===1993 Clementi train collision===
On 5 August 1993, before opening, a maintenance vehicle spilt oil on the tracks between {{Stn|Clementi}} and {{Stn|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.<ref>[//eresources.nlb.gov.sg/INFOPEDIA/articles/SIP_814_2004-12-31.html "First MRT accident - Infopedia"]. National Library Board.</ref>
 
===2015 train disruption===
On 7 July 2015 at about 7.20pm, both the {{NSL|b=}} and {{EWL|style=font-weight:normal;}} were temporarily disrupted due to massive power trips detected along the line. Train service resumed at 10.35pm at a reduced speed.<ref>[//www.lta.gov.sg/content/ltagov/en/newsroom/2015/7/2/lta-media-statement-nsewl-service-disruption-2.html "LTA Media Statement: NSEWL Service Disruption"]. Land Transport Authority (7 July 2015).</ref> The cause of the disruption was due to damaged insulators which caused a failure to properly supply power.<ref>[//web.archive.org/web/20160427123605/www.channelnewsasia.com/news/singapore/power-trip-on-mrt-network/2733272.html "Power trip on MRT network due to power fault on NSEWL"]. Channel NewsAsia. Archived on 27 April 2016.</ref>
 
===2016 Pasir Ris accident===
At about 11.08am on 22 March 2016, two SMRT track-maintenance trainee staff were killed after a [[Kawasaki Heavy Industries C151|C151 train]] approaching {{Stn|Pasir Ris}} station ran over them,<ref>[//www.straitstimes.com/singapore/transport/smrt-accident-2-men-were-part-of-group-of-15-led-by-supervisor-and-walking "SMRT accident: 2 men were part of group of 15 led by supervisor and walking facing oncoming train"]. Straits Times (23 March 2016)</ref>, resulting in a temporarily service disruption between {{Stn|Pasir Ris}} and {{Stn|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.<ref>[//www.channelnewsasia.com/news/singapore/smrt-acknowledges-lapse/2630038.html "SMRT acknowledges safety procedure not followed before fatal accident"]. Channel NewsAsia (23 March 2016).</ref>
 
===2017 Joo Koon train collision===
On 15 November 2017 at 8.18am, 2 [[Kawasaki Heavy Industries & CSR Qingdao Sifang C151A|C151A]] trains collided at {{Stn|Joo Koon| station}}. A train fault caused the first train heading in the direction of {{Stn|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.<ref>[//www.lta.gov.sg/content/ltagov/en/newsroom/2017/11/2/joint-statement-by-the-land-transport-authority-lta-smrt---joo-koon-train-incident.html "Joint Statement by the Land Transport Authority (LTA) & SMRT - Joo Koon train incident"]. Land Transport Authority (15 November 2017).</ref><ref>[//www.lta.gov.sg/content/ltagov/en/newsroom/2017/11/2/joint-statement-by-the-land-transport-authority-lta-smrt---update-on-train-incident-at-joo-koon-station.html "Update on Train Incident at Joo Koon Station"]. Land Transport Authority (15 November 2017).</ref><ref>[//www.channelnewsasia.com/news/singapore/joo-koon-train-collision-total-number-of-injured-rises-to-38-9420752 "Joo Koon train collision"]. Channel NewsAsia (19 November 2017).</ref>
 
Investigation found that the first train had a safety protection feature removed when it went over a faulty signalling circuit.<ref name='faultsignal'>[//web.archive.org/web/20171117175406/www.straitstimes.com/singapore/transport/inadvertent-removal-of-software-fix-led-to-collision "Joo Koon collision: 'Inadvertent removal' of software fix led to collision"]. Adrian Lim (Straits Times, 16 November 2017)</ref> 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.<ref name='faultsignal'/> 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 {{Stn|Joo Koon| station}}. The module notified the second train's signalling computer that the {{Stn|Joo Koon| station's westbound platform}} was occupied and to stay clear of the platform.<ref name='faultsignal'/> 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.<ref name='faultsignal'/>
