First announced on 15 August 2014, the line was formed by the merger of the planned Thomson Line (TSL) and Eastern Region Line (ERL). It will open in stages from Year 2019 to 2024.

In the Land Transport Master Plan 2040, a future extension, the Thomson-East Coast Line Extension, was mentioned. The extension will extend the line from the eastern Sungei Bedok terminus to Tanah Merah, via Changi Airport Terminal 5 and Expo. The existing Changi Branch Line of the East West Line, serving between Tanah Merah and Changi Airport via Expo will be converted to part of the Thomson-East Coast Line by around 2040.

The line will be served first by Mandai Depot, and East Coast Integrated Depot by Year 2024. Its rolling stock is the Kawasaki Heavy Industries & CSR Qingdao Sifang CT251, operating in a four-car formation, with a total of 91 trainsets ordered (364 vehicles).

Thomson stretch

The Thomson Line (TSL) was first announced on 25 January 2008 between Woodlands and Marina Bay, which would connect with to future Eastern Region Line extending to the East. In 2010, while architectural and engineering consultancy tenders were gradually released, the line had increased from 18 to 22 stations, and the length increased from 27 km to 30 km.

The TSL Depot (which would also house a bus depot) was built at Mandai on a 32 ha site and able to stable up to 90 trains, with construction beginning in end-2012. At Woodlands North, the terminus will connect with the Johor Bahru RTS Link. Construction of the TSL began in 2014 with all station working names confirmed as final names with the exception of Sin Ming station, which was changed to Bright Hill.

Woodlands, Caldecott, Stevens, Orchard, Outram Park and Marina Bay were planned as interchange stations with existing lines. Additionally, Tagore station (between Springleaf and Lentor) is built as a station box which would be furnished and opened in the future when the area is more developed.

East Coast stretch

Originally planned as the Eastern Region Line (ERL), it was first announced in 2001 as a 40 km oblong-shaped line looping around Jalan Besar and Expo. This northern section has since been integrated into the Downtown Line Stage 3 and the southern section was retained as the ERL, planned from Marina Bay to Sungei Bedok and interchanging with the Thomson Line.

The ERL Depot was to be an Integrated Depot in Changi which also houses the East-West Line and Downtown Line.


The Land Transport Authority (LTA) merged the Thomson and the Eastern Region lines to form the Thomson-East Coast Line (TEL) on 15 August 2014.

Construction of the TEL’s East Coast stretch (formerly the ERL) began in 2016 with all station working names confirmed as final names with the exception of Amber station, which was changed to Tanjong Katong.

Johor Bahru RTS Link

In December 2016, it was announced that the Rapid Transit System (RTS) link between Woodlands North and Bukit Chagar (Johor Bahru) will adopt Singapore’s Thomson-East Coast line system, including its signalling system, rolling stock, communication system and integrated supervisory control system, to reap economies of scale.

Operator Tender Award

A nine-year contract for the operation of the TEL was awarded to SMRT Trains Ltd on 15 September 2017, in a tender called in February 2017 and participated by SBS Transit and SMRT. In the two-envelope tender, SMRT Trains received a higher quality score. In particular, its proposal featured a commitment to invest heavily in predictive and reliability-centred maintenance to enhance reliability. SMRT Trains’ proposal also included a strong staff development plan, including customer-oriented training, and tailored community engagement initiatives. SMRT Trains also undertook a set of contractual guarantees in the form of service fee deductions should key obligations not be met. The total service fee over 9 years ($1.7 billion) quoted by SMRT Trains was also about 30% lower than that quoted by SBS Transit.

Additional Station – Founders’ Memorial

On 7 January 2019, LTA announced the that Founders’ Memorial MRT Station will be added to Stage 4 of the Thomson-East Coast Line, between Gardens by the Bay Station and Tanjong Rhu Station, scheduled for opening in 2025.
