MTR Lam Tin Station Fire: Two Incidents Linked to Insulator Failure, Cable Overheating
HK01 · 4 SOURCES1 day ago2 MIN
Summary
The MTR Lam Tin Station on the Kwun Tong Line experienced two separate fire incidents within 15 hours on October 13-14, both traced to electrical system failures. Preliminary investigations revealed that an insulator rubber failure caused a short circuit and fire on tracks, while cable overheating in an equipment room the following day resulted from degraded grounding connections under abnormal operating conditions. The Transport and Logistics Bureau and MTR submitted investigation documents to the Legislative Council on October 27, with authorities demanding a detailed report and improvement measures within one month.
Key Points
- Two fire incidents occurred at Lam Tin Station on October 13 and 14, less than 15 hours apart, both during evening and morning peak hours
- The first incident on October 13 evening involved an insulator rubber failure at turnout components near the station, causing a short circuit that produced sparks and fire
- The second incident on October 14 morning occurred in an equipment room where a portable grounding switch remained closed due to the previous day's incident, accelerating degradation of a grounding bus connection and causing cable overheating and smoke
- MTR has inspected all similar insulator rubber across all lines and found no abnormalities, and is studying the introduction of IoT sensors for continuous monitoring
- Both incidents triggered the Service Performance Rebate mechanism, requiring MTR to contribute funds for peak-hour delays exceeding 31 minutes, with half-price Special Fare Days when the account reaches HK$25 million
Why It Matters
The consecutive incidents at Lam Tin Station expose potential vulnerabilities in MTR's electrical infrastructure, prompting government intervention and EMSD investigation, while the Service Performance Rebate mechanism ensures accountability through passenger compensation. MTR must offer half-price fare concessions for both incidents once the rebate account accumulates sufficient funds .
