All rail services out of Cork have been cancelled this morning due to unofficial strike action by train drivers.
A number of trains out of Dublin have also been affected.
The stoppage follows a failed attempt between unions and management to avert the action during talks yesterday.
The drivers had warned that they would not operate new inter-city trains on the Cork/Dublin and Cork/Tralee routes as part of a dispute over pay.
The strike action is also affecting the Cork/Cobh commuter route. Action by drivers based at Inchicore in Dublin has also affected a number of services out of Dublin.
A spokesperson for Iarnód Éireann says the company will not re-enter talks with the drivers until they end their stoppage and return to work.

05.30hrs Cork – Heuston
