Data On Submission and Approval Rates of Maintenance Schedule Waiver Requests Submitted by Operators

Sectors

Trains

3 March 2026

Written Reply to Parliamentary Question

Assoc Prof Jamus Jerome Lim asked the Acting Minister for Transport

a.           since LTA began requiring operators to submit maintenance schedule waiver requests for review, how many have been submitted;

b.           how many were approved or rejected; and

c.           what criteria guide LTA's assessment of such requests.

Reply by Acting Minister for Transport Jeffrey Siow:

1.           Since 30 May 2025, the Land Transport Authority (LTA) has received and approved one request for an adjustment of scheduled maintenance from the rail operators. This was a one-month deferment of air-conditioning filter replacement for four Thomson-East Coast Line trains deployed for testing works.

2.           When assessing such requests, LTA takes into consideration the potential impact on safety and service reliability, the adequacy of mitigating measures put in place by the operator, and longer-term effects on asset performance.
