Services have resumed on all of the Luas green line following major disruption earlier today.
Trams are now serving all stops along the line, which extends from Broombridge in west Dublin to Brides Glen on the southside.
Operators have said there will may be minor delays as services return to normal.
The disruption was caused by a technical fault on the line's overhead power lines which was discovered overnight.
The Luas red line was not affected by the fault.
