Trains on two main transit lines in Singapore will run at reduced speeds during peak hours as authorities investigate a power fault that froze evening commutes across more than 50 stations Tuesday, Bloomberg reported.
Commuters can expect trains on the North-South and East-West lines operated by SMRT Corp. Ltd. to arrive at intervals of five to seven minutes Wednesday, the Land Transport Authority said on its Facebook page.
The trains normally arrive at two- to three-minute intervals during the morning peak hours.
The North-South link will also be shut from 11 a.m. to 4 p.m. for further checks, the regulatory body said.
All trains on the two lines were halted for more than three hours yesterday, with full services resuming at 10:35 p.m., after a suspected power surge caused by a faulty train triggered protective shutdowns across both networks, it said.
“I am extremely concerned,” Transport Minister Lui Tuck Yew said on his Facebook page late Tuesday.
“I am sorry that so many commuters experienced massive disruptions to their journeys.”
LTA and SMRT engineers will need more time to “ascertain the situation definitively”, the LTA said on Facebook.
All the trains affected Tuesday reached the nearest platforms, and passengers disembarked safely, SMRT said.
In July 2014, the LTA fined SMRT S$1.6 million (US$1.2 million) for four train service disruptions.
Rival train operator SBS Transit was fined S$50,000 for one incident.
