There had been no tram services between Abbey Street and The Point since May to facilitate Luas Cross City works
Full service on the Luas Red Line resumes today.
It follows a partial line closure to facilitate Luas Cross City works in recent months.
A temporary bus service had been in place following the closure of the stops between Abbey Street and The Point.
The tram service is now fully operational from Tallaght/Saggart to The Point.
The Luas Cross City service will extend the Green Line to link St Stephens Green and Cabra, as well as creating an interchange with the Red Line.
It is expected to be in operation by the end of 2017.
