The original idea for the two Metro lines in Dublin can be attributed to the November 2001 "Platform for Change" report by the Dublin Transportation Office (now part of the National Transport Authority).[10] The purpose of the report was to come up with an integrated transportation strategy for the greater Dublin region. In its report, the DTO outlined plans for three Metro lines. The first was a north–south line which would run from Swords to Shanganagh via Dublin Airport, Finglas, Broadstone, the city centre, Ranelagh, Sandyford and Cherrywood. The second would link Tallaght West to Tallaght and then continue through the south-western suburbs of Dublin to the city centre. The third line would run in an orbital pattern, with a spur off the Swords-Shanganagh line at Finglas and then continue via Blanchardstown and Clondalkin to Tallaght, where it would connect with the other line.

Dublin Airport carried over 21 million passengers in 2006. This figure was projected to grow rapidly (as it did to 27.9 million by 2016).[11] As a result, Transport Infrastructure Ireland identified a medium-capacity public-transport link to Dublin Airport as one of the most important gaps in the Dublin rail network. Two options were seen as a solution to the problem:

• A spur off the existing DART line to Dublin Airport, as proposed by Iarnród Éireann.
• A metro system, running from Swords through Dublin Airport and on to the city centre, in line with the National Transport Authority's suggestions.

The metro option emerged as the preferred option, as it provided both an airport link and a commuter link. It was described by Transport Infrastructure Ireland as "an important commuter link for the communities and institutions of North Dublin City and County".[12] Metro North (from Swords to St. Stephen's Green) and Metro West were adopted as government policy with the launch of the Transport 21 programme in 2005.

Three potential routes for the then called Metro North were published by the Railway Procurement Agency in February 2006. The first route option went through Finglas and made use of the former Broadstone railway alignment. The second route option went through Ballymun and was eventually adopted as the final route. The third route option went through Whitehall. After public consultation, the RPA announced in October 2006[13] that they had selected a routing known as the 'East/Central Combined Route'. that ran through Ballymun. A slightly updated route, with changes in proposed station names, some modifications to station locations, and details of proposed overground and underground routes through Swords was released by the RPA in March 2008.[14]

On 22 March 2007, Transport Infrastructure Ireland began the procurement process for Metro North. In October 2007 it announced that it had a shortlist of four consortia interested in building Metro North. Draft Environmental Impact Statements were published in early 2008.

On 17 September 2008, the RPA applied for a railway order to An Bord Pleanála.[15] Oral hearings were heard during 2009 and 2010.[16]

On 5 October 2011, Metro North was granted planning permission by An Bord Pleanála.[17]

It was speculated by the media that the Metro North Project would be indefinitely deferred on 12 August 2011 following a review by Leo Varadkar, then Minister for Transport, Tourism and Sport. This was confirmed on 10 November 2011.[18]

In September 2015, it was announced that Metro North was being relaunched, with a revised opening date of 2027.[19]

In September 2021, government representatives indicated that the 2027 target would not be met and "was never likely to be achievable",[6] with some reports projecting that construction would not commence before 2027.[2] While included in the "National Development Plan 2021-2030", the plan included "no completion dates" for the proposed project.[3]

On 22 March 2018, the National Transport Authority announced revised plans for the former Metro North railway line, now called 'MetroLink'.[20]

The new plan incorporated considerable changes from the original.[21] If built as proposed, MetroLink would provide additional integration with heavy rail by including a new integrated heavy rail and metro interchange station at Glasnevin to provide transfers to and from the proposed DART+ West and South West lines. In addition, the updated route proposal included an interchange with existing DART services at Tara Street station. The tunnel construction method was changed from twin-bore to single bore to minimise disruption and reduce costs. Some of the MetroNorth stations would have required expensive mined construction, while all MetroLink stations are proposed to be constructed using the simpler cut and cover method. MetroLink is also intended to be driverless with platforms proposed to incorporate platform screen doors, while MetroNorth was designed to be manually operated by drivers by line-of-sight.

Initially the route was to extend further south to Sandyford, subsuming the Luas Green Line tracks from Charlemont down to its final destination in Sandyford. According to those plans, Luas services on the Green Line would cease between Sandyford and Charlemont, and be replaced by Metro services.[22] In March 2018 public consultations were held[23] and the plan met with considerable opposition regarding the potential closure of the Green Line for an undetermined amount of time and issues regarding pedestrian and cyclist permeability along the line.[24] As a result, revised plans were published in March 2019, where the Metrolink line would be delivered in two phases, meaning the Green Line would not be upgraded during the first phase.[25] The Green Line Upgrade would happen as a second phase at a later date after Metrolink from Swords to Charlemont was operational. By developing in two phases the closure of the Green Line could be reduced and more time given to upgrading the existing pedestrian crossings to be fully grade separated through the use of underpasses.[26]

Before this opposition, a railway order was due to be sought for MetroLink in the third quarter of 2019. As of 2018, the revised MetroLink project was proposed to open in 2027.[4]

In December 2019, test drilling for boreholes began for the line.[27] Engineering consultant firm SNC-Lavalin was appointed by Transport Infrastructure Ireland in March 2020 as operations advisor for the project.[28] Due to the COVID-19 pandemic in the Republic of Ireland, work was halted, however in November 2020 ground investigation works resumed with work in Swords.

Originally the Railway Order was intended to be submitted in the first half of 2021[1] but actual submission occurred in September 2022.[29] As of April 2023, a number of bodies (including Irish Rail, Dublin Airport, Abbey Theatre and Mater Hospital) raised concerns about aspects of the proposals outlined in the planning application.[30]

In 2006 Eamon Ryan, then transport spokesperson for the Green Party, called for the underground section of Metro North to be extended south to Beechwood, where it would then surface and provide a direct link to the Luas Green Line.[34] This option would allow passengers to travel from the south of the city to the north, without having to change mode of transport.

When the Luas Green Line was constructed, it was designed to allow metro trains to potentially operate on the line in the future.[35] In the National Transport Authority's Draft Transport Strategy for the Greater Dublin Area 2016–2035, it was proposed that the Metro North tunnel should be extended southwards to meet the Luas Green line in the Ranelagh area. The Luas Green line would be converted to a metro line, with Luas services on the line ending and being replaced by metro services.[36]

In March 2019, the revised plans were released with the intention to upgrade the Green Line after the northern section is operational.[37] As of 2016, it remained part of the transport strategy to upgrade the Green Line to be capable of running metro services, extending the metro to Sandyford and eventually to Bride's Glen.[36]

In 2020, it was reported that the NTA was assessing additional potential metro provision; with a southwest line serving Terenure, Rathfarnham and Knocklyon, or a southeastern line serving University College Dublin.[38]

Metro West (proposed)

Metro West (Irish: Meitreo Thiar) was proposed to run from an intersection with Metro North, just south of the airport at Santry, and from there pass through Blanchardstown, Liffey Valley, and Clondalkin before joining the Luas Red Line to continue towards Tallaght. Metro West was planned to be entirely above ground, at road level, and 25.5 kilometres long (15.8 mi). Planning on the Metro West Project was suspended in September 2011 following a review by Leo Varadkar, then Minister for Transport, Tourism and Sport, as money to construct the new railway would not be available in the foreseeable future.[39]

Two potential routes for Metro West had been published by the Railway Procurement Agency in January 2007. Following discussions and a public consultation process, a preferred route was announced in July 2007. This route started at Tallaght, running through Belgard, Clondalkin, Liffey Valley, Blanchardstown. Stops were also proposed for the National Aquatic Centre and Abbotstown, before continuing in the direction of Sillogue and Harristown. Following Harristown it would link with the proposed Metro North line, for a combined length of 25 km.[40]

Metro West plans, published in 2007, proposed lines which would run overground, with some tunnels and bridges to avoid major road junctions.[41] In addition to the proposed link with Metro North, the line was proposed to interchange with the Luas at Tallaght and Belgard, rail services at Fonthill and Porterstown and Dublin Bus services at a number of other stops.[42]

Metro West was proposed to serve the northern parts of Finglas via stops at the N2 and Meakstown. When developing options for Metro West, the Railway Procurement Agency (RPA) considered routes south of the M50, serving Finglas more directly. Ultimately, these routes were not deemed feasible.[43]

On 11 November 2008, the RPA chose their preferred route for Metro West, including indicative stops, depot and Park and Ride locations. The preferred route for Metro West ran from Tallaght to Metro North at Dardistown, via Clondalkin, Liffey Valley and Blanchardstown. The planned route would interchange with (from south to north) the Luas Red Line, Kildare Railway Line, Luas Line F (to Lucan), Maynooth Railway Line and Metro North Line, as well as local bus services.[44]

By 2016, Metro West had been excluded from the National Transport Authority's "Transport Strategy For The Greater Dublin Area 2016-2035". As of 2018, Metro West was not due to be considered for government funding until after 2035.[45]
