The first phase of the extended light rail project approved by Government includes two lines: Tallaght to Connolly Station and Sandyford to Ballymun and Dublin Airport. These do not include any connection to the location of the proposed new Arena stadium.
The two lines are the first phase of a longer term vision for an extended light rail network serving destinations such as Swords, Docklands, Cabinteely, Clondalkin and Finglas.
The question of further extending the light rail network is among the matters currently being considered by the Dublin Transporation Office as part of its work on the updating of the DTI Strategy.
