The Land Transport Authority has awarded Japanese technology firm Meiden Singapore two deals to upgrade and renew the MRT power supply system on the North-South and East-West lines.
The announcement by LTA was made on Friday (9 Feb), with 2 deals worth a combined $500 million.
A third contract worth $73 million was made with German industrial firm Siemens and French firm ENGIE Services Singapore, for the replacement of track circuit systems.
LTA stated that the new power supply system would “significantly reduce” the number of power-related faults.
The new system would allow automatic switching to another power supply source during power outages.
It is also equipped with a fault identification system to isolate power faults, which would speed up service recovery.
The power capacity at three stations, Yasin, Bishan and Stamford, will also be increased, which would allow a higher number of trains on the EW and NS lines at any point of time.
A new track circuit system will also be implemented, which, LTA said will be able to “detect the location of trains on the line and facilitate speedier recovery from a signaling system failure“.
It would be able to “detect the presence of broken rails that require repair, as well as use its built-in condition monitoring system to pre-emptively address possible track circuit failures before they occur.”
The power supply system and track circuit system are 2 of 6 core systems that allow the MRT to work on a day to day basis.
The contracted firms are slated to begin work later this year, and are expected to complete the work by the early 2020s.
Hopefully, the occurrence of train delays and faults would be completely eliminated, or at least significantly reduced, soon.
