Downtown Line

The Downtown Line is the fifth line to be introduced into the MRT system and is coloured blue on the system map. SBS Transit is currently operating this line.

Designed as a medium capacity radial line, the Downtown Line boasts as the longest fully underground and automated rapid transit line in the world. Spanning 41.9km with 34 stations from the northwest to the eastern part of Singapore, the line opens up rail connections in Bukit Timah and provides an alternative to the East-West Line.

The line opened in three stages in 2013, 2015 and 2017, with a 2.2km extension from Expo that will be completed by 2024.

As with newer train lines, the stations feature curated artworks as part of the Art in Transit programme. The artworks for Beauty World, Jalan Besar and Expo stations are selected through the Downtown Line Art in Transit competition.

Initial plans

The Downtown Line 1 was originally announced on 14 June 2005 as a 3.4km Circle Line extension from Promenade to Chinatown stations.

Stage 2 of the Downtown Line (then Bukit Timah Line) was designed as a 20km connection from the Bukit Timah corridor to the downtown.

Stage 3 of the Downtown Line was part of the northern section of the original 40km rectangular Eastern Region Line. It was then later announced to link all three sections, forming the three stages of the Downtown Line, including a 0.9km revision to connect Bugis station from Promenade.

Downtown Line 1

Constructions for the 4.3km Downtown Line 1 started on 12 February 2008 and consists of six stations from Bugis to Chinatown. The first phase of the line opened on 22 December 2013, allowing commuters to conveniently travel within the city area.

As the DTL1 is isolated from Gali Batu Depot, the temporary Marina Bay Maintenance Facility next to Marina Bay station will provide simple maintenance to the rolling stock before the opening of DTL2.

Downtown Line 2

Constructions for the 12-station 15.3km Downtown Line 2 and 1.3km track to Gali Batu Depot started on 3 July 2009. The line was initially delayed by a year due to insolvency issues, but the opening was then pushed forward to 2015.

The line opened on 27 December 2015, connecting Bukit Panjang to Bugis, passing through Beauty World, Botanic Gardens, Newton and Little India. Commuters travelling to and from the Bukit Timah area will benefit from the DTL2.

Downtown Line 3

The 21km Downtown Line 3 started constructions on 28 November 2011 and comprises of 16 stations from Chinatown to Expo.

Connecting the eastern corridor and intersecting with the Circle Line and East-West Line at MacPherson, Tampines and Expo stations, the DTL3 commenced service on 21 October 2017.

Line Extensions

Downtown Line 3 Extension

A 2-station 2.2km extension from the Downtown Line 3 Expo station will connect to the Thomson-East Coast Line Sungei Bedok station and the East Coast Integrated Depot. Constructions began on 21 July 2016, together with the East Coast stretch of the Thomson-East Coast Line and the depot.

The extension is expected to be completed by 2024.

Hume Station

The new station is situated between Hillview and Beauty World and will be the first underground station to be added along an existing line. As the station box has been constructed during the construction of the Downtown Line Stage 2, the station will only be required to be refitted.

Construction works for the new station began on 28 February 2021 and the new station is expected to be completed by 2025.

Downtown Line 2 Extension

Announced in the Land Transport Master Plan 2040 on 25 May 2019, the Downtown Line will be extended northwards to connect with the North-South Line at the new Sungei Kadut station.

The extension is expected to be completed by 2040.
