Update: The service is now operating normally.
The Luas Green Line is not in operation this morning in Dublin.
There is no tram service from St Stephen's Green to Brides Glen, but Luas tickets are valid on Dublin Bus. A Finnegans bus service also travels from Brides Glen to Sandyford.
A power failure is to blame for the outage. Luas maintenance are working to rectify the problem.
Red Line services are operating normally.
