SINGAPORE — Singapore’s MRT network has reached a new reliability milestone, recording its 10th consecutive month without a major delay lasting more than 30 minutes while achieving an all-time high in overall rail reliability in August.
The network, excluding the Thomson-East Coast Line (TEL), also maintained more than two million train-kilometres between failures for the fifth straight month.
The latest figures suggest a significant improvement for a rail system that faced a series of disruptions in 2025.
And after years of pressure to make Singapore’s trains more reliable, the latest report shows the network is now on its longest major disruption-free streak since the statistic began being tracked.
MRT Network Sets New Reliability Record
Singapore’s overall MRT network recorded a provisional Mean Kilometres Between Failure (MKBF) of 2.88 million train-km in August, up from 2.37 million train-km in July.
MKBF measures the average distance a train travels before encountering a delay of more than five minutes. A higher figure generally indicates better reliability.
The August performance marked the network’s fifth consecutive month above two million train-km.
All five mature MRT lines either maintained or improved their 12-month moving average:
- North-South Line (NSL)
- East-West Line (EWL)
- North-East Line (NEL)
- Circle Line (CCL)
- Downtown Line (DTL)
For commuters, the numbers point to a simple result: Singapore’s trains are travelling farther than ever before between service disruptions.
Downtown Line Posts Biggest Improvement
The Downtown Line recorded the strongest improvement among the mature MRT lines.
Its MKBF jumped from 4.2 million train-km in July to 8.37 million train-km in August.
The East-West Line also showed a notable improvement, rising from 2.02 million train-km to 2.52 million train-km.
The strong performance is particularly significant because Singapore’s rail network includes older infrastructure that requires continuous maintenance and upgrading.
Even the oldest North-South and East-West lines remained above the one-million train-km benchmark.
That means some of Singapore’s oldest rail lines are continuing to perform at a level considered highly reliable despite decades of operation.
10 Months Without a Major Delay
Perhaps the most striking figure in the August report is the continued absence of delays lasting more than 30 minutes.
August marked the 10th consecutive month without such a major disruption on the MRT network, excluding the TEL.
The previous nine-month streak recorded in July had already been described as the longest since the statistic began being tracked in 2011.
The latest result extends that record even further.
The milestone comes after Singapore experienced a series of rail disruptions between July and September 2025, prompting authorities and rail operators to launch a deeper review of the network.
Less than a year later, the MRT system is now reporting one of its strongest periods of reliability on record.
Train Service Delivery Remains Above 99%
Other rail performance indicators also remained strong in August.
Singapore’s overall MRT network recorded train service delivery of 99.62 per cent.
This metric measures the actual distance travelled by trains compared with the distance originally scheduled.
Train punctuality also remained above 99 per cent at 99.03 per cent.
Train punctuality measures how consistently train trips are completed on time.
The report showed that:
- The North-East Line improved in train service delivery
- The Circle Line improved in train service delivery
- The Circle Line also improved in punctuality
- Some other mature lines recorded slight declines in certain indicators
The overall figures, however, remained above 99 per cent.
In a network carrying millions of passenger journeys, even small percentage changes can represent a significant number of trains and commuters.
Thomson-East Coast Line Still Tracked Separately
The Thomson-East Coast Line is not included in the overall MRT network’s MKBF calculation.
Authorities said this is because the line is still undergoing construction, extension and system integration works alongside regular operations and maintenance.
TEL’s MKBF nevertheless improved from 373,000 train-km in July to 415,000 train-km in August.
The line continues to be monitored separately as work progresses on the remaining stages of its development.
Rail Reliability Taskforce Measures Take Effect
Authorities said the strong performance reflects sustained efforts by rail operators to improve reliability and strengthen their response to faults and incidents.
The latest results also follow recommendations made by the Rail Reliability Taskforce, which completed its review earlier this year.
The taskforce was formed after a series of rail disruptions in 2025 and examined areas including:
- Rail maintenance
- Asset management
- Power systems
- Workforce capabilities
- Service recovery
- Incident response
Authorities and rail operators are progressively implementing the recommendations across the network.
The measures include both immediate improvements and longer-term upgrades designed to strengthen the reliability of Singapore’s growing rail system.
The real test, however, will be whether the current record-breaking performance can be sustained as the network continues to age and expand.
Why Rail Reliability Matters to Singapore
Singapore’s MRT system is one of the country’s most important transport networks.
Any major disruption can affect commuters travelling to work, school, appointments and other destinations.
That makes reliability a major concern for both passengers and transport authorities.
Singapore has maintained an MRT network-wide target of at least one million train-km between failures since 2019.
The latest August figure of 2.88 million train-km places the network far above that benchmark.
But authorities have also acknowledged that maintaining high reliability becomes increasingly challenging as older rail infrastructure requires renewal and new technology must be integrated into the expanding system.
Can Singapore Keep the Record Going?
The latest report gives Singapore’s MRT network plenty to celebrate.
Ten months without a delay exceeding 30 minutes is a major achievement.
Five consecutive months above two million train-km between failures is another.
But rail reliability can change quickly.
A single major incident can affect statistics, commuters and public confidence.
With more upgrades, new lines and system integration work continuing, operators face the ongoing challenge of maintaining strong performance while preparing the network for the future.
The Bottom Line
Singapore’s MRT network has reached an all-time reliability high in August, extending its record streak without a major delay to 10 consecutive months.
The overall network recorded 2.88 million train-km between failures, up from 2.37 million in July and marking the fifth straight month above two million.
The Downtown Line delivered the biggest improvement, while train service delivery and punctuality across the network remained above 99 per cent.
But with Singapore’s rail system continuing to expand and older infrastructure requiring constant upgrades, the biggest question now is: Can the MRT keep this record-breaking reliability streak alive for an entire year?
