Staff from the track network maintenance department, car stock department (rolling stock), and signaling and communication wayside department, have been working over three full-time shifts over the last two nights, with each shift involving 50 staff members.

“The rehabilitation work is progressing smoothly and is expected to be completed within three days, as announced by the transport minister,” LRT operator Prasarana Malaysia Bhd said in a statement.

“Immediately after the rescue and evacuation work that night (Monday), the rehabilitation team began assessing the damage and conducting preliminary work, before starting the rehabilitation work.”

As of last night, five of the six derailed carriages had been lifted, which Prasarana called the most challenging part of the restoration efforts.

“Today’s work is focused on the final carriage and work related to removing the train, which will then be taken to the Kelana Jaya LRT Depot in Subang.”

The collission is being investigated by a special task force under the transport ministry, which has been given two weeks to complete its probe.

The task force is led by Isham Ishak, the transport ministry’s secretary-general.

In a statement today, Wee said human error was only one factor in the crash, having earlier revealed that one of the trains, which was operated manually and wasn’t carrying passengers, was travelling in the wrong direction when the crash occurred.

He added that many other factors, including a range of technical and operational components, would be taken into account in the investigation.
