Talks to end the Irish Rail strike are underway at the Labour Court this morning.
Unions and management have been invited to try to end the pay dispute.
Irish Rail have said they hope negotiations will lead to a calling off of three further planned strike days but unions say they're not optimistic today will provide a breakthrough.
Workers at Irish Rail want a pay rise of 3.75% a year for the next three years, but management say that's not sustainable.
Instead, they've offered a 1.75% rise this year and negotiations on any further increases.
The unions want a no strings attached deal, arguing they haven't had a pay rise in almost 10 years. However, management want productivity and roster changes in exchange for the increase.
The next strike is planned for Tuesday 14th November.
