Knock-on delays are expected for commuters this morning to DART and commuter services following damage to an overhead power line fault at Clontarf road that has just been rectified.
The disruption saw DART services only operating between Howth/Malahide and Killester, and between Connolly and Bray/Greystones only.
However, Irish Rail said that the fault has been rectified and services are set to resume with delays due to congestion and operational issues.
Additionally, Bus Éireann has announced that its call centre phone lines are currently down.
Customers with inquiries are advised to email the company or contact them via direct messaging on social media.
Merrion Row is also now closed to traffic until approximately 11pm on Wednesday due to Gas Networks Ireland carrying out essential works.
Traffic is being diverted to Hume Street and Ely Place.
