While the MKBF is a simple and internationally recognised indicator of reliability, it has its limitations. For example, it does not reflect the duration of disruptions, and therefore the actual impact on commuters. To address this, LTA also publishes the number of delays lasting over 30 minutes in its Rail Reliability Report, to show the frequency of more severe disruptions. LTA intends to share additional indicators publicly, such as the proportion of scheduled mileage travelled by revenue trains, and the punctuality of trains reaching terminus stations. LTA is also studying additional metrics that better reflect the impact of disruptions on commuters. This could include the number of affected commuter trips, considering disruption extent and duration. These new indicators will be included in the monthly rail reliability reports when ready.
