Further disruption is expected on the Irish rail network today as approximately 100 ATGWU train drivers enter day two of their strike.
The pickets move to Heuston Station today, with all inter-city routes into the station due to be affected.
The stoppage will halt services in Munster region of the country, with no trains operating to the south west.
Commuter services to Kildare, Portlaoise, Carlow and Athlone will also be badly hit. Services to and from Connolly Station, which were hit yesterday, are due to return to normal.
Talks aimed at resolving the row are expected tomorrow, involving the Irish Congress of Trade Unions, which is opposed to the strike action.
Irish Rail claims the stoppages are the result of inter-union divisions.
