JUNE FIGURES REVISED
LTA also revised its provisional June reliability figures to account for a delay on the NSL on Jun 11, which was found to have exceeded 5 minutes following the conclusion of investigations.
"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," said LTA.
"As stated within the report, reported figures are subject to adjustment pending ongoing incident investigations."
TEL's MKBF, though not included in the overall MKBF, rose to 373,000 train-km from 355,000 train-km last month.
The MKBF of Singapore's newest MRT line is not included in the overall MRT network's MKBF because it is still undergoing construction, extension and system integration works while in regular operation.
"Such teething issues that arise during initial operations and as a result of system updates can result in delays, even though the nature of such delays are different from those encountered during the operation of mature lines," said LTA.
TRAIN SERVICE DELIVERY AND PUNCTUALITY
LTA also uses other metrics to measure rail reliability, including train service delivery, which measures whether trains operated according to schedule.
It is calculated by measuring the actual distance travelled by trains compared to the scheduled distance, and expressed as a percentage.
