Circle Line 6
Nicoll Highway Collapse
On 20 April 2004 at 3.30pm, the construction site of the 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. 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. The collapse also resulted in the completion of Circle Line 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. 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" C830C train (846).
