Irish Rail Dart and commuter services are operating with delays of up to 40 minutes in south Dublin due to a signalling issue on Tuesday morning.
The company said the signalling issue is between Shankill and Killiney. “Knock-on delays can be expected as a result of congestion on the line,” it said.
Separately, the 7.45am Bray-Howth service was cancelled due to “operational issues”.
On Monday morning Dart services were delayed by up to 25 minutes due to a vehicle hitting a level crossing.
