He said with the modem and power supply for the tracks having been replaced, the problem was now rectified but the line still needed to be tested tomorrow.

“The Land Public Transport Agency (APAD) will also need to certify the Thales Group experts’ confirmation that the rail line is safe and stable for use before we can resume operations,” he said at a press conference at the Lembah Subang Rapid Rail depot.

“If there are no more problems, then we will resume services with Prasarana making an announcement at 6pm the day before.”

On Wednesday, Prasarana announced that services between the Kelana Jaya and Ampang Park LRT stations would be suspended for a week. It involved a total of 16 stations.

It could not determine the root cause of the automatic train control (ATC) system malfunction that led to the disruption of services.

The company said it sought help from Thales Group, the original equipment manufacturer, to send over its experts to look into the problem.

Wee said tomorrow’s test would see the running of the train along the Kelana Jaya LRT line for a full day.

“We want to ensure the train can run for a full day, and the Thales Group experts must then make an assessment based on this.”
