Station names of the East-West Line.

The East West Line (EWL) is the second Mass Rapid Transit line in Singapore. The line is currently 57 kilometres (35 mi) long with 35 stations,[1] including four more to be constructed by 2016, known as the Tuas West Extension (TWE), making it the longest MRT line in Singapore. It takes about 70 minutes to travel from one end to the other. The line is coloured green on MRT system maps.

The Tuas West Extension (TWE), a westward four-station extension of the East West Line from Joo Koon, is currently under construction.

Overview[edit]

As its name implies, the line connects central Singapore to both eastern and western parts of the island, with an additional branch to Changi Airport from Tanah Merah, where you have to change at Tanah Merah. There is a short tunnel between Kembangan and Bedok because it ascends into the hill at Siglap, and there is also a longer tunnel due to the space limitations between Kallang and Redhill. It passes through the centre median of roads in Tanah Merah, Bedok, Queenstown, Commonwealth, Dover and Clementi. It takes commuters to schools (Nanyang Technological University and Singapore Polytechnic are nearby), places of interest (Jurong Bird Park and Science Centre), and skirts past the three rivers (Singapore River, Rochor River and Kallang River).

It is the only line that connects the east to the city area until 2017, when the Downtown Line and Thomson-East Coast Line (East Coast section) is built.

History[edit]

The East West Line is the second line to be built, running from City Hall to Outram Park on 12 December 1987. It was extended to Clementi on 12 March 1988 and to Lakeside on 5 November 1988. Additionally, the eastern extension was opened on 4 November 1989, and to Pasir Ris on 16 December 1989. The last station, Boon Lay was opened on 6 July 1990.

Tuas West Extension (TWE)[edit]

On 11 January 2011, the Tuas West Extension was announced. It is an extension of the East West Line from Joo Koon to Tuas Link. The stations — Gul Circle, Tuas Crescent, Tuas West Road and Tuas Link — will extend MRT connectivity to the Tuas area and is expected to serve more than 100,000 commuters daily.[2]

When completed in 2016, the Tuas West Extension will be an extension of the East West Line from Joo Koon, consisting of a 7.5 km long twin-tracked MRT viaduct, four aboveground stations and a depot. The MRT viaduct is also integrated with part of a 4.8 km long road viaduct along Pioneer Road, which will increase the road capacity to cope with anticipated increase in traffic. A 26-hectare depot will also be built to provide stabling and maintenance facilities for the additional trains that will be bought for the extension and to cater for future expansion of the line.[3]

On 4 May 2012, the Land Transport Authority marked the start of construction of the Tuas West Extension with a groundbreaking ceremony at the site of the future Tuas Link station.[2]

Half-height platform screen door installations[edit]

There were calls for platform screen doors to be installed at above-ground stations after several incidents in which passengers were killed or seriously injured by oncoming trains when they fell onto the railway tracks at above-ground stations. Underground stations already featured the doors since 1987. The authorities initially rejected the proposal by casting doubts over functionality and concerns about the high installation costs,[4] but made an about-turn when the government announced plans to install half-height platform screen doors on the above-ground stations in January 2008, citing lower costs due to it becoming a more common feature worldwide.[5] They were first installed at Jurong East and Pasir Ris stations in 2009 as trial runs.[6] Installation of platform screen doors began at Clementi and Lakeside stations on April 2010. On 31 August 2011, the last station, Expo began installation of half-height platform screen doors.

Timber to concrete sleeper replacement works[edit]

Timber sleepers are designed to last 15 to 25 years. They have to be replaced when they are near the end of their lifespan, or when they show signs of significant wear and tear. New sleepers will allow trains to move along the tracks smoothly and without the current speed restrictions. Passengers can look forward to safe, smoother and faster train rides. In view of this, SMRT had to adjust last train timings earlier on the East West Line. It is expected to be completed by December 2016, and was divided into four phases: Phase 1 (Pasir Ris-Aljunied), Phase 2 (Aljunied-Outram Park), Phase 3 (Outram Park-Jurong East) and Phase 4 (Jurong East-Joo Koon). Pioneer and Joo Koon were exempted from the sleeper replacement work as they are new stations.

SMRT used to operate the branch sector of  EW4  Tanah Merah to  CG2  Changi Airport as a through line from Boon Lay from 18 November 2001 until 22 July 2003, when it was replaced with a shuttle service.[7]

Similarly to the preceding Circle and Downtown MRT Lines announced earlier, the four stations along the Tuas West Extension were open for public consultation from 16 December 2011 to 15 January 2012. The finalised station names were announced on 13 April 2012.[8]

Rolling stock[edit]

Four batches of rolling stock are in service on the line, i.e., the C151s, the C651s, the C751Bs and the C151As. These trains operate from the two depots along the line, the Ulu Pandan Depot near Jurong East and the Changi Depot after Tanah Merah.

Train Control[edit]

The East-West Line is currently equipped with a Fixed Block Signalling System with ATP by Westinghouse, and is currently phasing out the old signalling system and installing a new SelTrac® CBTC moving block signalling system by Thales [9] The new signalling system is expected to be operational by 2016 and trains will run in GOA 2 mode. Thales Nettrac MT will be installed for the OCC of the network. Automatic platform screen doors by Westinghouse were originally installed when the line opened and Automatic Platform Screen Gates by Westinghouse were installed at a later date on elevated stations except for Tuas West Extensions Stations which are manufactured by Fangda Group.
