Normal rail services could return by Monday if the Irish Locomotive Drivers' Association (ILDA) co-operates with the proposed investigation into the 56-day dispute, an Iarnrod Eireann spokesman said last night.
Mr Barry Kenny said Iarnrod Eireann remained prepared to take part in the investigation into the ongoing dispute by the Labour Relations Commission.
The Dublin-to-Cork route will be serviced by four trains today, with three travelling the return route. Four trains will run between Dublin and Tralee while only one will travel from Tralee to Dublin.
Six trains are scheduled to travel the Dublin-to-Limerick route and five will service the return route. Four trains will travel from Dublin to Sligo, and three from Sligo to Dublin. Waterford will have a full service, with four trains each way.
Two trains will operate in each direction between Dublin and Westport, all of them involving a bus transfer for passengers. Passengers from Westport and Castlebar will travel by bus to and from Claremorris while Ballina and Foxford passengers will change trains in Claremorris to connect with the Ballina shuttle service. The Cork/Cobh service will be supplemented by buses at peak times.
There will be more disruption to the Drogheda/Dundalk services, which will continue to run at about two-thirds of normal levels, while the Kildare Arrow will operate at less than half normal services.
Galway, Rosslare and Belfast will have a full service and the DART, Maynooth and Arklow services are expected to operate as usual. Tomorrow's service will operate at a reduced level in Cork, Limerick and Westport.
