Commuters at Jurong East MRT station last Friday, when travel times were lengthened due to a train fault.
The update will be done after passenger service hours, said the Land Transport Authority (LTA) and rail operator SMRT on Friday.
Developed by Thales, the contractor in charge of the resignalling project, the update is expected to address “teething issues” that surfaced during the testing of the new system, which began full day tests on May 29.
Some of these issues which the update is expected to improve include alignment between train and platform screen doors, trackside-to-train communications and strengthening the signalling system’s main server.
“As we cannot rule out possible initial faults during the software update, engineers from LTA, SMRT and Thales will be on standby round-the-clock to closely monitor the transition and address faults,” said LTA and SMRT in a joint statement on Friday.
They added: “Should a fault occur, we seek the public’s understanding.”
