SHAH ALAM, March 12 — Disruptions to the Aerotrain service at Kuala Lumpur International Airport (KLIA) since July last year were caused by technical issues involving rolling stock, signalling systems and power distribution, Transport Minister Anthony Loke said.
The problems were identified following investigations into earlier service interruptions affecting the airport’s automated people mover system.
However, Loke said the service has achieved full operational status since last month.
“Based on the latest records as of February 8, 2026, the Aerotrain transport system has reached 100 per cent operational status with 77,741 total return trips and has successfully carried 11.78 million passengers,” he said in a written parliamentary reply.
He was responding to a question from Senator Datuk Ahmad Datuk Ibrahim on the cause of disruptions to the new KLIA Aerotrain service since its resumption in July last year, following a suspension in March 2023 due to a major breakdown.
Loke said the current Aerotrian model differs technologically from the previous system used at the airport as it utilises a more capable and efficient model.
He said the new system uses the Alstom APM 300R, compared with the earlier CX 100.
“Both models (Alstom APM 300R and Alstom Bombardier CX 100) have the same physical specifications such as width, height, rubber-tyre guidance system and driverless operation.
“However, the APM 300R model uses a modern AC motor with the latest inverter compared with the older CX 100 model that uses an older DC motor.
“This allows for better energy efficiency while supporting larger passenger volumes at one time,” he said.
Loke added that MAHB will continue to monitor the Aerotrain system to ensure smooth operations.
