Following a massive disruption to the North-South and East-West MRT lines on Tuesday evening (Jul 7) that affected 250,000 commuters during evening peak hours, SMRT has announced measures to prevent a repeat of the incident.

SMRT had said the disruption was due to multiple power trips detected on both lines. It has ruled out a defective train as the cause of the power fault. The root cause of the breakdown has yet to be identified.

The transport operator on Friday said it will reschedule long-term track upgrade and renewal programmes as necessary, so that priority for track access during limited maintenance hours at night can be given to immediate remedial actions that can safeguard the system.

SMRT said it will continue testing and investigations through the weekend by repeating the full cycle of checks and re-enacting where possible, conditions under which there was a series of power trips on Tuesday.

It is also working with external experts to review the robustness of the power network, and will find ways to segement it further in order to avoid a similar system-wide power failure.

"We have also brought in a number of retired SMRT staff with experience in network power issues to assist in investigations. At the same time, we have advanced the procurement of additional conditioning monitoring systems that were being developed jointly with R&D agencies," SMRT said.
