Dublin Heuston, commonly called Heuston station, is located in Dublin, Ireland is one of the country's main railway stations, serving the south, southwest and west of Ireland. It is the main railway station for the south. The station is operated by Iarnród Éireann, the national railway operator in the Republic of Ireland, with the main offices of the railway company located in the station building. The station is also the head office of Iarnród Éireann's parent company, Coras Iompair Éireann. The main maintenance depot, at Inchicore, is located approximately two miles from the station. The station is connected to Connolly Station by the Red Line of the Luas light rail system. As this system is built to a different gauge, through running is not possible. There is a physical rail link between the two stations via Islandbridge Junction (less than a mile from Dublin Heuston) but this is usually only used for freight and rolling stock movements — once or twice a year special trains may operate, usually from Cork to Connolly for GAA matches in Croke Park.
