Extended engineering hours on Sengkang-Punggol Light Rail Transit on Saturdays and Sundays

SBS Transit will be conducting maintenance works on certain sections of the Sengkang-Punggol Light Rail Transit (SPLRT) network on 13 weekends during passenger service hours, from 5 December 2020 to 7 March 2021, excluding the Chinese New Year Holiday weekend on 13 and 14 February 2021.

The viaduct of the LRT comprises sections that are connected using fixtures called finger-joints.  Due to the constant movements of Light Rail Vehicles (LRVs) running over them, finger-joints will deteriorate over time and cause bumpy journeys. During the maintenance works, some of the finger-joints of the concrete plinths along the guideways will be repaired ahead of further wear and tear to ensure continued reliability of LRT services. It will involve hacking away the ends of the concrete plinths, re-installing reinforcement bars and repositioning the finger-joints before cementing them into place again. These repair works will ensure that commuters’ journeys continue to be smooth and comfortable.  Concurrently, maintenance works will also be carried out on the switch machines, which are located on sections of the guideways to enable LRVs to switch tracks.

The extended engineering hours during these 13 weekends will allow hacking works to be conducted during the day to minimise disturbance to residents at night and cater time for the concrete to be cured before it is safe for the LRVs to run on the plinths. During this period, train services will continue to operate as usual from one platform while the other will be closed for works. 

To minimise inconvenience to residents on the affected weekends, temporary sound barriers will be put up in the work areas and customer service officers will be deployed to the stations to offer assistance to commuters. Publicity posters will be put up at LRT stations to keep commuters informed of the maintenance works carried out. Commuters will also be informed via announcements on the LRT platforms and alerts on SBS Transit’s social media pages. Please refer to the attached posters for details.
