Dublin Connolly Railway Station provides intercity and commuter services to the north, northwest and south of the country. The north-south Dublin Area Rapid Transit (DART) service also passes through the station.
There are two intercity train hubs in Dublin, Connolly Station in the city centre and Heuston Station in Dublin 8. Connolly Station (which is on the DART and suburban lines) seves the north (Belfast) and northwest (Sligo) routes, while you’ll depart from Heuston to go west to Mayo or central Galway, or south to Limerick, Cork city centre, or Waterford.
Connolly and Heuston aren’t connected to each other by rail. That problem is being dealt with by the new Luas system, but in the mean time the Railink bus joins the two stations via Bus Áras, the regional bus hub.
Routes serviced: Dublin – Sligo; Dublin – Belfast; Dublin – Rosslare Europort; Dundalk – Dublin – Arklow; Dublin – Maynooth – Longford; D.A.R.T. Malahide/Howth – Greystones.
The rail station is also connected by bus to the Port of Dublin, where Stena Line ferries leave from the Ferry Terminal to Holyhead in Wales.
