Kuala lumpur: The upgrading works on Phases 2 and 3 of the Kelana Jaya Line signalling system, initially scheduled to begin on Aug 9, have been postponed to Sept 6. Prasarana Malaysia Berhad (Prasarana) stated that this rescheduling is to allow additional testing of the new Phase 1 signalling system to ensure it is fully functional and efficient.
According to BERNAMA News Agency, the additional tests are crucial to assess the system’s performance under actual operating conditions and to minimise the risk of future service disruptions. For Phase 1, the upgrading works were carried out during night maintenance hours as the affected areas were mainly around the depot and did not involve the main train operating route. This upgrading project is part of a long-term solution following the signalling system disruption incident in November 2022.
Prasarana outlined that Phase 2 works are scheduled for Sept 6, 7, 14, 15, 21, 27, and 28, as well as Oct 11 and 12, covering stations from KLCC to Gombak. Phase 3 is planned for Nov 1, 2, 8, 9, 15, 16, 29, and 30, involving the stretch from Lembah Subang to Ampang Park. As a result, the affected stations will open to passengers at 9 am, later than the usual 6 am start, while stations not involved in the system testing will operate as usual.
Prasarana will provide free shuttle buses and vans to connect the affected stations and ensure smooth passenger movement. Passengers will receive assistance from station staff, auxiliary police, and Prasarana Troopers (trained volunteers) stationed at the affected and interchange stations. Information boards and leaflets will be available at stations and bus stops to guide commuters.
Prasarana apologises for any inconvenience caused by the change in the upgrade schedule and appreciates the patience and cooperation of passengers throughout this period. The new SelTrac Generation 8 signalling system provides real-time data analysis, enhanced cybersecurity, and improved communication stability, and is expected to extend the lifespan of the existing signalling system by up to 20 years.
