You might have come across a The Straits Times article today about 2 LRT trains colliding on the Sengkang line last evening (3 Jul 2017).
LTA and SBS Transit Ltd would like to clarify that the article is erroneous and misleading, as there was no collision on the Sengkang LRT system.
The incident last evening involved a coupled two-car train which had stalled in between the Sengkang Town Centre and Renjong Stations. The two Light Rail Vehicles were travelling as one train on the system.
The sudden stalling may have caused some passengers who were not holding onto the standing poles/grab bars to lose their balance, and may have given the wrong impression that the trailing train-car had hit the one in front. SBS Transit staff subsequently reset the fault and manually drove the coupled train to Renjong Station to detrain passengers safely.
