Between 15,000 and 20,000 thousand commuters are experiencing major rail disruption this morning.
Iarnród Eireann says there is no DART services between Malahide, Howth and Clontarf Road.
Meanwhile, there is no Northern Commuter services between Howth Junction and Connolly.
It's caused by overhead line damage at Raheny which happened yesterday evening, but repairs couldn't start until later as people needed the service to get home from a concert in Malahide.
Barry Kenny from Iarnród Éireann says the current estimate for repairs is around lunch time.
