MetroLink Dublin


In competition with other leading companies in the sector, IDOM won the Engineering Services Contract for the implementation of the MetroLink – a 26 km high-frequency rail through Dublin. The project will be developed in 5 stages over the next 10 years, from preliminary design to start-up. Our extensive experience gained on similar international projects, as well as the demonstrated capacity of our design teams, were deciding factors for Transport Infrastructure Ireland (TII) and the National Transport Authority (NTA) of Ireland to place their confidence in IDOM to develop the project.

Urban transport 4.0

MetroLink is a project tailored to the needs of the society it serves. Consultations are conducted with the public and all affected stakeholders including educational and health institutions; sport and business organisations; other transport companies and elected representatives. Their opinions are sought and analysed by the client to ensure the route, construction and operation of MetroLink are optimised for the benefit of all users. This exciting dynamism adds dimension, nuance and richness to the services we are providing. We feel connected and part of the community. We are developing an urban transport system 4.0: consensual, accessible, efficient, respectful to the environment and sensitive to all social sectors.

Jacobs is our partner in this stimulating challenge. IDOM is developing all the engineering associated with the implementation of MetroLink as an urban rail system: the layout of the tunnels, viaducts and stations, in addition to the railway systems, rolling stock and depots/workshops. Including the operations study. BIM Level 2 is being used for the design, across all disciplines.

MetroLink, the first metro line in Dublin, will link the north and south of the city along 26 km. The centre of Swords will connect to the airport, and then on to the city centre, stopping at the legendary O’Connell Street. There will be two connections with Irish Rail, and then the service will travel southwards from Charlemont to Sandyford. The line has 25 stations and the alignment adapts to the urban environment, running underground, in open sections, elevated or at grade level, depending on the section. On the southern section, the existing tram line (Luas) will be upgraded to the automatic Metro Standard (GoA 4), the standard to be used for the operations of the entire MetroLink system.

The interactive route map is now available on MetroLink web, as well as the Preferred Route document.
