KTMB Foils Cable Theft on Johor Electrified Corridor, Preventing Further Signalling Disruption

JOHOR BAHRU, February 2026 — Keretapi Tanah Melayu Berhad (KTMB) has intercepted an attempted cable theft along the Kempas Baru–Kulai corridor in Johor, preventing further disruption to services on one of the southern sector’s mixed-traffic routes. The incident, detected at approximately 2050 hrs on 20 February 2026 following a signalling anomaly, involved the severing of an estimated 250 metres of four-core railway cable at kilometre point 728.25. Auxiliary police detained a suspect at 2347 hrs and handed the individual to the Royal Malaysia Police for investigation.

The affected section forms part of KTMB’s double-tracked electrified network in Johor, used by both Electric Train Service (ETS) intercity operations and KTM Komuter services. ETS trainsets on this corridor operate at speeds of up to 140 km/h under centralised traffic control. Cable integrity is critical to maintaining signalling continuity, telecommunications links and supervisory control functions. Any interruption typically necessitates restrictive working procedures, including manual block authorisation and temporary speed reductions, directly affecting headway and punctuality.

KTMB previously reported that infrastructure-related incidents, including cable interference, resulted in 562 hours of ETS delays and 741 hours of KTM Komuter delays in 2025, underscoring the operational exposure associated with wayside asset vulnerability. While fibre-optic cables have negligible scrap value, severance can immediately disrupt interlocking communications and traction power SCADA systems, indicating that the risk profile extends beyond commodity-driven copper theft.

The network is regulated under the Railways Act 1991 (Act 463) and the Land Public Transport Act 2010 (Act 715). KTMB has indicated ongoing coordination with enforcement agencies and the deployment of auxiliary police patrols in identified hotspot areas. Physical hardening measures, including secured cable troughs and improved surveillance coverage, are being assessed to reduce the risk of recurrence.

For Malaysia’s electrified mainline corridors, the incident highlights the continuing exposure of below-rail assets in an operating environment where signalling, telecoms, and power systems are increasingly integrated. As traffic density rises and reliance on digital train control deepens, infrastructure protection will remain a core determinant of service reliability and lifecycle operating cost control.
