Public transport in Ireland exists in many of the Ireland's urban areas and rural areas, and takes a number of forms. Bus transport is the main form of public transport and is common in all cities. The cities, Dublin, Belfast, Cork, Limerick and Galway all have their own suburban rail networks, although Dublin is the only to have its own tram line, in the form of the Luas. Ireland has a population of 5 million people.
In 2021, the Irish government released the climate action plan. This sees two brand new Dart (Tram/Train) lines west and south of Dublin, Ireland's first underground metro (Metrolink), a brand new electric train fleet delivered by Alstrom, extension to Luas (Tram) to North Dublin Finglas and more funding for Ireland's rural transport, Local Link.
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. TFI (Transport for Ireland) has a travel card available to its service users and tourists. It offers much cheaper transport fares compared to cash.
