Oversight of Deviations Made by Rail Operators from Train Manufacturer's Recommended Maintenance Schedule

101 Mr Gerald Giam Yean Song asked the Acting Minister for Transport (a) what regulations are rail operators subjected to when they deviate from a train manufacturer's recommended train maintenance schedule; and (b) whether the Ministry will review SMRT's waiver approval system after the Transport Safety Investigation Bureau (TSIB) report of 31 May 2025 has found that waivers are granted without proper engineering justification or meticulous documentation.

Mr Jeffrey Siow: This question has been addressed in the written reply issued for Parliamentary Question No 58 for written answer for the 24 September 2025 Parliament Sitting.
