am, 2 151A trains collided at Joo Koon station. A train fault caused the first train heading in the direction of Tuas Link to stall at the station. A minute later, a second train stopped behind the first and then "moved forward unexpectedly", resulting in the collision. 36 passengers and 2 SMRT staff sustained light to moderate injuries, and have been conveyed to nearby hospitals.

Investigation found that the first train had a safety protection feature removed when it went over a faulty signalling circuit. That safety protection feature was designed to fix a known bug which wrongly designated the six-car train as a three-car train under certain circumstances. While the first train was being detrained and the automatic platform doors were opened, a separate protection module was activated to block off the entire length of the platform at Joo Koon station. The module notified the second train's signalling computer that the Joo Koon station's westbound platform was occupied and to stay clear of the platform. The second train stopped at the correct distance behind the first train while the automatic platform doors were open. However, once the doors were closed, the platform length protection module was removed. When the signalling on the second train detected the first train as only three cars instead of six, it started moving to close the perceived gap between both trains for the distance of three cars, thus allowing the acceleration of the second train and the rear-end collision with the first train.
