Second track fault in three days affects city-bound trains on North-South Line

Train services on the North-South Line were delayed briefly on Friday (27^th October) morning due to a track fault between Ang Mo Kio and Bishan stations. This is the second time in three days that the same stretch of line was hit by a track fault. It was not clear if the faults are related.

SMRT first tweeted about a 20-minute delay from Ang Mo Kio to Bishan in the direction of Marina South Pier at 5:56am, adding that free regular bus services had been activated. Normal service resumed at around 6:30am.

On Wednesday, trains had to run at lower speeds over a 150m stretch between Bishan and Ang Mo Kio for much of the day due to a track fault. Electrical arcing had caused a rubber insulator to melt along the tracks near the Bishan swimming complex, creating a gap between running rails. This caused bunching up of service on the heavily-used line during peak hours.
