"We will have to continue to dive into root causes whenever incidents like these happen and take firm actions. "We apologise for the inconveniences caused," LTA added. To have two MRT faults occur over two days is "very unfortunate and frustrating", LTA said, noting that the faults happened on two separate lines, each for different reasons. These replacement works will be completed by June. The faulty insulator has been replaced and LTA is working with SBS Transit to accelerate an ongoing programme to replace insulators along the NEL with ones that have a better design. This led to the overhead catenary system at Buangkok station, which supplies power to the trains, to fail. LTA on Monday said the cause of the NEL disruption has been traced to a faulty insulator. On Sunday morning, train services between Punggol and Serangoon stations on the North East Line (NEL) - run by SBS Transit - came to a halt for about three hours due to a power fault. Commuters travelling to the city should take the East-West Line, Circle Line, North East Line and Downtown Line instead, it added. In its initial tweet at 5.47am, SMRT said commuters travelling between Raffles Place and Toa Payoh should add 25 minutes time to their journey.Īt 6.40am, SMRT advised commuters to avoid taking trains between Bishan and Marina South Pier stations. Mr Nair ended up taking a regular bus to Bugis, where he said he planned to take a private-hire car to his workplace in Tanjong Pagar. There were a lot of people waiting for taxis and ride-hailing services." There were no representatives from SMRT at the bus stop." "I tried looking for the shuttle bus service but there was none. It took more than 30 minutes for Mr Nair to reach Toa Payoh station and he said it was "chaotic" when he alighted at Novena. The platforms at the station were packed with commuters, he said. Safety officer Arjun Nair, 26, boarded a train at 7.30am, also at Khatib station, but had to alight at Ang Mo Kio 10 minutes later. "If we were told at the start of our journey at Khatib (about the fault), we would have opted for an alternative mode of transport." Guidance for commuters needs to be improved. (There needs to be) better and more prompt announcements. "Not everyone follows SMRT on Twitter or Facebook, especially aunties and uncles. Mr Chan, who was also affected by a train fault two weeks ago during morning peak hour, lamented the lack of communication by SMRT. It was much smoother there, he said, as there were SMRT staff around to guide commuters and control the crowd. He took 40 minutes, instead of the usual 15 minutes, to get from Khatib to Toa Payoh station, where he alighted to take a bus. It was only then that we heard the announcement about the signalling fault." "We alighted again and waited for the next train. Mr Chan got on another train at Ang Mo Kio but as he neared Bishan station, there was another announcement that the train was terminating at Bishan. The trains were packed and social distancing was "non-existent", he added.
