An Coimisiún Pleanála has published its decision to authorise the long-awaited construction of the MetroLink project running from Swords in north Dublin to Charlemont in the city centre.
A metro for Dublin was first proposed over 25 years ago when it was included in the then government’s 2000 transportation strategy. Authorisation for what was then called ‘Metro North’ was sought in 2008 and subsequently granted by An Bord Pleanála in 2010, by which time the economic crisis forced the State to shelve the project the following year in 2011. Subsequent efforts to revive the project in 2018 were thwarted by public opposition to the potential disruption of the planned route along the existing Green Luas line, leading to the resubmission of a revised route in November 2022. The Railway Order decision published on 2 October 2025 authorises construction, subject to conditions, three years after Transport Infrastructure Ireland (TII) submitted this revised application.
Railway Order
A Railway Order is an authorisation granted under the Transport (Railway Infrastructure) Act 2001 (as amended) which authorises the construction, maintenance, improvement and operation of railways. The application process for a Railway Order provides for environmental assessment and compulsory acquisition.
The Railway Order for MetroLink authorises the National Roads Authority (operating as TII) to carry out railway works and all works necessary to enable the construction, operation, maintenance and improvement of MetroLink, including the construction of an 18.8km primarily underground railway with 16 stations running from north of Swords at Estuary through to Charlemont in the south of Dublin City Centre.
Project Delivery
The Government intends to shortly bring forward legislative proposals to establish a dedicated statutory delivery body responsible for the construction of the project.
With the project moving from planning to construction, this new statutory body will look to provide a singular focus on delivering MetroLink in the public interest, reflecting the project’s importance as a “critical nation building project for Ireland’s future”.
Two large civil engineering contracts for the design and construction of the tunnels and station boxes and related civil infrastructure across two “halves” of the route are reportedly set to go to tender by the end of the year, with a number of firms said to be forming consortia to bid for this work. A private partner will then be sought to form a Public Private Partnership for the installation and operation of the railway.
Judicial Review
The Minister for Transport has stated that, subject to legal challenges, enabling works can begin in 2027 with completion targeted for 2034/2035. There is an 8 week period from the date that the Railway Order was made within which it may be challenged by judicial review. The hearing of any such challenge arising may be granted priority by the Courts and granted an early hearing date.
