SINGAPORE – The MRT network registered a third consecutive month of gains in June, with the LRT network showing similar improvement.

On average, MRT trains clocked 2.5 million train-km between delays lasting more than five minutes between July 2025 and June 2026, Land Transport Authority (LTA) figures published on July 17 showed.

This marks the third time in a row that the figure has exceeded two million train-km since November 2024.

It is also above Singapore’s rail reliability target – measured by mean kilometres between failure (MKBF) – of one million train-km for the entire MRT network.

MKBF is a widely used engineering measure of rail reliability, and shows how far a train travels before it encounters a delay lasting more than five minutes. LTA’s figures are based on a 12-month moving average.

The SBS Transit-operated North East Line (NEL) and Downtown Line (DTL), as well as SMRT’s East-West Line (EWL), held steady in terms of reliability.

The reliability of the other two lines operated by SMRT – the North-South Line (NSL) and Circle Line (CCL) – rose.

NSL showed the bigger improvement, averaging 1.98 million train-km between delays, up from 1.65 million train-km in May. It, however, remained the least reliable of the five MRT lines.

As for the CCL, it averaged 2.4 million train-km between delays, up from 2.37 million train-km the previous month.

The NEL remained the most reliable MRT line, averaging 4.46 million train-km between delays.

In June, there was no major delay exceeding 30 minutes across the five MRT lines and LRT network, according to LTA’s report.
