MRT network reliability in April hits highest level since November 2024

Reliability either held steady or improved across all lines except the Circle Line

The reliability of the MRT network in April was the highest since November 2024, based on figures released by the Land Transport Authority (LTA) on May 15.

On average, trains clocked 2.22 million train-km between delays lasting more than five minutes between May 2025 and April 2026.

This was the first time the figure had exceeded 2 million train-km since November 2024, LTA said. As at the end of November 2024, it was 2.2 million train-km.

The network remained above Singapore’s rail reliability target — measured by mean kilometres between failure (MKBF) - of 1 million train-km.

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

Reliability either held steady or improved across all lines except the Circle Line (CCL), which recorded a dip in April.

The SBS Transit-operated North East Line (NEL) remained the most reliable, holding steady at 4.45 million train-km between delays, recording the same figure in March.

SBS Transit’s Downtown Line (DTL) came in second, averaging 4.2 million train-km between delays, doubling from 2.1 million train-km in March.

The SMRT-operated CCL followed, at 2.36 million train-km, a dip from 2.37 million train-km.
