Plans for a new DART line to Celbridge have been revealed.
The project will extend DART trains from Dublin city centre to Hazelhatch and Celbridge train station in Co Kildare, as part of a wider expansion of DART services.
It involved 20 kilometres of a new electrified track and the project will move into the planning system by the end of the month.
Subject to planning permission and funding, work could begin in 2025.
