KUALA LUMPUR – Malaysia Airports Holdings Bhd (MAHB) has confirmed that the aerotrain service at Kuala Lumpur International Airport (KLIA) Terminal 1 has resumed normal operations after a temporary disruption yesterday evening.
The disruption occurred at approximately 8.30 pm, prompting the airport operator to immediately implement contingency measures, Bernama reported.
“Shuttle buses were deployed immediately to ensure uninterrupted passenger transfers between the Main Terminal and Satellite Building. We can confirm that no passengers missed their flights during this period, affirming the efficiency of our contingency plans,” the company said in a statement.
By 9.27 pm the same evening, one train had been safely restored to service. After undergoing multiple rounds of safety and operational testing, both trains are now operating normally.
The incident took place during the defect liability period of the newly commissioned aerotrain system.
“An urgent technical meeting was convened with project contractors Alstom and the IJM-Pestech Joint Venture (IPJV), which is responsible for the design and installation of the power distribution system. The root cause of the disruption is under investigation, with the contractor expected to issue a separate detailed technical report,” MAHB added.
In the meantime, MAHB has implemented additional safety measures, including thermographic scanning and diagnostic tests to verify the system’s integrity.
The airport operator also stated it will closely monitor the rectification work carried out by the contractor.
“This latest incident is particularly disappointing, given that the aerotrain system had undergone a rigorous testing, commissioning, and certification process prior to its launch. This process involved independent consultants, safety professionals, and regulatory authorities to ensure compliance with all safety and performance standards,” it said.
As part of further precautionary steps, MAHB will appoint an independent assessor to conduct a comprehensive review of the power supply design and installation quality.
“Malaysia Airports remains fully committed to ensuring that the KLIA aerotrain system is safe, reliable, and capable of delivering the high standards of service that our passengers expect and deserve,” it concluded. – October 16, 2026
