There has been severe disruption to rail services for a second day today as a result of continuing unofficial action by train drivers that left up to 35,000 passengers stranded yesterday.
The dispute is over the introduction by the company of a new high-tech train it had planned to bring into service on a trial basis yesterday.
Two Cork-based drivers refused to operate the new train and drivers based in Cork, Limerick and Dublin stopped work in support of their two colleagues.
Iarnród Éireann has warned that there will be no Intercity services to and from Cork, Galway, Mayo, Kerry and Limerick. There will be no Commuter services to and from Portlaoise and Kildare or on the Cork - Cobh commuter route, although some local Limerick services may operate.

There may be some services between Waterford and Dublin.
Dart services and commuter trains between Dublin, Dundalk and Drogheda, along with services to Maynooth, Sligo, Belfast, Gorey, Arklow and Rosslare, are expected to operate normally. Services to and from Connolly station in Dublin have not been affected.
Iarnród Éireann strongly urges intending passengers gers to check the company's website or ring the information line on 1850 366 222 in advance.
There were no indications last night that an early resolution to the dispute was likely, with the company insisting that it would not negotiate with staff engaged in unofficial action.
A spokeswoman for Iarnród Éireann told ireland.comthat the dispute will affect 35,000 passengers per day and "due to the unofficial nature it is difficult to say if there is an end in sight." However she went on to say that senior trade union officials are meeting with drivers' representatives this morning.
Iarnród Éireann is seeking to introduce a new generation of trains, known as the "Mark Four", as part of a €117 million investment in its rolling stock. Siptu and the National Bus and Rail Union sought a pay increase of 5 per cent for drivers, and a reduction in working hours, in return for the introduction of the new trains as well as other work changes.
