As the Deputy may be aware, the National Transport Authority (NTA) has responsibility for the planning and development of public transport infrastructure in the Greater Dublin Area (GDA) including, in consultation with Iarnród Éireann, the DART+ programme.
The DART+ programme, which comprises five different projects in and around the GDA, will triple the length of the electrified network from circa 50km to 150km and double city centre capacity from 26,000 passengers per hour per direction to 52,000 during peak hours. This will significantly enhance access to high capacity public transport across the GDA.
DART+ South West will extend DART services from the City Centre to Hazelhatch and Celbridge including four-tracking from Park West to Heuston. A Railway Order was approved for DART+ South West by An Coimisiún Pleanála in November 2024. In addition, procurement for DART+ South West and West is progressing with pre-qualification questionnaires (PQQ) notices for Design and Build works advertised in May 2025.
The NDP Sectoral Investment Plan, published by the Department in November, sees the allocation of €22.3 billion in Exchequer resources to Transport, along with an additional allocation of €2 billion from the country's Infrastructure, Climate and Nature Fund to support the development of MetroLink. Of this total allocation, funding of circa €10 billion for public transport infrastructure is earmarked from 2026 to 2030, in addition to the €2 billion for MetroLink, primarily in line with the Department’s NIFTI intervention hierarchy of Maintain, Optimise, Improve, and New. This approach involves prioritising investment in the protection and renewal of existing assets before investing in new ones, on economic and environmental grounds.
The funding under the NDP Sectoral Investment Plan will see significant advancements made in a number of public transport projects, including DART+ West. This funding will also allow Compulsory Purchase Orders to progress for DART+ South West starting next year and provide for procurement progress for the project, with some of the framework contracts being established in common for DART+ West and DART+ South West.
The Department of Transport will continue to explore opportunities for additional funding, including through funding streams such as the European Union Connecting Europe Facility (CEF), to compliment national Exchequer funding which may allow some projects to proceed to construction earlier than currently anticipated, including DART+ South West.
Noting the NTA's responsibility in the matter, I have referred the Deputy's question to the NTA for a more detailed reply. Please contact my private office if you do not receive a reply within 10 days.
