DART and Luas services were severely disrupted by a car crash and a fallen tree.
DART services in South Dublin were disrupted when a tree crashed onto power lines at Dalkey in the early hours of this morning. Repair crews worked through the night to fix extensive damage but morning services were unable to begin today.
There were no early DARTs from Dun Laoghaire to Bray.
The collision involving a Luas tram and a car happened at the junction of Jervis Street and Upper Abbey Street this morning. No one was injured but trams were halted for more than 20 minutes.
