The CEOs of LTA and train operator SMRT are spoke at a press conference at 11am on Wednesday morning after a 3.5-hour disruption crippled the North-South and East-West Lines (NSEWL).
During the press conference, SMRT CEO Desmond Kuek apologised to affected commuters. He said: "We would like to apologise to commuters and all who were inconvenienced by the MRT disruptions... SMRT mobilised all engineering staff to conduct checks. We made some rectifications last night, but will continue to check on systems."
SMRT's Director of Trains, Mr Lee Ling Wee provided a detail timeline of the events that happened. "At 8.35pm our main consideration was that we didn't want passengers detrained on track. By 10.35pm, train service had resumed, but still had sporadic power trips."
He add that "We are not 100 per cent sure on the root cause... We have an idea of where to check. We'll look through the data and find the root cause."
According to Lee, there are three possible causes – trains, tracks and power substations. Following overnight checks, trains have been ruled out as the problem.
