Overhead power line problems lead to major disruption during Friday rush hour
There are further headaches for Dublin commuters this evening as northbound DART trains are suspended in major areas of service.
All trains are suspended between Harmonstown and Howth and Malahide, while a limited service is running between Connolly and Harmonstown.
The problems are due to an overhead fault line.
No Luas trams are running today as it is the second day of a 48 hour strike.
The strike has seen heavier than normal traffic volumes in Dublin city center, with packed buses and trains, as commuters made alternative arrangements.
A further 48-hour stoppage is planned for next Thursday and Friday.
