Shortened Operating Hours for Rail Renewal Work

Shorter operating hours along selected stretches of the East West Line (EWL), North South Line (NSL), Sengkang LRT (SKLRT), Punggol LRT (PGLRT) and Bukit Panjang LRT (BPLRT) take effect on selected weekends to facilitate additional engineering hours for re-signalling and maintenance work. This will involve early closures, late openings, and full-day closures.

These closures allow more time for rail maintenance and renewal works to be carried out. These shorter operating hours became prevalent in the wake of the Joo Koon train collision incident in November 2017, to speed up re-signalling works as well as for other purposes.

Early Closures started in 2014 to facilitate SMRT’s rail renewal works, including the replacement of timber sleepers with concrete sleepers, third rail replacement and resignalling.


Additional Engineering Hours

East West Line

The shortened operating hours facilitate additional engineering hours for re-signalling and maintenance work. Beyond April 2018, these additional engineering hours will be used to facilitate replacement of power supply and track circuits.

North South Line

The shortened operating hours facilitate additional engineering hours for intensive railway maintenance and improvement works. These works include replacement of power supply and track circuits in the later half of 2018.

Sengkang & Punggol LRT

The shortened operating hours facilitate replacement works conducted on the finger joints of concrete plinths, enhanced preventive maintenance on the signalling cables, as well as the asset renewal works which include replacement of the power rail and power rail assemblies.

Bukit Panjang LRT

The full day closures allow more time for maintenance works, such as the replacement of sections of the power rails, track switch components as well as the parts of the doors and propulsion systems of LRT trains as part of the Bukit Panjang LRT Overhaul programme.

Downtown Line

Late Openings on Sundays in 2017 facilitated more time for testing of the entire Downtown Line as an integrated line in preparation for the opening of Downtown Line Stage 3 from Fort Canning to Expo on 21 October 2017.
