Malaysia Airports Holdings Bhd (MAHB) has refuted circulating claims that KLIA’s newly launched Aerotrain service suffered a breakdown less than a week after commencing operations.
In a formal statement responding to viral social media posts, MAHB clarified that the train service was only temporarily suspended at 11:00 a.m. due to heavy rainfall, which caused water accumulation within the train tunnel.
The statement emphasized that passenger transfers to the satellite terminal remained uninterrupted, as shuttle bus services were activated promptly.
“The tunnel’s drainage system is equipped with pumps designed to manage water ingress during adverse weather conditions. However, one of the pumps experienced a technical fault during today’s downpour, which hindered the automatic drainage of accumulated water.
“As a precautionary measure, train services were suspended until the water was manually cleared and the tracks were declared safe. Operations resumed at 12:15 p.m., following full clearance from our technical and safety teams,” the statement said.
MAHB further stated that its technical teams are closely monitoring the system to ensure that any operational adjustments, if required, can be implemented without delay.
“We appreciate the public’s patience and cooperation as we continue to fine-tune this new system,” the agency added.
Earlier, Facebook user Ahmad Ramadzan Soid posted on Wednesday that one of the Aerotrain units had allegedly broken down, though another remained operational. Several social media users speculated that a malfunctioning door may have been caused by passenger interference.
On Thursday, travel blogger CK Ng also posted that the Aerotrains were not in service, and that passengers were instead transported to the satellite terminal via bus.
KLIA’s Aerotrain system, which had served as the core of its internal transport since 1998, suffered a major breakdown in 2023. Buses have since been used to shuttle passengers between Terminal 1 and the satellite terminal, which handles most international arrivals and departures.
The upgraded Aerotrain system officially resumed service on July 1, operating with three trains, each capable of accommodating up to 270 passengers.
