Signalling disruption causes up to five-hour delays for KTM Komuter, ETS

A signalling system failure caused significant delays of up to five hours for KTM Komuter and ETS train services in Malaysia. Repair works were completed, and services have largely returned to normal, with the operator offering fare refunds to affected passengers.
Why it matters
Infrastructure failures in public transportation highlight the challenges of maintaining aging rail systems and the impact on daily commuter reliability.
KUALA LUMPUR: A signalling system disruption between Kalumpang and Kuala Kubu Baru on Saturday (Sept 26) left KTM Komuter and ETS services delayed by up to five hours.
In a statement on Sunday (Sept 27), Keretapi Tanah Melayu Berhad (KTMB) said KTM Komuter's worst delay hit Train No. 2389 at 230 minutes, while ETS service EP9138 (KL Sentral-Butterworth) had a 305-minute delay.
KTMB said preliminary checks traced the disruption to damage to a system component, which sparked and disrupted the signalling system.
The cause of the component damage, however, is still under further investigation.
"The signalling system disruption had a knock-on effect on the movement and schedules of other trains passing through the sector, particularly services to and from the north," the statement read.
