To travel within Dublin City, you can use public transport. There are 3 parts to this system: buses, trains and trams. A plan to integrate the tickets between each of these will be implemented by 2010.
Buses
Dublin Bus provides bus services for the city and county of Dublin and adjoining areas. Many other private bus companies also offer transport in and out of the city.
Trains
A frequent train service called DART runs along the coast of Dublin, from Malahide and Howth in north Dublin to to Greystones in the south.
Other train services from Irish Rail connect Dublin city with suburbs in the west, north and south.
Trams
A frequent tram service called LUAS connects Dublin city centre with suburbs in the south and south-west of the city.
