Coloured purple on official maps, it is Singapore's third MRT line and the world's first fully-automated underground driverless heavy rail line.

The NEL was planned during the 1980s to alleviate traffic congestion on roads leading to the [[North-East Region, Singapore|northeast suburbs]] of the country. However, the project was delayed due to a lack of demand at that time. After the government's decision to go ahead with the project at an estimated cost of {{currency|5 billion|SGD|passthrough=yes}}, its alignment and stations were finalised in 1996 and construction began the year after. The line began operations on 20 June 2003. Two mid-line stations initially did not open with the rest of the line; [[Buangkok MRT station|Buangkok station]] opened on 15 January 2006, and [[Woodleigh MRT station|Woodleigh station]] began operations on 20 June 2011. A one-station extension to [[Punggol Coast MRT station|Punggol Coast station]] opened on 10 December 2024.

The driverless line uses the [[Moving block|moving-block]] [[Alstom]] Urbalis 300 [[Communications-based train control|CBTC]] signalling system. Three types of Alstom rolling stock – [[Alstom Metropolis C751A|C751A]], [[Alstom Metropolis C751C|C751C]] and [[Alstom Metropolis C851E|C851E]] – run on the NEL, which is powered by an [[overhead line]]. The NEL is Singapore's first [[Art-in-Transit]] line, with 19 artworks displayed across its 17 stations. The stations are wheelchair-accessible, and most of them are Civil Defence shelters designed to withstand airstrikes and chemical attacks.

The Mass Rapid Transit Corporation (MRTC) first proposed an additional MRT line serving the northeastern areas of [[Punggol]] and [[Jalan Kayu]] in September 1984.<ref>{{Cite news |last=Lim |first=Soon Neo |date=26 September 1984 |title=Study on Future North-East Line |page=1 |work=[[Business Times (Singapore)|Business Times]] |publisher=[[Singapore Press Holdings]] |url=https://eresources.nlb.gov.sg/newspapers/Digitised/Article/biztimes19840926-1.2.4 |access-date=22 August 2021 |via=NewspaperSG}}{{cbignore}}</ref> In its preliminary studies, the [[Ministry of Communications and Information|Communications Ministry]] concluded that existing roads would be inadequate for projected traffic into housing estates set to be built in the 21st century. To minimise the impact on other development, the Ministry developed plans to determine which parcels of land would be needed for the new MRT project.<ref>{{Cite news |last=Dhaliwal |first=Rav |date=26 September 1984 |title=Study into MRT North-East Line |page=44 |work=[[The Straits Times]] |publisher=[[Singapore Press Holdings]] |url=https://eresources.nlb.gov.sg/newspapers/Digitised/Article/straitstimes19840926-1.2.66 |access-date=22 August 2021 |via=NewspaperSG}}{{cbignore}}</ref> In December of that year, a British consultancy team consisting of [[Halcrow Group|Sir William Halcrow and Partners]], [[Merz & McLellan]] and [[London Transport (brand)|London Transport]] International was appointed by the MRTC to look into possible routes for the line.<ref>{{Cite news |last=Dhaliwal |first=Rav |date=7 December 1984 |title=British Team Selected |page=1 |work=[[The Straits Times]] |publisher=[[Singapore Press Holdings]] |url=https://eresources.nlb.gov.sg/newspapers/Digitised/Article/straitstimes19841207-1.2.7 |access-date=22 August 2021 |via=NewspaperSG}}{{cbignore}}</ref>

In March 1986, the British consultants drew up a tentative route from [[Outram Park]] to Punggol. The line would connect to the existing MRT system at [[Dhoby Ghaut MRT station|Dhoby Ghaut station]] and pass through [[Kandang Kerbau]] and [[Hougang]], paralleling the major Serangoon and Upper Serangoon Roads. A branch line from Hougang to Jalan Kayu was also proposed. The segment of the line in the city would be underground, and the northern portion after [[Outer Ring Road System|Braddell Road]] would be elevated.<ref>{{Cite news |last=Dhaliwal |first=Rav |date=30 March 1986 |title=Serangoon and Hougang May Be Next on MRT Line |page=10 |work=[[The Straits Times]] |publisher=[[Singapore Press Holdings]] |url=https://eresources.nlb.gov.sg/newspapers/Digitised/Article/straitstimes19860330-1.2.19.18 |access-date=22 August 2021 |via=NewspaperSG}}{{cbignore}}</ref>

Mah, engaging with grassroots leaders in October 1995, said that residents would have to be prepared to pay higher fares on the NEL to cover the line's cost and initial losses. His position was divisive; some leaders felt that it would be unfair to the residents, and others were confident that residents would be willing "to pay for a better quality of life". Increased fares for the entire network were also suggested, but Mah said that it would be more difficult to implement. He assured leaders that he would recommend construction of the line to the government.<ref name="speed up">{{Cite news |last=Leong |first=Chan Teik |date=23 October 1995 |title=Govt Wants to Speed Up Construction: Mah |page=1 |work=[[The Straits Times]] |publisher=[[Singapore Press Holdings]] |url=https://www.straitstimes.com/multimedia/graphics/assets/images/ST175/NewspaperSG/1995-10-23/full.jpg |url-status=live |access-date=22 August 2021 |archive-url=https://web.archive.org/web/20230124042031/https://www.straitstimes.com/multimedia/graphics/assets/images/ST175/NewspaperSG/1995-10-23/full.jpg |archive-date=24 January 2023}}</ref><ref>{{Cite news |last=Leong |first=Chan Teik |date=9 October 1995 |title=Mah's Poser: Will Users Pay More to Get It Faster? |page=3 |work=[[The Straits Times]] |publisher=[[Singapore Press Holdings]] |url=https://eresources.nlb.gov.sg/newspapers/Digitised/Article/straitstimes19951009-1.2.8.4 |access-date=22 August 2021 |via=NewspaperSG}}{{cbignore}}</ref>

The depot can accommodate up to 44 trains,{{sfn | Leong |2003 | p=207}} with three additional stabling tracks being built for the NELe as of 2019.<ref name="Siemens Tan 2019"/> It also houses [[Light rail|LRT]] trains for the Sengkang and Punggol LRT lines above the depot.{{sfn | Leong |2003 | p=201}}<ref name="LTA two-car 2021">{{Cite web |date=5 February 2021 |title=New Two-Car Trains for Sengkang-Punggol LRT |url=https://www.lta.gov.sg/content/ltagov/en/newsroom/2021/2/news-releases/New_two-car_trains_for_SPLRT.html |url-status=live |archive-url=https://web.archive.org/web/20210828100151/https://www.lta.gov.sg/content/ltagov/en/newsroom/2021/2/news-releases/New_two-car_trains_for_SPLRT.html |archive-date=28 August 2021 |access-date=28 August 2021 |publisher=[[Land Transport Authority]]}}</ref>

Its facilities include a four-storey administrative building, maintenance bays, a workshop and an automated warehouse. The depot's workshop has equipment which can raise an entire train for repairs, Singapore's first such workshop. Using the NEL's signalling system, train movement in the depot is mainly automatic. Staff members access the area via three dedicated tunnels for safety reasons.{{sfn | Leong |2003 | pages=202–204}}

The OCC also controls the equipment and systems of tunnels, stations, power substations and the depot, which are integrated into one terminal. The systems are managed by four or five rotating teams working around the clock. Alongside a training and software-development room, the OCC has a depot control centre to monitor and supervise its operations.{{sfn | Leong |2003 | p=207}}<ref>{{Cite news |date=8 June 2003 |title=I Saw This Baby Through Its Birth |work=[[The Straits Times]] |publisher=[[Singapore Press Holdings]]}}</ref>

===Signalling===
The NEL is fully automatic,<ref name="who's driving">{{Cite news |date=16 April 2003 |title=Who's Driving the Train? |page=20 |work=[[The Straits Times]] |publisher=[[Singapore Press Holdings]]}}</ref> using Alstom's Urbalis 300 [[moving block|moving-block]] signalling system.<ref name="Alstom PDF"/> The NEL is the world's first fully automated heavy-rail system.<ref name="CNA 2022">{{Cite web |last=Yeoh |first=Grace |date=12 November 2022 |title=In Focus: 35 Years of People and Purpose |url=https://www.channelnewsasia.com/singapore/mrt-35th-anniversary-history-people-staff-3056206 |url-status=live |archive-url=https://web.archive.org/web/20230228023434/https://www.channelnewsasia.com/singapore/mrt-35th-anniversary-history-people-staff-3056206 |archive-date=28 February 2023 |access-date=28 February 2023 |website=[[CNA (TV network)|Channel NewsAsia]] |publisher=[[Mediacorp]]}}</ref> Its construction allowed the LTA to explore, integrate and implement new and existing technology as part of its vision of a fully-automated system.{{sfn | Leong |2003 | pages=19, 24}} The line's [[automatic train control]] (ATC) is based on Alstom's MASTRIA software, which also manages its [[automatic train protection]] (ATP) and [[automatic train operation]] (ATO) GoA 4 (UTO). The Urbalis system also includes a computer-based Interlocking system which controls the track switches and interfaces with the ATC and the data-management system. The DMS, monitored by station staff, oversees the signalling equipment, platform doors and trains.<ref name="Alstom PDF"/>

The ATP system maintains a buffer between trains.{{sfn | Leong |2003 | p=226}} The minimum permitted distance is {{convert|30|m|ft}}, although the average distance between trains is at least {{convert|600|m|ft}}.<ref name="Safe driverless"/> Using [[microwave]] technology, the IAGO waveguide (Informatisation et Automatisation par Guide d'Onde or waveguide transmission line system for computer and automation applications){{sfn | Leong |2003 | p=225}} allows two-way communication between trains and monitors the trains' positions and movements. If a train enters the buffer, the ATP automatically adjusts the train's speed.{{sfn | Leong |2003 | p=226}}

At least 500 computer systems control the NEL. In case of a glitch, backup systems would take over; the system would "go to sleep" if it experiences a severe malfunction. In the event of system failure, drivers would be deployed to manually operate the trains.<ref name="driverless and eyes"/><ref name="who's driving" /> The NEL maintains its "[[Failure rate|mean kilometres between failures]]" target of one million train-km ({{Convert|1|e6km|mi|disp=output number only}} train-miles). As part of an NEL refurbishment programme announced on 17 December 2018, parts of the power and signalling systems were serviced and new rail crossings and tracks installed.<ref name="Lim 2018"/>

==Station facilities==
Every station has a passenger service centre (PSC) on its concourse.{{sfn | Leong |2003 | p=216}} The PSCs are generally curved, unlike the boxier designs of those in older MRT stations.{{sfn | Leong |2003 | p=217}} In addition to assisting passengers and checking and topping up their fare cards, the PSC staff monitors and controls the functions of connecting tunnels and communicates with the OCC at the depot. When a station is used as a civil-defence (CD) shelter, the PSC becomes the command centre.{{sfn | Leong |2003 | p=216}}

Each NEL station is equipped with "energy-smart" [[Otis Worldwide|Otis]] escalators connecting its levels. Their speed is reduced by half when not in use, reducing energy consumption and wear and tear. The Woodleigh station has one of the longest sets of escalators at {{convert|38.5|m|ft}}. In addition to escalators, Dhoby Ghaut is the first MRT station with a set of {{convert|55|m|ft|adj=on}} [[Moving walkway|travellators]] which link the NEL and NSL platforms.{{sfn | Leong |2003 | p=210}}

All NEL stations have lifts which provide step-free access to their platforms.<ref name="sbstransit.com.sg 2006">{{cite web | title=Station Facilities | publisher=[[SBS Transit]] | url=http://www.sbstransit.com.sg/transport/trpt_nel_facilities.aspx | archive-url=https://web.archive.org/web/20150325183317/http://www.sbstransit.com.sg/transport/trpt_nel_facilities.aspx | archive-date=25 March 2015 | url-status=dead | access-date=24 January 2023}}</ref> Most of the lifts have glass doors, which improve appearance and enhance security. Each lift has a communications system, connected to the station's PSC. If a lift stalls during a station blackout, a battery-powered backup system provides lighting and ventilation for four hours.{{sfn | Leong |2003 | p=213}}

The NEL has the MRT's first tactile system. Consisting of tiles with raised rounded or elongated studs, the system intends to guide visually-impaired commuters through a station on a dedicated route from entrance to platforms.<ref name="NEL opens"/>{{sfn | Leong |2003 | p=248}} Station seats have armrests to assist those who have difficulty getting up.{{sfn | Leong |2003 | p=250}}

These accessibility features were part of the recommendations of a LTA [[working group]] set up to improve accessibility on the MRT network. Associations representing the disabled were also consulted. The group completed its findings in 1999; only some of its recommendations had been adopted by 2003, since station infrastructure was nearly completed by then.{{sfn | Leong |2003 | p=248}}
