First enabling works for the planned DART+ West extension to Kilcock in County Kildare and the M3 Parkway in County Meath will begin this weekend. The initial project activity will require temporary bus transfers between Clonsilla and the M3 Parkway on Saturday and Sunday.
Key details of the DART+ West works
Irish Rail said the weekend disruption is linked to preparatory work for the DART+ West project, which aims to support the future electrification and expansion of rail services west of Dublin.
The first works will focus on lowering railway tracks at two bridges near Hansfield. The changes are intended to create the clearance needed for overhead electrical equipment in a later phase of the project.
- Where: Between Clonsilla and the M3 Parkway, with works taking place near Hansfield.
- When: Saturday and Sunday, beginning this weekend.
- Why: To prepare the route for future electrification.
- Passenger impact: Bus transfers will operate between Clonsilla and the M3 Parkway.
What passengers need to know
Passengers travelling on the affected section should allow additional time and check Irish Rail travel information before setting out. The temporary bus service is designed to replace train connections between Clonsilla and the M3 Parkway while the enabling works take place.
Travellers may also need to consider connections at Clonsilla, particularly if they are continuing towards Dublin or using other public transport services. Exact journey times can vary depending on traffic and interchange arrangements.

Why the project matters for Dublin, Kildare and Meath
DART+ West is part of a wider programme to expand and modernise rail capacity in the Greater Dublin Area. The planned route would extend the benefits of electrified DART services beyond the existing network, linking communities in west Dublin with destinations including the M3 Parkway and Kilcock.
For residents and commuters, the project is significant because improved rail capacity can offer an alternative to car travel on busy routes into Dublin. A completed electrified service could also support more frequent trains, better connectivity and lower transport emissions, although the final passenger benefits will depend on the delivery of later construction and operational stages.
Enabling works are an early stage of the DART+ West plan
Track lowering is a technical preparation measure rather than the launch of a new passenger service. The work is needed because electrified railways require infrastructure to accommodate overhead wires and associated equipment.
By modifying the railway profile at the two bridges, engineers can prepare the line for future electrification while addressing clearance constraints in advance. This type of enabling work is an important part of large-scale rail construction because it allows later stages to proceed safely and efficiently.
The works near Hansfield do not mean that DART services to Kilcock or the M3 Parkway will begin immediately. A timetable for future services will depend on the wider delivery of the DART+ West project.
What happens next?
Irish Rail is expected to continue coordinating temporary passenger arrangements as work progresses. The weekend bus transfers are the immediate impact for travellers, while the broader project involves a much larger programme of railway, electrical, station and signalling improvements.
Passengers should use official Irish Rail updates for the latest information on replacement buses, station arrangements and possible changes to journey times. Motorists and commuters may also wish to plan for heavier traffic around interchange points during the affected period.
