Let the works begin: Construction of 30-km Thomson Line launched

It will be used by 400,000 commuters daily.

The LTA announced on Friday that construction has officially begun for the Thomson Line. The new rail line will connect the northern part of Singapore to the Central Business District (CBD) and Marina Bay area. 

According to the LTA, the 30-km line will have 22 stations and be fully underground. It is set to open in 2021 and is expected to carry 400,000 passengers daily.

“With connections to the North-South East-West Line (NSEWL), North East Line (NEL), Circle Line (CCL) and Downtown Line (DTL), the TSL will link communities in Woodlands, Sin Ming, Thomson and Kim Seng to the CBD and the rest of the island. When the line fully opens, it is projected to see a daily ridership of around 400,000 commuters,” the LTA announced.

Here’s more:

The TSL will bring significant time savings to commuters travelling along the north-south corridor.

For example, a resident from Springleaf travelling to Great World City will cut his or her journey time by half, as the direct train ride from Springleaf station to Great World station will take only 30 minutes, compared to an hour’s journey today by bus and MRT. 

Woodlands South residents travelling to Orchard will be able to do so within a 35-minute train ride on the TSL, compared to a 50-minute journey by bus and MRT today. 

With the interchanges, commuters will also have more alternate routes to different destinations across the rail network. 

For instance, Sin Ming residents working in Outram Park can now take TSL instead of having to travel by bus before transferring to NSEWL. With TSL, his or her journey will be reduced by at least 15 minutes from 45 minutes currently.

For the first time in Singapore’s rail history, Land Transport Authority’s (LTA) engineers will be using a new construction technology known as ground freezing at Marina Bay station to prevent water seepage during tunnelling works. 

At this site, a series of pipes will be inserted into the ground, before brine is introduced into the pipes, converting the surrounding ground water into strong, water-tight ice walls. 

In addition, tunnel construction process at Marina Bay will be even more complicated as the site involves a three-tunnel intersection of the TSL, North-South Line (NSL) and CCL.

A NOTE FROM SINGAPORE BUSINESS REVIEW

If you've been wondering whether SBR could work for your company — yes, probably.

A lot of the companies we partner with started as readers. They'd been following our coverage for a while, saw their own customers and competitors in it, and eventually asked the obvious question: could we do something with you? The answer is usually yes. The shape of it depends on what you're trying to do.


The options are broader than most people assume — thought leadership articles, sponsored content, industry summits across Southeast Asia, regional awards programmes, podcasts, and media placements in print and digital. Some partners use one channel; most use a mix. We figure out the right combination by starting with your brief, not with our rate card.


So if the question has been on your mind, here's the easy way to ask it.

We'll tell you honestly whether we can help, and how. It's a better use of everyone's time.
