Singapore MRT network marks longest streak of reliability since 2011

Singapore's Mass Rapid Transit (MRT) network has achieved a significant milestone, recording its longest period without major delays in nine months as of July. The Land Transport Authority (LTA) reported that no delays exceeding 30 minutes occurred across the network, excluding the Thomson-East Coast Line (TEL), which is still under construction.

This nine-month streak is the longest since the LTA began tracking this statistic in 2011. The LTA measures rail reliability using the Mean Kilometres Between Failures (MKBF) metric, which indicates the average distance a train travels before a delay of over five minutes occurs. In July, the overall MRT network's MKBF rose to 2,370,000 train-km, continuing a four-month trend of exceeding 2 million train-km.

Our high MKBF levels over the last four months reflect the sustained effort and dedication of our transport workers and rail operators to uplift reliability and improve their response to faults and incidents.

These figures also reflect the implementation of recommendations from the Rail Reliability Taskforce, with operators SMRT and SBS Transit working closely with the LTA.

The NSL MKBF for June 2026 has therefore been updated to 1.65 million train-km. The overall MRT network MKBF for Jun 2026 has also been updated to 2.36 million train-km.

All five established MRT lines either improved or maintained their MKBF figures in July. The Circle Line (CCL) saw an improvement, while the North East Line (NEL) also edged up. The North-South Line (NSL), East-West Line (EWL), and Downtown Line (DTL) maintained their previous MKBF figures. The LTA also revised its provisional June figures due to a delay on the NSL that exceeded five minutes after investigation.

While not included in the overall network figures, the TEL's MKBF also increased. The LTA noted that the newest line's MKBF is excluded due to ongoing construction, extension, and system integration works, acknowledging that teething issues are common during initial operations.
