Northside Dart services to and from Tara Street station in Dublin are back to normal this morning after overnight work to repair overhead line damage.
Northbound Dart passengers were left without a full service from 4.40pm yesterday. Although services were restored from Killester onwards, Iarnród Éireann later suspended all northbound Dart services from 8.45pm last night.
It said this was to allow staff time to repair the overhead line damage and to ensure normal services this morning.
Earlier, northern commuter rail services were also badly disrupted during the peak rush hour period. Iarnród Éireann estimated that some 10,000 passengers were affected.
All northern commuter and northside Dart services had initially been curtailed due to damage to the overhead power lines north of Connolly station, where a Dart was also blocking lines.
However, some commuter services were restored, with delays.
