Welcome to the DART+ West Project

The first of the infrastructural projects of the DART+ Programme to be delivered will be the DART+ West project. This rail improvement project will provide a sustainable, electrified, reliable and more frequent rail service to our customers, improving capacity on Maynooth and M3 Parkway to city centre rail corridors. The DART+ West project has now sought statutory approval for its design, with the submission of a Railway Order application to An Bord Pleanála on the 29th July 2022. The DART+ West Railway Order application documentation is available on a standalone website.

DART+ West Introduction

The DART+ West project has applied for a Railway Order to An Bord Pleanála on the 29th July 2022. 

This DART+ West Railway Order application is based on a design which takes account of the option appraisals and consideration of the feedback received from non-statutory public consultations undertaken between August 2020 and April 2022. The consideration of feedback received from public consultation no. 1 is found in PC1 Findings Report. The consideration of feedback received from public consultation no. 2 (including the local Ashtown consultation) is found in PC2 Findings Report. Both are included in the Railway Order application.

An Bord Pleanála is the competent authority responsible for making the decision whether or not to grant the Railway Order. An Bord Pleanála will consider any submissions by any persons, made in writing from the 05 August 2022 until the 30 September 2022. 


The project will see:

  • Increase train capacity from the current 6 trains per hour per direction up to 12 trains per hour per direction subject to demand. Passenger capacity will increase from 5,000 in 2019 to 13,200 passengers in 2025.
  • Reduce carbon emissions through the deployment of new electric trains.
  • Support growing communities, businesses, and future development by providing high-quality integrated public transport service in line with Government policy including the National Planning Framework and Climate Action Plan.
  • Your local knowledge will inform the design, help us to improve the project and ensure it will be a success for you and the communities it will serve.

Delivery of this DART+ West will support existing communities and support future sustainable development. It will serve all existing stations along the railway corridor between Maynooth Station and M3 Parkway Station to Connolly Station and to the proposed Spencer Dock Station using electrical power, which has a lower carbon footprint than the current diesel trains. The frequency and quality of service will provide a viable transport alternative for surrounding communities other than private car travel. This will assist in Ireland reducing road congestion and greenhouse gas emissions from transport, thereby helping to combat climate change.

The electrification of the rail line will predominantly follow the existing railway corridor. Works outside of Iarnród Éireann lands will be required at a number of locations for some of the scheme elements such as:

  • Level crossing replacements;
  • Proposed depot, including rail and road realignment;
  • Proposed new Spencer Dock Station;
  • Bridge reconstruction and/or improvements; 
  • Construction of substations (to facilitate the provision of power to the line), and
  • Use of land for temporary construction/storage compounds and all ancillary works required for the project.

Key Infrastructural Elements

DART+ West is seeking to modernise and optimise the existing railway between Maynooth and M3 Parkway to Connolly Station and the proposed Spencer Dock Station. The project involves track works, electrification and certain interventions to remove constraints.

DART+ West Route Map

The project covers circa 40km from Maynooth and M3 Parkway to Connolly Station and the proposed Spencer Dock Station.

Benefits of DART+ West

This project will have far reaching positive transportation effects by providing a sustainable transport system with increased passenger capacity and frequency. This will be beneficial to surrounding and future communities and will assist in reducing dependency on private cars.

Railway Order Application

The statutory application for the DART+ West project has been submitted.

Public Consultation Process

Public participation is a key element to the delivery of major infrastructure projects such as DART+ West.

More information on the Public Consultation Process

Railway Oder Application Statutory Consultation
