MRT reliability nears record high as Circle Line performance improves by 50%

Singapore's Mass Rapid Transit (MRT) network demonstrated near-record reliability in May, with the Circle Line (CCL) experiencing a significant 50% improvement in performance.

The Land Transport Authority (LTA) released its monthly report on Friday, June 12, detailing the network's operational statistics. The LTA measures reliability using a 12-month moving average of Mean Kilometres Between Failures (MKBF), which tracks the average distance a train travels before experiencing a delay of over five minutes.

In May, the overall MRT network's MKBF reached 2,500,000 train-kilometers, an increase from 2,220,000 train-km in April. This marks the second consecutive month the network's MKBF has surpassed 2,000,000 train-km. The figure, however, remained slightly below the record high of 2,627,000 train-km achieved in June 2024.

The Circle Line's performance was a key contributor to May's strong figures, with its MKBF rising to 3,550,000 train-km from 2,360,000 train-km in April. The LTA described this increase as "significant." Other lines, including the East-West Line and Downtown Line, maintained their MKBF from April. The North-South Line saw a modest gain, while the North-East Line experienced a slight increase. Notably, no MRT delays exceeding 30 minutes were recorded in May.
