Kelana Jaya LRT Line Shuts Down For 1 Week!
At 4:55 AM on 9 November 2022, Rapid KL announced that they are suspending sixteen stations on the Kelana Jaya LRT line for 7 days!
In addition, all other LRT stations will end their services earlier at 11 PM. Here is their official notice, with my English translation:
Kemaskini Gangguan Perkhidmatan LRT Laluan Kelana Jaya:
16 stesen LRT dari Stesen Kelana Jaya hingga Stesen Ampang Park digantung operasi selama 7 hari bermula hari ini.
Lain-lain stesen beroperasi seperti biasa dan akan menamatkan perkhidmatan lebih awal iaitu pada jam 11 malam.

Other stations will operate as usual and will end services earlier at 11pm.
Kelana Jaya LRT Line Disruption Caused By ATC System
At a special media briefing at 10:30 AM on Wednesday, 9 November 2022, Prasarana CEO Mohd Azharuddin Mat Shah stated that the disruption of the Kelana Jaya LRT line was due to faulty electronic components in its Automatic Train Control (ATC) system.
The disruption, which resulted in the loss of signal between the control centre and also the trains caused the trains to be dysfunctional automatically between the Kelana Jaya station and the Ampang Park station.
This is a serious problem that has never happened before. Rapid Rail is assisted by a special team from original equipment manufacturer (OEM) Thales Group from Toronto, Canada, to find short and long-term solutions. This includes tests on existing devices and software.
Efforts will be made by RapidRail to address the problem. Free feeder bus service will be provided for passengers and to reduce congestion at the affected stations.
He said that as of 11 AM today, Rapid KL has provided 69 feeder buses to ferry passengers for free on the Kelana Jaya LRT route.
The 7-day shut down will give Rapid KL engineers time to analyse and identify the problem, and hopefully solve the problem long enough for an ATC replacement to be completed.
In response to a question, Prasarana CEO Mohd Azharuddin Mat Shah said that they had already foreseen the need to replace the ATC system because it’s at the end of its lifespan, and will upgrade it after this incident.
However, he shared that the RM150 million ATC system replacement will take a few months.
