Public transport in Ireland
Public transport in Ireland exists in many of the island's urban areas, and takes a number of forms. Bus transport is the main form of public transport common in all cities. The cities, Dublin, Cork, Limerick and Galway all have their own suburban rail networks. Ireland has a population of over 6.4 million people.
Transport for Ireland is a public information body set up by the National Transport Authority as a single point of reference for all public transport in Ireland, along the lines of Transport for London.
Provision by area
The Greater Dublin area has a population of 1.7m and there are a number of modes of public transport in the GDA run by a number of transport operators, most of them state or quasi-state entities. Public transport in Dublin is overseen by the National Transport Authority. It has undergone expansion in recent years, and the Irish Government plans to invest heavily in the system under the Transport 21 plan which means that approximately 20 billion euro will be spent on developing Greater Dublin's transport infrastructure. Dublin's transit system utilises electrified suburban trains, diesel commuter rail, trams and an extensive bus network to provide service to the population of the Greater Dublin Area.
Buses are the most widely used form of public transport in Dublin. They are operated by Dublin Bus. The bus network consists of 200 bus routes covering the Dublin Region. The Bus Arrival Information Service is being rolled out across Dublin, and provides real time estimates of bus arrivals at each stop, based on GPS locations of buses.
Dublin also has a commuter rail system, one of five suburban rail networks on the island. The system uses diesel-powered trains and an electrified line. There are four main lines, designated Northern Commuter, Western Commuter, South Eastern Commuter, and South Western Commuter. The trains are operated by Iarnród Éireann.
The Dublin suburban network also consists of an electrified line Dublin Area Rapid Transit that serves the Dublin bay commuter belt.
- Northern Commuter – Dublin Pearse to Dundalk.
- South Eastern Commuter – Dublin Connolly to Wexford/Rosslare Europort.
- South Western Commuter – Dublin Heuston to Kildare.
- Western Commuter – Dublin Pearse / Docklands to Longford.
- Dublin Area Rapid Transit (DART) – Greystones to Howth/Malahide.
There is also a tram network called LUAS consisting of two lines;
As of 2006, the Dublin Metro is a planned two-line rapid transit (underground) system set out in the Irish government's 2005 Transport 21 plan to spend 20 billion euro on infrastructure in the Greater Dublin area up until 2021. The estimated cost of the 17km Metro North is approximately 5 billion euro and will be the biggest and most expensive infrastructural project ever undertaken on the island of Ireland.
