KLIA aerotrain to undergo software upgrade after 20,000 operational hours

KLIA aerotrain services will be halted overnight from midnight to 5am for a software upgrade that has been scheduled due to the train reaching 20,000 continuous operational hours. Malaysia Airports Holdings Bhd (MAHB) explained that the upgrade aims to improve the aerotrain's operational endurance and support its long-term performance. The enhancement will be executed in two stages, with aerotrain services being interrupted from midnight to 5am each time.

During the first phase, from October 8 to 17, field testing will be carried out, during which the software update will be installed and evaluated under real-world operating conditions. The performance and functionality of the updated system will be verified and subjected to an independent safety assessment before the second phase. This second phase, scheduled for November 28 to December 1, will ultimately result in the permanent deployment of the upgraded system on the aerotrain.

Despite the brief service disruptions, passengers can rest assured that bus services will continue to operate throughout the upgrade and testing periods, ensuring seamless transfers between the main terminal and satellite building. The KLIA aerotrain system has consistently maintained a remarkable 99.9% availability since June, having completed 167,481 return trips and transported approximately 23.55 million passengers over the past 18 months.

MAHB's top priority is to guarantee that the aerotrain continues to deliver a reliable and smooth service to passengers at KLIA. KLIA's chief operating officer, Adam Nicholas Wilson, emphasized that planned activities, such as this software upgrade, are part of ongoing efforts to maintain this high level of performance and uphold the system's reliability over the long term.
