Emergency services attended the scene
The Luas Red Line in Dublin has re-opened following earlier disruption.
It is believed a male pedestrian was injured after being struck by a tram shortly before 2.00pm on Stephen's Lane.
The tram was travelling from Tallaght to the city centre.
Emergency services attended the scene, and the man was taken to hospital.
His condition is not known.
Luas say delays are to be expected for a period to allow for regulation of the line.
However tickets are valid on Dublin Bus for the duration.
All Green Line services are operating normally.
