Debated in Parliament on 8 Jan 2018.
Mr Melvin Yong Yik Chye asked the Minister for Transport (a) whether the extended engineering hours provided to SMRT as a result of the early closure and late opening of train services in December 2017 have benefited rail maintenance works; and (b) whether the Ministry will consider such early closure and late opening of train services on a more regular basis in 2018.
Last month, extended engineering hours through early closure and late opening of 19 Mass Rapid Transit (MRT) stations in the western sector of the North-South and East-West Lines were provided to the Singapore Mass Rapid Transit (SMRT). The adjustments in operating hours over four weekends, including two full Sunday closures, more than doubled the total number of engineering hours available between Friday nights and Monday mornings in December 2017, from 45 hours to 110 hours.
The extended engineering hours have been extremely useful for our engineering and maintenance teams. First, they have enabled the Land Transport Authority (LTA), SMRT and signalling system supplier Thales to accelerate the re-signalling of the East-West Line. Each weekend of extended engineering hours has allowed Thales to conduct the equivalent of five regular nights of site acceptance testing. Second, they have allowed SMRT to bring forward and intensify maintenance works and repairs of the running rails, station equipment and track circuits. They have also enabled LTA to conduct more maintenance inspections to ensure the quality of SMRT's maintenance works, especially those by outsourced contractors. Third, they have allowed LTA and SMRT to speed up the installation of noise barriers for the stretch between the Dover and Boon Lay MRT stations. On each weekend, the project team was able to make progress equivalent to four nights of normal engineering hours.
For these reasons, LTA and SMRT have announced similar plans for this month, involving the early closure and late opening of 10 East-West Line stations in the eastern sector over four weekends, including two full Sunday closures. Reduced train operating frequencies will also be in effect for seven North-South Line stations in the central area over the same period, as one track will be closed for maintenance.
Beyond January, we will extend engineering hours where possible so that we can complete the re-signalling of the East-West Line by the middle of the year. We are bringing forward the renewal of other critical systems on the North-South and East-West Lines, such as the power system and track circuits. We are also making plans to speed up the installation of noise barriers.
LTA will work closely with the Public Transport Operators to provide commuters affected by extended engineering hours with timely information and alternative transport arrangements. We are also working closely with the union to ensure that these plans are sustainable for our rail and bus workers. I would like to thank our public transport workers for their dedication, and seek commuters' continued understanding as we redouble efforts to improve train reliability.
