A signalling fault that occurred on Monday morning (Mar. 29) disrupted morning commutes, affecting train service on the stretch of the North South line that goes to the CBD area.

While there was still train service for most of the morning, bridging bus services were activated and SMRT advised commuters to expect additional travel time if they took the train.

Up to 45 minutes additional train travel time

At 5.47am, SMRT posted an update that the commute between Raffles Place and Toa Payoh was extended by 25 minutes due to a signalling fault.

At 6.21am, train service between Novena and Raffles Place was restored.

At 7:30am, SMRT posted another update that train travel between Bishan and Raffles Place could take an additional 45 minutes.

Commuters advised to avoid North South Line to the city

SMRT said in a tweet at 6:51am that commuters to the city were advised to make "alternative travel arrangements" to avoid taking the North South Line.

Commuters from the north were even advised to take the North South Line in the opposite direction, to transfer to the East West Line via Jurong East.

As of 8:35am, the situation had yet to improve, with SMRT repeating its announcement of 45 minutes' additional travel time, and continuing to advise commuters to avoid the North South Line.

At 9:48am, SMRT announced that a reset of the signalling system would be conducted at 10am, and that there would be no train service between Toa Payoh and Marina South Pier for around 15 minutes.

Train services resumed by 10:46am

Train services resumed by 10:46am, and bridging bus services had ceased, according to SMRT.

This was after a successful reset of the signalling system, which SMRT said was delayed till 10am "to keep train services moving during the morning peak and fix the technical fault after the peak," in an update to its Facebook post on the matter.
