Breaking News: The first construction works supporting the planned DART+ West expansion to Meath and Kildare will begin this weekend, marking a significant step in Ireland’s long-term rail development programme.
Summary
Irish Rail will lower sections of track beneath two bridges near Hansfield to create space for future overhead electrification. The work will temporarily replace train services between Clonsilla and M3 Parkway with buses on Saturday and Sunday, with normal rail services expected to resume on Monday.
Breaking News Ireland: What is happening this weekend?
The enabling works will begin after the final train service to M3 Parkway on Friday evening. Around 140 Irish Rail staff are expected to work on the railway over the weekend, realigning the track formation and adapting bridges near Hansfield.
The changes are designed to make room for overhead electrical equipment that will be installed as part of the wider DART+ West project. The project aims to extend electrified DART services westwards to the M3 Parkway in County Meath and Kilcock in County Kildare.
- Friday evening: The final train service will operate to M3 Parkway before the works begin.
- Saturday and Sunday: Bus transfers will operate between Clonsilla and M3 Parkway.
- Monday: Normal rail services are expected to resume.
Passengers using the route should allow extra time and check Irish Rail service information before travelling. The temporary arrangement is particularly relevant to commuters connecting through Clonsilla and travelling towards Hansfield, Dunboyne and M3 Parkway.

Why the track work matters
Lowering the track at the bridges is an enabling measure rather than the full DART+ West construction programme. It removes a physical obstacle that would otherwise prevent the installation of overhead power lines above the railway.
Electrification is central to the planned expansion. It would allow electric DART trains to operate on routes that currently rely on diesel-powered services, while supporting more frequent and higher-capacity rail travel across the Greater Dublin Area.
Transport Minister Darragh O’Brien said the weekend works represented a move from planning towards delivery. He also said the Government would shortly consider business cases allowing DART+ West and DART Southwest to progress towards tendering and procurement.
What is the DART+ programme?
DART+ is a major rail investment programme intended to expand the existing electrified DART network well beyond its current routes between Dublin and Greystones, Malahide and Howth.
The planned extensions include:
- Drogheda on the northern rail line;
- Kilcock and M3 Parkway to the west;
- Hazelhatch and Celbridge to the southwest.
Irish Rail says the programme is intended to increase the electrified DART network from approximately 50km to 150km. It also aims to double passenger capacity in each direction during peak periods, from 26,000 journeys per hour to 52,000.
The wider programme includes new railway infrastructure, electrification, additional trains and a new depot. Irish Rail has ordered 285 carriages from Alstom, with a framework agreement that could potentially cover up to 750 carriages.
Who will benefit from DART+ West?
The project is expected to affect commuters and communities across west Dublin, Meath and Kildare. Residents near the planned stations could eventually gain access to more frequent electrified rail services and improved connections to Dublin city and the wider commuter network.
The expansion is also intended to increase capacity on existing routes. More trains and improved infrastructure could help support population growth while offering an alternative to car travel on busy commuter corridors.
However, the benefits will take time to materialise. The Government has indicated that construction and delivery will occur in sections, with an estimated buildout period of between six and 10 years depending on the part of the project.
Planning, land and procurement
Irish Rail has secured railway orders—effectively planning permissions—for most of the DART+ projects. A further application will be required for the proposed rail depot.
Property acquisition is also under way. The Transport Minister said compulsory purchase processes had begun and that engagement was taking place with approximately 200 landowners whose properties may be required for the projects.
The next major decision will be consideration of the business cases by Government. Once approval is secured, the projects can move towards full tendering and procurement.
What happens next?
- The Hansfield bridge and track works will take place over the weekend.
- Irish Rail will continue preparatory work for future electrification.
- Government business cases for DART+ West and DART Southwest are expected to be brought forward.
- Further procurement and construction details will be published as the projects progress.
- Construction will be delivered in phases rather than through a single opening date.
The first DART+ trains are expected to enter service on the Drogheda line in the second quarter of next year, according to Irish Rail. The western extensions to M3 Parkway and Kilcock will follow a longer development and construction timetable.
Frequently asked questions
Will trains run between Clonsilla and M3 Parkway this weekend?
No. Bus transfers are planned between Clonsilla and M3 Parkway on Saturday and Sunday while the enabling works are carried out.
Why are the tracks being lowered?
The track levels will be lowered at two bridges near Hansfield to provide enough clearance for overhead electrical wires and equipment needed for future DART electrification.
When will DART services reach M3 Parkway and Kilcock?
No fixed opening date has been announced. The expected delivery period is between six and 10 years, depending on the section of the programme.
What is the wider purpose of DART+?
DART+ is designed to expand the electrified rail network, increase train capacity and extend DART services to parts of Meath, Kildare, Louth and west Dublin.
Conclusion
This weekend’s track and bridge work is a relatively small intervention, but it has wider significance for Ireland’s transport network. It is the first visible construction step towards DART+ West and the planned extension of electrified rail services to M3 Parkway and Kilcock.
For passengers, the immediate impact is limited to temporary bus transfers between Clonsilla and M3 Parkway. For communities in Meath and Kildare, the more important message is that the DART+ programme is moving from plans and approvals towards phased delivery. This Breaking News Ireland development begins a long process, but it could reshape public transport across the western commuter belt.
