Welcome to the DART+ Coastal South Project

The delivery of the DART+ Coastal South project will form the fourth, and final, infrastructural project of the DART+ Programme in addition to DART+ West, DART+ South West, and DART+ Coastal North. The infrastructural interventions proposed by DART+ Coastal South will enable both an increase in passenger capacity and an increased frequency of train services on the Southern Line.

Delivery of the DART+ Coastal South project will support existing communities along the Southern Line and support future sustainable development within the Greater Dublin Area. Upon completion, the project will serve all 20 existing stations along the railway corridor between Dublin City Centre and Greystones Station, including the new station at Woodbrook, by enabling an increased frequency and improved quality of service. 

In order to deliver the infrastructure and benefits of the DART+ Coastal South project in the most efficient manner possible, the project will be delivered in 2 distinct stages, as outlined below:

• Stage 1 of DART+ Coastal South will seek to deliver the infrastructure enhancements and upgrades that will enable an increase in train frequency from 2 trains per hour to 3 trains per hour between Bray and Greystones.
• Stage 2 of DART+ Coastal South will seek to deliver the infrastructure enhancements that will enable an increase in train frequency from 6 trains per hour to 12 trains per hour between Dublin Connolly and Bray (Daly) Stations. 

In-person Events and Webinar

Your feedback on the Emerging Preferred Option is important to help shape the developing design of Stage 1 of DART+ Coastal South. Iarnród Éireann is hosting a webinar to present the emerging preferred option  and give communities along the route the opportunity to pose questions to the project team. Please see details of the events below.  

• Bray area public display, Little Flower Hall, Bray on 29th October 2025 (15:00pm to 18:30pm)
• Greystones area public display, Greystones Library on 23rd October 2025 (15:00pm to 19:00pm)
• Public Webinar, 19th November at 12:30pm to 13:30pm

To register your attendance at the webinar, please email DARTCoastalSouth@irishrail.ie confirming your interest. A link to join will be issued to you upon registration.

A clear understanding of the project status and design will help you in preparing your submission on the project. View the ways in which you can send in your submission on the How to Engage page.

DART+ Coastal South Introduction

Iarnród Éireann have now commenced with non-statutory public consultation on the Emerging Preferred Option (EPO) for DART+ Coastal South, Stage 1 Bray to Greystones Capacity Enhancements. This consultation is our way of asking you, as potential users of the service or those likely to be affected by its development, for your views. All feedback and submissions received will be reviewed and assessed as part of the design development. Following a full appraisal of the feedback, a public consultation report will be prepared to document this process. 

Stage 1: Bray to Greystones Capacity Enhancements will include:

• Railway Infrastructure modifications  to facilitate the proposed increase in service, from two to three trains per hour, between Bray (Daly) and Greystones Stations. 
• Construction of an additional crossover (track modifications to allow a train to cross from one section of track to another) just south of Bray (Daly) Station and associated modifications to reduce the length of Platform 1 at Bray (Daly) Station to 180m. These works essentially extend the length of double track within the station and allow trains to cross from one track to the other
• Proposed upgrade of Level crossing XR012 (Ennis Lane Level Crossing) at Rathdown Road to a CCTV controlled crossing to improve safety for users. Existing access across the railway will be maintained
• Undertaking upgrades to existing signalling, telecoms and power supplies to support the planned increase in train services
• Ancillary civils, drainage and power works as necessary to accommodate the project.

Your knowledge will help inform the design and help Iarnród Éireann to improve our project plans, ensuring that it will be beneficial for you and the communities it will serve.

Delivery of the DART+ Coastal South project will support existing communities along the Southern Line and support future sustainable development within the Greater Dublin Area. Upon completion, the project will serve all 1209 existing stations along the railway corridor between Dublin City Centre and Greystones Station, including the planned new station at Woodbrook, by enabling an increased frequency and improved quality of service. The project will provide a viable transport alternative to communities along the route and help encourage people to migrate from private car use to rail travel. This will assist Ireland in reducing greenhouse gas emissions from transport and help combat climate change. 

The project is predominantly located within the corridor of the existing railway and will deliver the necessary infrastructure to enable the proposed increased train capacity and higher frequency of train services associated with Stage 1 of the overall DART+ Coastal South project.
