Transport Minister Chee Hong Tat outlines the cause and ongoing upgrades for the Bukit Panjang LRT network.
Breakdown Details and Findings
On October 22, 2024, a gear failure in one of the Bukit Panjang LRT (BPLRT) train’s wheel assemblies caused a service disruption during peak hours, halting operations between Bukit Panjang and Choa Chu Kang stations. Transport Minister Chee Hong Tat revealed that friction from the faulty wheels deflated the tyres, triggering a power trip that damaged the power rail.
Efforts to retrieve the stalled train using a recovery vehicle failed due to traction power loss, resulting in an early end to services for repairs. Operations resumed the following morning.
Addressing Systemic Concerns
Responding to questions about potential systemic issues, Mr. Chee noted that the last similar incident occurred in 2010, and ongoing investigations have not yet identified broader problems.
BPLRT Upgrades in Progress
The 25-year-old BPLRT is undergoing a comprehensive renewal program to improve reliability. Recent updates include:
New Trains: Four of 19 third-generation vehicles are operational, with two under testing and the remainder expected by 2025.
Second-Generation Upgrades: Six out of 13 older vehicles have been modernized.
Improved Systems: Power supply and control systems have been enhanced, with upcoming replacements for power rails.
Dual-loop services have resumed on weekends and public holidays, with weekday services expected soon.
Passenger Concerns and Future Enhancements
MP Edward Chia raised concerns about peak-hour crowding, asking how upgrades will affect capacity and waiting times. Mr. Chee explained that improvements to signalling and additional trains could increase frequency, easing congestion.
The entire renewal program, slated for completion in 2026, aims to resolve legacy issues and deliver improved service.
MRT Reliability and Targets
Singapore’s MRT system continues to meet its reliability goals, with the mean kilometers between failure (MKBF) improving from 1.8 million train-km to almost two million by October. Discussions are underway to determine if the current MKBF target of one million train-km should be raised, balancing reliability with cost implications.
The Ministry of Transport remains committed to enhancing commuter experience while addressing ongoing challenges with legacy infrastructure.
