Dublin has no subway or light rail, only one electrified heavy rail line for urban transport, called DART. Dublin also has no trolleybuses. Although there are many bus routes, they all enter the city from different directions, so there are not many that you will actually find useful. Transportation in the city center is extremely inconvenient, and walking for more than 20 minutes is unavoidable.
In terms of road infrastructure, there is not a single overpass within the Dublin city area (within the second ring road), let alone any elevated roads like those in Shanghai, Shenyang, or Guangzhou. The streets in Dublin are not wide, so traffic congestion is very serious during peak hours. Except for the Chinese, very few people ride bicycles, and there are no non-motorized vehicle lanes here. Some road sections have bicycle lanes only as wide as a handlebar, but most are set on the sidewalks.
Railways
DART (Dublin Area Rapid Transport): Until the autumn of 2000, Dublin's DART only had that one line running from south to north. In the autumn of 2000, the Dublin DART finally opened two stations on the northern second line, Malahide and Portmarnock, and expanded one station to the south—Greystones. DART trains all have green bodies. Earlier this year, Ireland introduced new models from Spain, which are more modernized than the old ones.
Suburban Rail (Chinese name: Big Red Train): Suburban rail lines that do not serve DART areas, with red bodies and extremely high noise levels!
Arrow: Western suburban rail line. Since it departs from the West Station, it does not use the name Suburban Rail, but the trains used are no different from the Suburban Rail.
Buses
Dublin Bus (Routes 1-89): Standard buses, all double-deckers, mostly entering the city from different directions.
Rail links (Routes 90, 91): Bus lines connecting Dublin's West and East train stations.
Suburban Rail links (Routes 100-119): Bus lines connecting different suburban towns with rail lines.
Mini Bus/City links (Routes 120-160): These are small buses, and there are also long single-deck buses.
Air links (Routes 746, 747, 748): Bus lines connecting to the airport. (Note: Since Dublin Airport is not far from the city center, regular Dublin Bus routes can also get you there. Moreover, Air links tickets are expensive and not necessarily faster, as they also stop at every stop, so there is no reason to take them. (Also recommended to visit: Ireland Bus Company website))
Taxis
The starting price for a taxi is 1.9 pounds, excluding mileage, with 10p per 100 meters (i.e., 1 pound per kilometer). Taxis here charge a per-person fee of 40p. Extra luggage is also counted as a person.
Water Transport
Water transport within the city has been abolished.
