The new milestone comes as Singapore’s rail system continues its longest-ever streak without a major delay of more than 30 minutes since the statistic began being tracked in 2011.
According to the latest monthly rail reliability report released by the Land Transport Authority (LTA) on Friday, September 11, the MRT network’s Mean Kilometres Between Failures (MKBF) climbed to a record 2.88 million train-km in August, up sharply from 2.37 million train-km in July.
The figure surpassed the previous record of 2.627 million train-km set in June 2024.
Singapore MRT Reliability Hits New Record
The August result marked the fifth consecutive month in which Singapore’s mature MRT network recorded an MKBF of more than 2 million train-km.
MKBF is a key rail reliability measure that tracks the average distance a train travels before encountering a delay lasting more than five minutes. LTA calculates the figure using a 12-month moving average.
The latest result also extended another major milestone: Singapore’s mature MRT network went 10 consecutive months without a delay exceeding 30 minutes.
That is now the longest streak since LTA began tracking major rail delays in 2011.
LTA credited the improvement to the sustained efforts of transport workers and rail operators, as well as measures being implemented following recommendations from the Rail Reliability Taskforce.
Downtown Line Leads Major Improvements
All five mature MRT lines either improved or maintained their reliability performance in August.
The Downtown Line posted the most dramatic improvement, with its MKBF nearly doubling from 4.2 million train-km in July to 8.37 million train-km in August.
The latest figures showed:
- Downtown Line: 8.37 million train-km, up from 4.2 million
- North East Line: 4.48 million train-km, up slightly from 4.47 million
- Circle Line: 2.51 million train-km, up from 2.45 million
- East-West Line: 2.52 million train-km, up from 2.02 million
- North-South Line: 1.65 million train-km, unchanged from July
LTA said the Downtown and North East Lines continued to perform strongly over the past year.
The figures represent a remarkable turnaround from concerns surrounding Singapore’s rail network following a series of service disruptions in 2025.
From Rail Disruptions to Record Reliability
Singapore’s Rail Reliability Taskforce was formed in September 2025 after a series of disruptions across the MRT and LRT network.
The task force conducted technical audits and a wider review of rail operations, maintenance, asset management, workforce capabilities and service recovery procedures.
In February 2026, LTA, SMRT and SBS Transit announced that they would progressively implement the task force’s recommendations to strengthen the overall rail network.
The task force noted that Singapore’s rail reliability remained among the world’s strongest, but warned that maintaining performance would become increasingly challenging as parts of the network aged.
Some sections of Singapore’s MRT system are now more than four decades old, increasing the importance of maintenance, asset renewal and the integration of newer technologies.
The latest record suggests that the measures introduced so far are beginning to deliver results.
But Not Every Performance Indicator Improved
Despite the record MKBF figure, other rail performance indicators slipped slightly in August.
The MRT network’s Train Service Delivery rate fell to 99.62 per cent, compared with 99.71 per cent in July.
Train Service Delivery measures the actual distance travelled by trains against the scheduled distance.
Overall train punctuality also edged down from 99.29 per cent in July to 99.03 per cent in August.
Punctuality measures the percentage of train trips completed within two minutes of the scheduled time at the end of each line.
Lower punctuality does not necessarily mean a major disruption occurred. Operational issues affecting train frequencies can also lead to longer waiting times and increased crowding.
The figures highlight an important distinction: while trains are travelling longer distances between significant faults, day-to-day service regularity still requires close attention.
Thomson-East Coast Line Still Excluded From Overall Record
Singapore’s newest MRT line, the Thomson-East Coast Line (TEL), is not included in the overall MRT network reliability calculation because construction, extension and system integration works are still ongoing.
The TEL’s own MKBF improved from 373,000 train-km in July to 415,000 train-km in August.
LTA has previously said newer lines can experience operational issues linked to system updates and early-stage operations that differ from faults on more mature rail lines.
The authority expects the TEL’s reliability performance to improve after the line is fully opened and operations have stabilised.
A Major Win — But the Real Test Is Still Ahead
Singapore’s latest MRT reliability record represents a significant achievement for a rail network that faced intense scrutiny after multiple disruptions in 2025.
The jump to 2.88 million train-km between significant delays is well above Singapore’s long-standing target of 1 million train-km.
Earlier in 2026, the MRT network had already crossed the 2 million train-km mark for several consecutive months. The August result has now pushed that recovery to a new historic high.
But maintaining the record could prove harder than achieving it.
With ageing infrastructure, expanding rail lines and increasingly complex systems, Singapore’s transport authorities face the continuing challenge of keeping trains reliable while carrying out essential maintenance and renewal work.
For commuters, the biggest question is no longer whether Singapore’s MRT can hit a record.
It is whether the network can keep it.
