Station names of the North South Line.

The North South Line (NSL) is the first Mass Rapid Transit (MRT) line in Singapore. The line is 45 km long with 27 stations, including the upcoming North South Line Extension, slated to be completed by 2014 and the planned station, Canberra. Travelling from one end of this line to the other end takes about one hour, and this line is coloured red on the rail map.

As the name implies, the line connects central Singapore to both northern and southern parts of the island. Cross-platform interchange with the East West Line is provided at Jurong East, City Hall and Raffles Place while transfer to the North East Line is possible via a linkway at Dhoby Ghaut. Connections to the Circle Line are provided at Bishan, Dhoby Ghaut and Marina Bay and a linkway via Esplanade. The North South Line will interchange with a future extension of the Downtown Line at Newton and with the future Thomson Line at Woodlands, Orchard and Marina Bay.


Initial system[edit]

Second phase of development (Woodlands Extension)[edit]

  • 10 February 1996: YishunChoa Chu Kang (the Choa Chu Kang branch of the East West Line became part of the present North South Line)

During the initial planning of the Woodlands Extension MRT line, Sembawang station was only intended as a provisional station to be built at a later date due to the underdevelopment of the town and Kranji station was not planned. But on the second round of planning, the government decided to build these station and omit Sungei Kadut station from the plan. Sungei Kadut station will be built later if the town's population justifies the necessity for the station.[1]

Jurong East Modification Project (JEMP)[edit]

The Jurong East Modification Project consisted of the construction of a new platform and the addition of a fourth track to Jurong East Station.[2] It has been in use since 27 May 2011.[3] Originally it opened from 7am to 9am, this was expanded from 27 December 2011 and it also opens during the evening peak hour.[4]

North South Line Extension (NSLe)[edit]

A 1-kilometre (0.6 mi), one station extension from Marina Bay was completed in 2014. The new Marina South Pier station will be located near the Marina Bay Cruise Centre Singapore in Marina Bay. The then-Minister for Transport, Raymond Lim, announced on 12 February 2009 that the completion date for the extension, initially due for completion in 2015, will be brought forward by a year to 2014.[5] On 7 March 2012, Minister for Transport, Mr Lui Tuck Yew, gave his speech on Committee of Supply Debate 2012 in Parliament of Singapore that North South Line Extension expected to be completed in 2014.[6][7] It opened on:

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 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,[8] 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.[9] They were first installed at Jurong East and Yishun stations in 2009 as trial runs.[10]

Installation began on May 2011 at Ang Mo Kio MRT Station, and by 14 March 2012, Kranji MRT Station, the last station for installation began operational (and please refer to the elevated MRT stations for more details on "installation of half-height platform screen doors").[11]

Line disruptions[edit]

On 15 December 2011, services between Bishan and Marina Bay stations were suspended due to 40 metres of the power rail being damaged between City Hall and Dhoby Ghaut stations. Trains along the stretch were stalled, causing a disruption to the train service for almost 5 hours. Train service fully resume at 11.40pm.[12][13]

On 17 December 2011, a similar fault caused a 7-hour disruption between Ang Mo Kio and Marina Bay stations.[14][15] According to SMRT, the disruption was caused by damage to the third rail and the trains' collector shoes. Seven trains were damaged in this incident.[16]

These two service disruptions on the North-South Line were the worst ever since SMRT started operation for 24 years.[17]
