This dashboard shows the time series of service disruptions by rail line and length of delay.
Chart data excludes suicide attempts, maintenance/upgrading works and events that are beyond the control of the service operators e.g. power trip caused by lightning.
Under the licensing agreement between the Land Transport Authority (LTA) and the service operators, SMRT and SBS Transit are required to adhere to the Operating Performance Standards (OPS), which tracks the frequency of delays exceeding 30 minutes, among other key indicators. SMRT also classifies delays exceeding 1 hour as the most severe level of disruption (RED 1 and RED 2), which will trigger the Rail Incident Management Plan (RIMP). When the RIMP is activated, SMRT will deploy bus bridging services and additional staff to affected stations. In the case of a RED incident, the Police and the Singapore Civil Defense Force will also be activated (Committee of Inquiry report, para. 75, 348).
