The recent disruption of Aerotrain operations at KLIA Terminal 1 was not due to a mechanical failure but a minor software bug, says transport minister Loke Siew Fook.
“It wasn’t a breakdown but a technical glitch, a software bug.
“In any system, there will be occasional disruptions, bugs and other issues that must be addressed and fixed.
“The disruption was resolved within 15 minutes,” Bernama reported him as saying after opening the Asean-China International Rail Transit Forum 2025 today.
Loke expressed regret over the disruptions for the past month but said the Aerotrain service continued to record high passenger volumes, with 1.5 million passengers a month and hundreds of trips daily.
On Monday, KLIA issued an official apology for the temporary pause in Aerotrain operations that morning.
In a post on X, the airport explained that the 15-minute delay was caused by a door malfunction and shuttle buses were deployed during that time to maintain connectivity.
“Services resumed at 11.01am and operations are now back to normal. Thank you for your patience,” it said on its @KLIA_my account.
X user @afiqmukhtar highlighted the service disruption at 10.52am, asking why the Aerotrain had “broken down again”.
“Millions (spent for) repairs but it still cannot hold passengers to capacity. What is this?” he said, also tagging Prime Minister Anwar Ibrahim, Loke and Malaysia Airports Holdings Bhd in his post.
On a separate matter, Loke said the third-generation electric train service (ETS3) project to Johor Bahru was progressing as planned, contrary to claims by some parties.
“It is definitely inaccurate to say it has been delayed. I mentioned a few months ago that the ETS3 project will be implemented in phases.
“It is not a delay,” he said.
Loke said the first phase of ETS3 is already operational up to Segamat, while the second phase to Kluang is set to begin service before Aug 31.
The third phase leading to Johor Bahru Sentral is expected to be completed by the end of the year.
