Singapore’s Mass Rapid Transit system, or MRT, earned praise for years as a top example of smooth and dependable public transport. Riders trusted it to move millions across the city-state without much hassle. But now, that image has faded. The system struggles with a repeated pattern of breakdowns and fixes.
In September 2025, the government set up a new task force. This came right after 15 major disruptions hit in only three months. These events left commuters stranded, delayed trains, and sparked widespread anger. The task force aims to tackle urgent fixes. Yet it also highlights a deeper issue. Despite huge spending—billions of dollars poured in over the last 15 years—and wave after wave of changes, the MRT still fails to stay reliable for good.
This report looks closely at the root causes behind these ongoing problems. It covers structural flaws, like aging tracks and worn-out parts that wear down faster than expected. Operational issues play a big role too, such as poor maintenance schedules that lead to sudden failures during peak hours. Institutional factors add to the mess, including coordination gaps between agencies that slow down responses.
To understand this, consider past events. In 2015, a major signaling fault halted the North-South Line for hours, affecting over 200,000 people. The government then launched reforms, like better training for staff and new safety checks. Some changes helped short-term. Train breakdowns dropped by about 20% in the years that followed, based on official reports. But gains didn’t last. By 2023, disruptions climbed again, with floods and power issues exposing weak spots in the network.
These mixed results show why simple patches don’t cut it. The MRT has grown a lot since the 1980s, when it first opened with just a few lines. Today, it spans over 200 kilometers, serving a denser population and linking to buses and other modes. This expansion brings new headaches, like integrating old and new tech without full harmony.
Experts point out that rapid urban growth in Singapore amps up the pressure. One transport analyst noted in a recent interview, “The system worked well in quieter times, but now it faces constant strain from more riders and bigger demands.” Readers might wonder: why hasn’t all that money solved this? The answer lies in how reforms often focus on quick wins, not long-term overhauls. For instance, after the 2017 Joo Koon collision that injured dozens, rules tightened on software updates. Still, human errors and supply chain delays for parts keep popping up.
This section weighs those past efforts against today’s reality. It spots key hurdles in the network’s shift to handle electric buses and future smart tech. By breaking down these layers, the analysis aims to guide better steps forward, ensuring the MRT can once again live up to its early promise.
The Current Crisis: More Than Just Numbers
The Immediate Trigger
The latest round of disruptions began in earnest during September 2025, with three major incidents occurring over just four days. These weren’t isolated technical glitches but significant service interruptions that affected thousands of commuters during peak hours. The September 17 disruption on the Thomson-East Coast Line (TEL) at Outram Park station exemplified the ripple effects—passengers stranded on platforms, emergency shuttle services deployed, and the familiar sight of frustrated commuters adapting their daily routines around an unreliable system.
Beyond the Statistics
While rail operators and authorities often cite technical metrics showing performance above the “one delay per million kilometers” threshold, there’s a growing disconnect between these paper statistics and lived passenger experience. This gap reflects a fundamental measurement problem: official reliability metrics may not capture the full scope of service degradation that passengers experience, including shorter delays, overcrowding due to reduced service frequency, and the cumulative stress of system unpredictability.
The psychological impact on commuters cannot be understated. In a city-state where public transport ridership exceeds 3 million daily trips, even minor disruptions create exponential effects on productivity, quality of life, and public trust in essential infrastructure.
Historical Context: A Pattern of Crisis and Reform
The 2011 Watershed Moment
Singapore’s rail reliability challenges first gained widespread public attention in 2011, marking a turning point that would define the next decade and a half of transport policy. The year was punctuated by multiple breakdowns, culminating in two North-South Line disruptions that occurred within days of each other—an unprecedented failure that shook public confidence and prompted then-Prime Minister Lee Hsien Loong to convene a Committee of Inquiry.
The inquiry’s findings were damning, identifying cultural and systemic issues within SMRT Corporation and revealing maintenance practices that had prioritized cost-cutting over system integrity. The response was comprehensive: profuse public apologies, management changes, and a detailed roadmap for transformation that would cost billions and take over a decade to implement.
The Great Renewal: 2012-2019
The period following the 2011 crisis saw the most ambitious infrastructure renewal program in Singapore’s history. The $2.6 billion upgrade of the North-South and East-West lines—the system’s oldest and most heavily used corridors—involved replacing six core systems including signaling, power supply, and the entire fleet of trains.
This wasn’t merely a technical exercise but a comprehensive reimagining of how Singapore’s rail system should operate. SMRT expanded its customer service team from 190 to 700 personnel, implemented new crowd control protocols, and invested heavily in preventive maintenance technologies designed to identify potential failures before they occurred.
The results were initially promising. Rail reliability improved threefold between 2015 and 2017, and by 2019, Singapore had achieved its ambitious target of limiting delays to once per million kilometers of operation. This performance put the city-state on par with Taipei Metro, widely considered the gold standard for urban rail reliability.
The False Dawn: Why Success Didn’t Last
However, the apparent triumph of Singapore’s rail transformation proved ephemeral. Despite the massive investments and systematic reforms, new reliability challenges emerged almost as soon as the old ones were resolved. The September 2024 East-West Line disruption, which crippled service for six days and affected millions of passengers, demonstrated that fundamental vulnerabilities remained embedded within the system.
Between July 2024 and June 2025, overall MRT network reliability dropped to its lowest level since 2020, even as individual line performances continued to meet technical targets. This paradox highlights a critical issue: the complexity of measuring and maintaining reliability across an increasingly interconnected and sophisticated transit network.
The Evolving Challenge: Why Today’s Problems Are Different
Scale and Complexity
The Singapore of 2025 operates a fundamentally different rail network than the one that experienced the 2011 crisis. The system has expanded from 175 kilometers to 271 kilometers between 2011 and 2024, incorporating new lines, stations, and technologies that create exponentially more complex operational requirements.
This expansion isn’t merely additive—it’s transformational. Each new line introduces different technical standards, operational procedures, and integration challenges. The Thomson-East Coast Line, Downtown Line, and Circle Line each employ distinct signaling systems, train technologies, and maintenance protocols that must seamlessly interact with the older North-South and East-West infrastructure.
The mathematical reality is stark: more kilometers of track, more stations, more trains, and more electronic systems create exponentially more potential failure points. A network with twice the physical infrastructure doesn’t simply double the maintenance requirements—it can quadruple or quintuple the complexity of ensuring system-wide reliability.
Institutional Evolution and Responsibility Diffusion
Perhaps more significantly, the institutional landscape governing Singapore’s rail system has evolved dramatically since 2011. The Land Transport Authority has transitioned from primarily a regulatory role to becoming the owner of all rail assets, making critical decisions about procurement, maintenance standards, and system integration.
This shift creates both opportunities and challenges. Asset ownership allows for more coordinated long-term planning and investment, but it also diffuses accountability in ways that may complicate rapid problem-solving. When failures occur, determining responsibility between LTA as asset owner, operators as service providers, and various contractors and consultants becomes increasingly complex.
The traditional model of holding rail operators solely accountable for reliability may no longer be sufficient when critical decisions about infrastructure investment, technology selection, and maintenance protocols are made at the authority level.
Technology Integration Challenges
Modern rail systems rely on increasingly sophisticated technology integration that creates new categories of potential failure. The interaction between legacy systems upgraded over multiple phases and new technologies deployed across different time periods creates compatibility challenges that didn’t exist in simpler, more homogeneous networks.
Singapore’s rail system now incorporates multiple generations of signaling technology, various train control systems, and diverse maintenance protocols that must work together seamlessly. The failure of any one component can cascade through interconnected systems in ways that are difficult to predict or prevent.
International Perspectives: Learning from Global Experience
The Taipei Metro Model
Singapore’s aspiration to match Taipei Metro’s reliability provides an instructive comparison. Taipei’s success stems from several factors that may not be easily replicable: a more geologically stable environment, a later start that allowed incorporation of more modern technology from the outset, and a different approach to system expansion that prioritized consolidation over rapid growth.
Significantly, while Singapore’s reliability declined between 2019 and 2025, Taipei Metro’s performance continued improving, suggesting that achieving initial reliability targets is different from maintaining them over time as systems age and expand.
London’s Mixed Experience
London’s experience with rail reliability offers both cautionary tales and potential solutions. Transport for London has struggled with similar challenges of maintaining service quality across an aging, complex network while simultaneously expanding capacity and modernizing infrastructure. Their approach has increasingly emphasized predictive maintenance, passenger communication, and service recovery protocols that minimize disruption impact even when technical failures occur.
Tokyo’s Systematic Approach
Tokyo’s rail networks, operating at scales and complexities that dwarf Singapore’s system, maintain exceptional reliability through systematic approaches to maintenance, rigorous staff training, and cultural emphasis on continuous improvement. However, Tokyo’s model relies on operational practices and workforce characteristics that may not translate directly to Singapore’s context.
The New Task Force: Prospects and Limitations
Mandate and Structure
The newly formed task force brings together technical specialists with senior leaders from rail operators and LTA, suggesting recognition that previous approaches may have been too narrowly focused on either technical solutions or management reforms without sufficient integration between the two.
The task force’s mandate includes three key areas: identifying components requiring more frequent replacement or upgrade, conducting comprehensive technical audits of critical systems, and reviewing service recovery processes to minimize passenger impact during future disruptions.
Learning from Past Interventions
The most successful previous intervention was arguably the appointment of veteran public servant Tan Gee Paw as rail transformation adviser in 2015. Tan’s outside perspective as a water engineer brought fresh analytical approaches that identified problems invisible to transportation specialists working within conventional frameworks.
Tan’s emphasis on “street-smart, sharp-eyed engineers”—his “rat catchers”—who could identify risks beyond standard codes of practice proved crucial to temporary improvements in reliability. His warning against over-reliance on third-party consultants who “use the same codes of practice and design practices” remains relevant to current challenges.
Financial Resources and Constraints
The task force benefits from substantial financial backing, with $1 billion committed over five years for asset management improvements and workforce capability enhancement. This represents significant investment, but it builds upon the billions already spent on previous reform efforts with mixed long-term results.
The challenge isn’t financial constraints but rather ensuring that new investments address root causes rather than symptoms. Previous spending focused heavily on hardware replacement and technology upgrades, with less attention to operational culture, institutional coordination, and long-term system resilience.
Structural Challenges Requiring Systematic Solutions
Measurement and Accountability
Current reliability metrics may be inadequate for capturing the full scope of system performance from a passenger perspective. The focus on “delays of five minutes or more” misses shorter disruptions that still significantly impact commuter experience, particularly during peak hours when schedule adherence is critical.
A more comprehensive measurement framework might incorporate passenger satisfaction indicators, system resilience metrics, and operational flexibility measures that better reflect the true health of the transit network.
Workforce and Culture
Rail reliability ultimately depends on human decision-making at multiple levels: maintenance technicians identifying potential problems, control room operators managing disruptions, and senior managers allocating resources and setting priorities. Previous reform efforts have focused heavily on technology and procedures while giving less attention to workforce culture and capabilities.
Singapore’s tight labor market and competition for engineering talent creates ongoing challenges in building and maintaining the specialized expertise required for complex rail operations. The expansion of the network has increased workforce requirements just as demographic trends and economic diversification create alternative career opportunities for skilled technical workers.
Integration and Coordination
The current institutional structure, with LTA as asset owner and multiple operators as service providers, requires unprecedented levels of coordination to maintain system-wide reliability. Traditional approaches that worked when operators had end-to-end responsibility for smaller, simpler networks may be insufficient for today’s complex, interconnected system.
Effective coordination requires not just formal protocols but also informal relationships, shared culture, and aligned incentives across organizations with different missions, constraints, and performance measures.
Recommendations for Breaking the Cycle
Adaptive Management Approaches
Rather than seeking permanent solutions through one-time interventions, Singapore should consider adaptive management approaches that assume ongoing challenges and build systematic capabilities for continuous improvement. This might include regular independent assessments, rotating external advisers, and institutionalized processes for incorporating lessons learned from international experience.
Passenger-Centric Reliability Metrics
Developing more sophisticated reliability measures that reflect passenger experience could help align technical performance with service quality. This might include metrics for journey predictability, information quality during disruptions, and recovery time effectiveness.
Long-term System Architecture
Singapore should consider whether its current approach to network expansion and integration creates inherent reliability challenges that cannot be solved through operational improvements alone. This might require fundamental decisions about technology standardization, service patterns, and the appropriate balance between system capacity and system resilience.
Regional Integration and Learning
Singapore’s small scale provides both advantages and disadvantages in addressing rail reliability challenges. Systematic engagement with other advanced transit systems through formal partnerships, staff exchanges, and joint research initiatives could provide ongoing sources of innovation and fresh perspectives.
Conclusion: The Path Forward
Singapore’s rail reliability challenges reflect the broader complexities of maintaining advanced urban infrastructure in a rapidly evolving technological and institutional environment. The formation of another task force represents both acknowledgment of ongoing problems and commitment to finding solutions, but success will require moving beyond the “familiar playbook” that has produced mixed results over the past decade and a half.
The ultimate test will be whether Singapore can develop systematic capabilities for maintaining reliability as a ongoing process rather than treating it as a problem to be solved once and for all. This requires not just technical excellence but also institutional adaptability, cultural commitment to continuous improvement, and realistic acknowledgment of the inherent challenges in operating complex systems at scale.
The stakes extend beyond transportation efficiency to encompass broader questions about Singapore’s capacity to maintain the high-quality infrastructure that underpins its economic competitiveness and quality of life. Success in addressing rail reliability challenges could provide a model for tackling similar infrastructure challenges in other sectors, while failure risks undermining public confidence in the government’s ability to manage essential services effectively.
The next few months will reveal whether the latest reform effort can break the cycle of recurring crises or whether Singapore needs to fundamentally reconsider its approach to rail system management and governance. The answer will have implications far beyond the daily commute experience of individual passengers, touching on fundamental questions about infrastructure resilience, institutional effectiveness, and urban sustainability in one of the world’s most advanced city-states.
