IRISH RAIL is advising passengers that services in and out of Heuston Station in Dublin will face significant delays this morning as a result of overnight vandalism as well as the heavy rain.
It is understood that signalling cables were stolen from an area on the line between Kildare and Newbridge overnight.
The damage has now been repaired, but delays will continue for some time until the backlog of services has been cleared.
The overnight heavy rain has also contributed to delays on many lines in and out of the capital.
Services in and out of Heuston are likely to experience delays of between 30 and 50 minutes, with delays fluctuating for individual routes, for some time this morning.
Passengers can access live updates of expected delays through the appropriate page on the Irish Rail website.
A spokeswoman for Irish Rail said engineers were working to resolve the problems but that the delays were expected to continue for the rest of the morning.
It is understood that Gardaí are investigating the circumstances of the disruption.
