Iarnród Éireann says it expects that services in and out of Connolly station will run as normal tomorrow after 16 services were cancelled today due to a dispute.
The 0630 service from Portlaoise to Heuston and the 1735 service from Heuston to Carlow, which have not been running since 11 February because of the dispute, will not operate tomorrow.
An escalation in the dispute between Iarnród Éireann and its train drivers led to 14 trains on Commuter and Intercity routes being cancelled today, while a further two were replaced by a bus transfer service.
Unions say the disruption has been caused by staff shortages and drivers' unwillingness to work overtime.
However, management has accused the drivers of breaching agreements.
Iarnród Éireann says drivers are refusing to carry out 'core rostered duties'.
It also says there would be no need for any work to be outside rostered hours if drivers delivered the flexibilities and efficiencies they are already being paid for.
These, it says, are separate to what is being negotiated about in ongoing talks.
The NBRU's Dermot O'Leary said today's cancellation of services was due to drivers choosing not to work on their rest days.
He said whether or not a driver chooses to work on a rest day is purely a voluntary decision for that driver.
Mr O'Leary also denied company claims that drivers are defying their own union.
He said the problem could be resolved if Iarnród Éireann management provided enough staff on the routes concerned.
But Mr O'Leary said there is huge frustration among many drivers about how long the negotiations on pay, pension and flexibilities are taking.
Iarnród Éireann has apologised to passengers for any inconvenience caused.
16 trains cancelled
Most of the disruption was in the afternoon and evening in the greater Dublin region with services to Clonsilla, Maynooth, Balbriggan and Drogheda being curtailed.
The Dublin-Sligo Intercity route was also affected with bus transfers being substituted on two services, one in each direction, this afternoon.
