Thomson-East Coast MRT Line is a mass rapid transit line of the Singapore MRT. The sixth MRT line in Singapore, it is created through the merger of the planned Thomson-East Coast MRT Line and Eastern Region Line. The line will be fully underground, and will have 32 stations over a distance of 43 kilometers (27 miles). The line will be one of the world's longest driverless rapid transit lines.
The Thomson-East Coast Line will be a fully automatic, driverless system. The line starts in Woodlands North and ends at Sungei Bedok. Along the way it will pass through Woodlands, Sin Ming, Orchard, Outram and the Downtown Core.
The first stage of the Thomson-East Coast Line, between Woodlands North MRT Station and Woodlands South MRT Station, opened to commuters on 31 January 2020. The second stage, between Springleaf MRT Station and Caldecott MRT Station, opened on 28 August 2021, while the third stage, between Caldecott MRT Station and Gardens by the Bay MRT Station, is opened on 13 November 2022. The line is presently colour coded brown, but may be changed later. Each station on the Thomson-East Coast MRT Line carries the letter "TS" followed by the Station Number.
Planning for the Thomson-East Coast Line goes back to its initial announcement on 25 January, 2008. Construction work on the line began in January 2014, with a groundbreaking ceremony conducted in Woodlands on 27 June, 2014. There are just three stations in Stage 1, namely the Woodlands North MRT Station, the existing Woodlands MRT Station and Woodlands South MRT Station. The Woodlands MRT Station will serve as an interchange for the Thomson-East Coast Line with the North-South Line.
At time of this update (July 2022), stations in Stage 3 are under construction.
