SMRT Corp said train service on the Tuas West Extension between Gul Circle and Tuas Link will resume operations on Monday, allowing authorities to carry out investigations.
Thirty-six people were injured after two trains collided at Joo Koon MRT station on Wednesday, in what Transport Minister Khaw Boon Wan described as "an awful day".
The collision was caused by a software glitch in the East-West Line (EWL) signalling system, authorities had said on Wednesday evening.
"Given this finding, LTA and SMRT have decided to isolate for up to one month the operations of the Tuas West Extension, which runs on the new signalling system, from the rest of the East-West Line, which runs on the old signalling system," the Land Transport Authority (LTA) said in a statement on Thursday.
The LTA said that trains will go through an additional layer of control measures and manual checks before they are deployed.
Bridging bus services will be available between Joo Koon station and Gul Circle station.
LTA added that 33 buses on Thursday morning had been deployed on the bridging bus service between Joo Koon and Tuas Link MRT stations "at headways of three to five minutes" and that "service was satisfactory". These bridging bus services will continue to be provided until Sunday evening.
