There were major delays on all services to and from Heuston Station on Wednesday morning.
This was due to vandalism overnight.
Signalling systems were damaged as a result of the vandalism.
Update: Signalling issues have now been rectified. Delays into Heuston up to 50 minutes remain due to congestion of incoming services. These are expected to ease throughout the morning https://t.co/ovXuSXx30f— Iarnród Éireann (@IrishRail) October 9, 2019
