Dart services between Dún Laoghaire and Bray have resumed after being suspended due to flooding on the line caused by heavy rainfall.
Iarnród Éireann said full services on the southside were resuming after the Dún Laoghaire and Bray line was shut shortly after 1pm on Saturday.
The flooding also resulted in a limited service between Dún Laoghaire and Pearse St station.
Iarnród Éireann warned intending passengers to expect delays as services returned but said these should ease over the afternoon.
A rainfall warning is in place for Leinster and counties Cavan and Monaghan until 3pm with Met Eireann warning of heavy and thundery downpours which may lead to accumulations of 20-30mm.
There is also a rainfall warning in place for Donegal until 6pm on Saturday.
