Root cause of MRT services disruption still elusive for SMRT, LTA engineers

An independent consultant will also investigate.

Despite extensive system checks, engineers from SMRT and the Land Transport Association (LTA) are yet to discover the root cause of the July 7 MRT service disruption.

“Despite carrying out a comprehensive second round of checks, we have yet to definitively identify the root cause of the disruption,” LTA said in a statement.

LTA added that it will bring in an independent consultant to help with the investigations.

“An independent consultant, who specialises in transit power systems, will be engaged to look into the overall conditional assessment of the entire power supply infrastructure and other railway trackside installations. The assessment may start as soon as this month once the experts are onboard. In the meantime, LTA and SMRT will continue checks on the system,” the statement said.

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
