Scheduling System for MRT Train Frequencies, Conditions Triggering Injection of Additional Trains and Reviewing Commuter Feedback

Written Reply to Parliamentary Question

Mr Low Wu Yang Andre asked the Acting Minister for Transport

a.          whether MRT train frequencies currently operate on fixed timetables or dynamic schedules responsive to real-time demand;

b.          what specific thresholds of platform crowding, loading or other metrics trigger the injection of additional trains; and

c.           how frequently are these thresholds reviewed against actual commuter feedback.

Reply by Acting Minister for Transport Jeffrey Siow:

1.          Our MRT trains operate on fixed schedules, planned to meet anticipated passenger demand and maintain regular train arrival frequencies. The schedules are not typically adjusted during service hours, as any adjustment or train injection will disrupt the smooth flow of trains, especially during peak periods where the train arrival frequency is already high.

2.          The Land Transport Authority works with rail operators regularly to adjust train schedules in advance, based on demand and loading trends as well as commuter feedback. Operators are required to plan the schedules such that crowding is maintained below five passengers per square metre. In practice, they have ensured that the loading is kept well below this level, to alleviate platform crowding and avoid situations where passengers have difficulty boarding.
