Third train disruption in less than a week: Circle Line resumes service after signalling fault
The Circle Line has resumed service after a signalling fault between Paya Lebar and Marymount MRT stations caused delays on Tuesday (Feb 11) morning.
According to train operator SMRT, the signalling system fault occurred at around 8.11am, affecting a total of eight stations.
«The fault caused trains to stop, and power to the affected sector was tripped,» said SMRT.
«Power was restored within five minutes, and train movement resumed at 8.20 am.»
The Central Automatic Train System, however, was «sluggish» and affected the controllers' ability to manage train movements effectively, the train operator explained.
Hence, it took about 30 minutes for the entire Circle Line to return to normal service.
SMRT said that during the morning peak period, key interchange stations such as Serangoon, Buona Vista, Botanic Gardens and Bishan typically require one or two trains to clear crowds.
Due to the delay on the Circle Line, it took about three trains to ease the congestion.
