Renewing oldest MRT lines to cost over $2.5b

A multi-year programme to renew the North-South and East-West MRT lines - Singapore's oldest and most heavily used - will cost more than $2.5 billion.


In the first phase, the rail sleepers, third rail and signalling system of the two lines, which opened more than 30 years ago, were replaced. The renewal programme began in 2013, and is expected to be completed by 2024.
Mr. Khaw said the power supply system renewal was 'the most complex of the three remaining projects', and was about 40% done. The renewed system will allow the two lines to accommodate more trains and, consequently, reduce train waiting time. Currently, 145 trains are deployed during the morning peak period at intervals of 120 seconds. When the renewal is completed, the intervals can be reduced to 100 seconds.


To speed up the renewal works, parts of the two lines have been subject to shorter operating hours on Fridays and weekends in recent years. This is expected to continue until the entire project is completed.
Meanwhile, 66 new trains are being built overseas by Bombardier, and should start arriving next year. The Canadian group won the supply contract worth $1.2 billion, which includes service support for the 30-year lifespan of the trains.
Mr. Khaw told transport workers present yesterday that 2019 was 'a good year', with the network clocking more than a million train-kilometres between delays in the first nine months - an 18-fold improvement over 2011's figure, and one matched by few other metros in the world. But he cautioned against complacency. "Today's success does not guarantee tomorrow's," said Mr. Khaw.
The upgrading of the North-South and East-West lines aside, Mr. Khaw said work to expand the rail network continues. He said government spending on new MRT lines 'will peak during the next two decades'. Announced projects include the Thomson-East Coast Line (the first phase of which will open later this month), the Jurong Region Line, the Circle Line extension and the Cross Island Line. When the Cross Island Line is completed by 2031, Singapore would have doubled its rail network to 360km. Observers reckon there will be at least two other new lines beyond 2031. The 2040 Land Transport Master Plan stated that a new line running parallel to the North-South Line is being studied.
