Most of the transport system in Ireland is in public hands, either side of the Irish border. The Irish road network has evolved separately in the two jurisdictions into which Ireland is divided, while the Irish rail network was mostly created prior to the partition of Ireland.
The Dublin Area Rapid Transit system is an electrified commuter rail railway network serving the coastline and city of Dublin, Ireland. The service makes up the core of Dublin's suburban railway network, stretching from Greystones, County Wicklow, in the south to Howth and Malahide in north County Dublin. The DART serves 31 stations and consists of 53 route kilometres of electrified railway, and carries in the region of 20 million passengers per year. In a similar manner to the Berlin S-Bahn, the DART blends elements of a commuter rail service and a rapid transit system.
Córas Iompair Éireann, or CIÉ, is a statutory corporation of the Republic of Ireland, answerable to the Irish Government and responsible for most public transport within the Republic and jointly with its Northern Ireland counterpart, the Northern Ireland Transport Holding Company, for the railway service between Dublin and Belfast, via Drogheda, Dundalk, Newry and Portadown. The company is headquartered at Heuston Station, Dublin. It is a statutory corporation whose members are appointed by the Minister for Transport.
The history of rail transport in Ireland began only a decade later than that of Great Britain. By its peak in 1920, Ireland had 3,500 route miles (5,630 km). The current status is less than half that amount, with a large unserviced area around the border area between Northern Ireland and the Republic of Ireland.
Rail transport in Ireland is provided by Iarnród Éireann in the Republic of Ireland and by Northern Ireland Railways in Northern Ireland.
Iarnród Éireann, or Irish Rail, is the operator of the national railway network of Ireland. Established on 2 February 1987, it is a subsidiary of Córas Iompair Éireann (CIÉ). It operates all internal InterCity, Commuter, DART and freight railway services in the Republic of Ireland, and, jointly with Northern Ireland Railways, the Enterprise service between Dublin and Belfast. In 2019, IÉ carried a record peak of 50 million passengers, up from 48 million in 2018.
National Development Plan is the title given by the Irish Government to a scheme of organised large-scale expenditure on (mainly) national infrastructure. The first five-year plan ran from 1988 to 1993, the second was a six-year plan from 1994 to 1999 and the third ran as a seven-year plan from 2000 to 2006. A fourth National Development Plan ran from 2007 to 2011. The main elements of the third plan were the development of a national motorway network between the major cities in Ireland. The upgrading of the rail network was a secondary scheme.
Luas is a tram system in Dublin, Ireland. There are two main lines: the Green Line, which began operating on 30 June 2004, and the Red Line which opened on 26 September 2004. Since then, the red line has been extended and split into different branches further out of the city and the green line has been extended north and south as a single line. Since the northern extension of the green line in 2017, the two lines intersect in the city centre. The system now has 67 stops and 42.5 kilometres (26.4 mi) of revenue track, which in 2023 carried 48.2 million passengers, an increase of 24% compared to 2022.
Connolly station or Dublin Connolly is the busiest railway station in Dublin and Ireland, and is a focal point in the Irish route network. On the North side of the River Liffey, it provides InterCity, Enterprise and commuter services to the north, north-west, south-east and south-west. The north–south Dublin Area Rapid Transit (DART) and Luas red line light rail services also pass through the station. The station offices are the headquarters of Irish Rail, Iarnród Éireann. Opened in 1844 as Dublin Station, the ornate facade has a distinctive Italianate tower at its centre.
Transport 21 was an Irish infrastructure plan, announced in November 2005. Its aims were to greatly expand Ireland's transport network. A cost estimate of €34 billion was attached to the plan at the time.
Many companies operate public transport services in Dublin, most of which are state-owned or semi-state-owned.
The Dublin Suburban Rail network, branded as Commuter, is a railway network that serves the city of Dublin, Ireland, most of the Greater Dublin Area and outlying towns. The system is made up of five lines:
The Cork Suburban Rail network serves areas in and around Cork city in Ireland.
The Belfast suburban rail commuter network serves the metropolitan area of Greater Belfast and some of its commuter towns with three lines. The network is owned by Translink and operated by its subsidiary NI Railways.
InterCity is the brand name given to rail services operated by Iarnród Éireann that run between Dublin and other major cities in Ireland. InterCity branding is also used in other European countries by unaffiliated organizations.
Commuter is a brand of suburban rail services operated by Iarnród Éireann in the Republic of Ireland, serving the cities of Dublin, Cork, Limerick and Galway. This brand is distinct from the longer distance InterCity brand, and Dublin's higher frequency DART brand. Most Commuter services share a track with InterCity services. During the first decade of the new millennium, Iarnród Éireann put a significant amount of effort into upgrading its network, with new tracks, signalling, station upgrades and trains. Commuter services are operated by diesel multiple unit train sets.
This article deals with transport in the Greater Dublin Area centred on the city of Dublin in Ireland.
The Dublin–Cork Main Line is the main InterCity railway route in Ireland between Dublin Heuston and Cork Kent. In 2018, 3.46 million passengers travelled on the line, a 10% increase from 2017 figures.
The Dublin–Belfast corridor is a term used to loosely describe a geographical area that encompasses the Republic of Ireland's capital city, Dublin and Northern Ireland's capital city, Belfast. It also includes the smaller cities of Lisburn and Newry; major towns such as Drogheda and Dundalk; and the Dublin satellite suburb of Swords. The term has been used in papers regarding planning strategies in the area, with the aim of capitalising on the expanding economies of both cities. Since the implementation of Brexit, the corridor exists inside the European Union on its Republic of Ireland side, and outside the European Union on its Northern Ireland side, but there is no so-called "hard border" between the two states.
Since the early 2000s, a number of proposals have been made by politicians and interest groups in Cork City, Ireland to introduce a light rail system in the city. As of early 2019 it was in a period of public consultation. The proposal, which has "no definitive timeline", has been compared to the Luas light rail system in Dublin.
