Addressing Deteriorating MRT Reliability and Measures to Address Root Causes

Mr Yip Hon Weng asked the Acting Minister for Transport (a) why has MRT reliability fallen to its lowest levels since 2020 with even newer lines showing significant declines; (b) what proportion of breakdowns are due to under-maintenance and poor equipment quality; (c) how effective are the upgraded signalling systems; and (d) what measures are being taken to address the root causes.

This question has been addressed in the oral reply to Parliamentary Questions 19 to 24 at the 22 September 2025 Parliament sitting. [Please refer to ​"Causes for Recent MRT and LRT Breakdowns, and Measures to Improve Rail Reliability and Review Financial Penalties", Official Report, 22 September 2025, Vol 96, Issue 2, Oral Answers to Questions section.]
