Platform configurations

The Downtown Line (DTL) which is currently under construction introduces a more varied platform configuration than is currently seen on the first four lines in operation (North-South, East-West, North East and Circle Lines) which typically feature island platforms (exception Dover, Braddell, Bishan). Island platforms are platforms that are located centrally between two parallel tracks. The Thomson Line (TSL) will mostly feature island platforms as well, with the exception at 4 stations.

These stations are Napier, Maxwell, Shenton Way and Marina Bay which will be stacked stations where the running tunnels are directly on top of each other instead of side-by-side as in island platform stations. As such, the platforms will be located on one side of the train as well. Here's an image of the tunnel set up at Marina Bay station.

Contract awards - T202 & T217

Yesterday the Land Transport Authority announced the final civil contract awards for the Thomson Line (TSL) due this year - contracts T202 and T217. Contract T202 is for the construction of Woodlands North station with over-run tracks and bored tunnels to Woodlands interchange. There will be a scissors crossover before the station as well. This contract was awarded to Penta-Ocean Construction Ltd who is currently building Bendemeer station on Downtown Line 3 (DTL3).

The interior of Woodlands North is spacious, with lots of escalators to cater for crowds accessing the JB RTS system.

Contract T217 is for the in-house designed Napier station at the junction of Napier and Cluny Roads. This contract involves construction of the stacked side station with two entrances and stacked bored tunnels to Orchard Boulevard station. Sinohydro Co has received the award and this will be the first time they are involved in an MRT project here in Singapore. Their previous track record lies in Guangzhou and Tianjin in China.

Outram Park station pre-construction

Outram Park has changed over the last 20-odd years since the first works for the MRT in Singapore began. In the 80's, work began on construction for the original network with the East-West Line (EWL) being built. In the 90's, work on the North-East Line (NEL) commenced. The decade of the 2000s saw the area being given a break from all rail construction work. Now in the 2010's, the Thomson Line (TSL) is set to open up the area once again as the Outram Park interchange is built. Along with the TSL station, major modification works to the existing EWL and NEL stations will be done, including extensive re-configuration of the transfer linkways. Here are some photos before any works commence on the site.

About this blog

Hi there,

This is a blog set up to track the construction progress of Singapore's Thomson MRT Line (TSL) stage 1 and stage 2. Currently, we're in the process of testing out the layouts and whether this is a workable platform for sorting the information accordingly. Do stick around and see how the landscape changes over the years. We'd welcome photos too, just drop a line via the comments section.

For now though, follow us as we test the layout on the Downtown Line construction blog. Let us know what works and what doesn't. Thanks & stay tuned for more here as construction work ramps up on TSL!
