Singapore’s train operator SMRT will invest S$900m ($724m) to upgrade its rail system in order to address problems that have led to several breakdowns in recent months.
Renovation works on SMRT’s ageing train network will be implemented in phases, starting from 2012 and running until 2019.
SMRT said that the investment for the renovation of the rail network will be co-funded by the Land Transport Authority (LTA).
The upgrading will include a complete overhaul of the signalling system on the north-south and east-west lines.
SMRT executive director and interim chief executive officer Tan Ek Kia said that the company has been working to address the causes of recent disruptions and upgrading the system to ensure reliable rail services.
"SMRT has plans for asset renewal in the coming years to ensure the system remains a safe and reliable one for commuters," Kia said.
"As the system ages, our maintenance regime needs to adapt from one that focuses on repair and overhaul, to one which also includes replacement and renewal."
The investment will also cover the purchase of new electronic signalling cards that help tackle the current signalling problems, as well as replacing all sleepers that secure tracks on the north-south and east-west lines.
SMRT said that it will replace all claws with fifth-generation models that come with a positive-locking system to better secure the third rail.
Under the project, each MRT line will be installed with a vibration monitoring system and a system to better detect wheel problems, which can help to identify vibration issues.
