The DART line between Bray and Greystones in County Wicklow will be closed for the day after a fire.
Signalling and telecoms cables were damaged when flames spread from a tent pitched away from the tracks. The fire started in front of a tent and spread along steep ground east of the cliff walk at around 1 am this morning.
Irish Rail's Barry Kenny has said Dublin Bus will accept valid tickets until the line re-opens to passenger.
