Train passengers are experiencing further disruption today because of an unofficial dispute by Cork-based train drivers.
In a statement, Iarnród Éireann says the dispute is causing significant disruption to services in the Cork and Kerry areas.
Some 22 trains on the Dublin to Cork and Kerry routes have been cancelled.
There are no train services running between Cork, Cobh, Mallow and Tralee. A bus service is operating in these areas.
Iarnród Éireann said that Galway and Westport line services would operate normally today.
Up to 20,000 passengers were affected by yesterday's disruption, as a row between Iarnród Éireann and Cork-based train drivers spread to the west of Ireland.
The stoppage began on Thursday after a Cork-based driver was taken off the payroll, after he refused to work his roster when asked to drive a train being used to instruct new recruits.
Other drivers then walked off the job in sympathy.
Iarnród Éireann says 30 trains between Dublin, Cork, Galway, Westport and Athlone were cancelled.
Cork commuter routes were also affected.
Shop stewards from the National Bus and Railworkers' Union submitted proposals to return to work.
However the company describes the offer as an unconditional return to work with conditions.
It says the drivers have already agreed and been paid for the duties asked of them.
Passengers are being advised to check the Iarnród Éireann website for full details of the affected services.
