'Traction power trip' caused late-night disruption, blackouts on NSL and EWL
SINGAPORE: A traction power trip was what caused hour-long disruptions to train services along the North-South Line (NSL) and East-West Line (EWL) late on Wednesday night (Jul 12).
It also caused blackouts at several stations.
According to train operator SMRT, the power trip happened at around 11.35pm in the western sector of the both MRT lines, which affected service between Jurong East and Kranji stations, as well as between Queenstown and Tuas Link stations.
The fault was traced back to the Tuas Depot intake station, which supplies power to Tuas Depot, the East-West Line from Tuas Link to Jurong East stations, and the North-South Line from Jurong East to Kranji stations.
"As a result, trains travelling within the affected sectors on the network came to a halt, while some stations experienced momentary loss of electricity supply," said SMRT's vice president for corporate communications Patrick Nathan in response to queries from Channel NewsAsia.
He added that the Bukit Panjang LRT network was also hit as it draws power from Choa Chu Kang station along the affected stretch.
SMRT first tweeted about the disruption at around midnight, estimating that services would resume in about half an hour.
Train services between Tuas Link and Queenstown stations resumed at around 12.20am. However in an update at 12.30am, SMRT said that there was still no train service on the East-West Line between Jurong East and Choa Chu Kang due to the power fault.
Eventually at 1.20am, SMRT tweeted: "Cleared: Train service and bridging bus services have ended. Our engineers will continue to work and rectify the fault."
Train services from Jurong East to Choa Chu Kang remained closed until the end of service.
Mr Nathan said that SMRT's power engineers responded immediately to the incident and service recovery measures were taken, including activation of power supply from the Buona Vista intake station to restore power to parts of the NSL and EWL.
Investigations into what caused the trip are still being carried out, added Mr Nathan who apologised to commuters for the inconvenience caused.

North-South Line train delay: Rush-hour commuters affected due to signalling fault
SINGAPORE: Commuters travelling along the North-South MRT line were hit by delays during the evening peak period on Thursday (Aug 17), caused by a fault in the network's new signalling system.
It took about two hours before train services went back to normal.
Transport operator SMRT had asked commuters to use other MRT lines or make alternative transport arrangements, even as a team of engineers worked to rectify the fault.
"We are sorry that commuters’ evening journeys have been affected," it added.
At around 5.35pm, a signalling unit along the tracks near Ang Mo Kio saw a fault, which affected signalling communication to trains, SMRT said.
Trains came to a halt momentarily but service later continued, the operator added, with trains travelling at slow speeds between Ang Mo Kio and Bishan stations for "safety reasons".
Passenger Kannan told Channel NewsAsia that they had been asked to get off a packed northbound train at Newton station at around 6.15pm.
SMRT had announced that there had been a signalling fault at Ang Mo Kio, he said, adding that he managed to squeeze onto the next train but that it didn't move for more than five minutes.
The train operator first tweeted about the delay at 6.18pm.
However, commuters reported delays of up to double SMRT's initial estimated 20 minutes. Randy Peck told Channel NewsAsia that he had been waiting for a train at Raffles Place station for at least 30 minutes, while Tan Yi-Fan said in a Facebook comment that he had already been waiting for 40 minutes.
In a 7pm update, SMRT said commuters should expect a delay of 40 minutes, but added that train service was still available.
The transport operator added that free regular buses and bridging bus services were available between Marina South Pier and Ang Mo Kio in both directions.
By 8pm, the estimated delay had been cut to 15 minutes, SMRT said in a Twitter update. Train services eventually resumed at about 8.20pm, according to the transport operator.
The North-South and East-West Lines (NSEWL) have been affected by multiple disruptions since SMRT's engineers started full-day trials on weekdays to test its new signalling system. The transport operator had warned commuters of potential delays, as "intensive performance checks" continue.
Last month, SMRT Trains' CEO Lee Ling Wee said in a statement that it had "no choice" but to conduct checks for the new signalling system on the NSEWL throughout the day because it was being added to an already operational MRT line.

this morning pai again
and so suay today is PSLE Oral exam
Early morning commuters on Friday (Aug 18) were hit by twin disruptions on the train network, as signalling faults disrupted the entire Downtown Line (DTL) for about 35 minutes and caused major delays on the North-South Line (NSL).
Friday morning's disruptions came hours after Thursday evening's peak-hour train delay on the NSL due to a signalling fault near Ang Mo Kio station that took about two hours to clear.
Transport operator SMRT first tweeted about the NSL delay at 6.29am, warning commuters of a 30 minutes delay between Sembawang and Marina South Pier both bounds. Minutes later, the delay worsened to 45 minutes.
However, service on the entire DTL went down at about the same time. SBS Transit said in a tweet at 6.25am that there was no DTL service due to a signalling fault.
Service on the DTL resumed about 35 minutes later, SBS Transit said at 7am, adding that commuters should expect longer waiting times of about 15 minutes as the trains were being "progressively put into service".
"A joint team of engineers are working hard to restore train services as quickly as possible," SMRT wrote on Facebook at 7.45am. "We are sorry that this has affected your morning commute."
The transport operator later said at 8.30am that train services are progressively resuming to normal, albeit with 30 minutes delays due to congestion at the affected stations along the North-South Line.
Both transport operators said that free bus rides are available at designated bus stops on both the NSL and DTL.
*THIS STORY IS DEVELOPING
Hours after signalling faults threw the morning rush hour commute into chaos, rail operator SMRT has warned commuters of a second straight day of potential delays on the North-South Line (NSL).
In a Facebook post at 4.53pm on Friday (Aug 18), SMRT urged commuters planning to travel on the NSL to “plan ahead”.
“If you intend to travel on the North-South Line later, please plan ahead. You may experience longer train travel time,” the post read.
In a subsequent tweet, SMRT said that its engineers are “working hard to continue their checks and investigations”.
Earlier on Friday morning, signalling faults caused a three-hour delay on the NSL and disrupted the entire Downtown Line (DTL).
It affected thousands of commuters heading to work and students trying to reach their school on time for their Primary School Leaving Examination (PSLE) oral exams.
The Ministry of Education told students who were late for the oral exams not to worry as arrangements had been made for those who arrived late, and that they did not need to pick up excuse letters at the affected train stations.
According to SMRT, signalling experts and engineers are still checking the system to identify the root cause of the Friday morning delays.
This came after a signaling fault near Ang Mo Kio on Thursday evening also disrupted the NSL, causing delays of more than two hours.
