==={{CCL|b=}} 6===
 
On 17 January 2013, the Land Transport Authority announced '''{{CCL|b=}} 6''' which will close the circle, running between {{Stn|Marina Bay}} and {{Stn|HarbourFront}}. It will be a 4 km extension with 3 stations.<ref>[//www.lta.gov.sg/content/ltagov/en/upcoming_projects/rail_expansion/circle_line_6.html "Circle Line Stage 6"]. Land Transport Authority. Retrieved 24 June 2020.</ref>
 
 
===Nicoll Highway Collapse===
 
On 20 April 2004 at 3.30pm, the construction site of the {{Stn|Nicoll Highway| station}} collapsed, apparently when a retaining wall used in the tunnel's construction gave way. The accident left a collapse zone 150m wide, 100m long, and 30m deep. Four workers were killed, with three more injured and one body which was never recovered.<ref>[//web.archive.org/web/20170719211131/www.todayonline.com/singapore/fridays-fatal-mishap-worst-worksite-accident-2004-nicoll-highway-tragedy "Friday’s fatal mishap among worst worksite accidents since 2004 Nicoll Highway tragedy"]. TODAY. Archived on 19 July 2017.</ref> Consequently, the station site was moved around 100m south of the initial location. Moreover, the tunnels between Promenade and Stadium were constructed on an alignment that bypassed the collapsed area.<ref>[//eresources.nlb.gov.sg/newspapers/Digitised/Article/today20050930-1.2.10.2.3 "NICOLL HIGHWAY PROJECT RESTARTED"]. TODAY (9 September 2005).</ref> The collapse also resulted in the completion of {{CCL|b=}} 1 being pushed back from 2008 to 2010.
 
 
===2016 train disruptions===
 
In late August 2016, intermittent signal interference led to a five-day series of train disruptions. The issue reappeared again in November.<ref>[//www.todayonline.com/singapore/no-service-6-circle-line-stations-disruption-caused-signal-fault-widens "Signal interference issue plagues Circle line again"]. TODAY.</ref><ref>[//www.straitstimes.com/singapore/transport/circle-line-signal-fault-that-caused-train-disruptions-on-wednesday-morning "Circle line signal fault that caused train disruptions on Wednesday similar to problem in September: LTA, SMRT"]. Straits Times (2 November 2016)</ref> A team of data scientists explored the data and discovered via a Marey Chart visualization that it was caused by hardware problems, sending errant signals from a "rogue" [[Alstom Metropolis C830C|C830C train (846)]].<ref>[//blog.data.gov.sg/how-we-caught-the-circle-line-rogue-train-with-data-79405c86ab6a "How the Circle line rogue train was caught with data"].
