Dublin Suburban Rail - Northern Commuter - D

• Northern Commuter - Dublin Pearse to Dundalk (with one peak time train to Dublin in the morning and an evening train back to Newry) every weekday.
• South Eastern Commuter - Dublin Connolly to Gorey.
• South Western Commuter - Dublin Heuston to Portlaoise/Newbridge. Grand Canal Dock to Hazelhatch and Celbridge/Newbridge via the Phoenix Park Tunnel.
• Western Commuter - Dublin Pearse / Docklands to Longford/M3 Parkway.
• Dublin Area Rapid Transit (DART) - Bray Daly/Greystones to Howth/Malahide.

Northern Commuter Stations Served:

• Dublin Pearse, Tara Street, Dublin Connolly, Howth Junction, Clongriffin, Portmarnock, Malahide, Donabate, Rush and Lusk, Skerries, Balbriggan, Gormanston, Laytown, Drogheda, Dundalk and Newry (limited service).
• Dunleer and/or Dundalk South have been mooted as possible additional stations. The track is shared with the Dublin - Belfast Enterprise service, and DART services as far as Malahide. The bridge at Drogheda is a single track that may hinder high-frequency services in the long term. The halt at Mosney is no longer used due to the closure of the holiday camp there.

Iarnród Éireann envisaged electrification as far as Drogheda by 2030, with the stations between Drogheda and Malahide incorporated into a new DART service between Drogheda and Hazelhatch and Celbridge by 2022.
