Train service on the North-South Line (NSL) was disrupted for about half an hour on Tuesday (Apr 26), less than 12 hours after four train lines were affected by a power trip in another incident. This was also the third disruption on the NSL in less than a week.
On Tuesday morning, a "traction power fault" stopped train service between Kranji and Woodlands MRT stations on the NSL.
In a Facebook post, SMRT apologised and said it is "currently investigating the cause to determine if it is related to last night’s power fault".
On Monday, a larger number of stations on the NSL - from Jurong East to Kranji - were affected. Train services on the East-West, Circle and Bukit Panjang LRT Lines were also disrupted, the first time that trains on all of these lines were affected at the same time, transport operator SMRT said. It added that the power trip was traced to a "power dip" at the Buona Vista power intake station.
Singapore's MRT system has experienced a number of breakdowns since Apr 21, when there was no train service from Marina South Pier to Newton stations. Later in the day, the North-East Line was also hit by a train disruption. Train services were unavailable between Chinatown and Farrer Park stations in both directions.
This was after Transport Minister Khaw Boon Wan announced in a blog post that the NSL had passed the 100-day major incident-free milestone.
Those affected in Monday's power trip incident can collect fare refunds within the next 14 days from passenger service counters at any SMRT train station, said SMRT.
