RAIL commuters have been hit by disruption to the Dart line which has put services out of action between Dun Laoghaire and Bray since this morning.
Irish Rail said the problem was caused by a fallen tree at Dalkey which had damaged overhead power lines.
It said no services will operate between Dun Laoghaire and Bray as a result until further notice, but Dublin Bus will accept rail tickets.
Strong winds and heavy rain are battering the country, making driving conditions difficult, with snow on higher ground in some counties including Donegal and Wicklow.
However, Ireland has escaped the heavy snow which has blanketed many parts of the UK this morning.
Passengers flying to the UK have been told to check with their airlines as there may be disruption and delays.
Bristol and Heathrow have been badly affected as up to 30cm of snow fell on some parts of England and Wales.
