faces a full shutdown of train services between Sligo and Dublin today, Tuesday
Fourteen services between the two centres will likely be affected.
It is the second day in a series of five planned national stoppages.
Bu the prospect of a longer strike — hitting Christmas peak — is also on the cards if there is no solution.
Both unions, SIPTU and the National Rail and Bus Workers Union, support today’s second stoppage.
Unions members want an annual pay increase of about 3.75 per cent.
This figure is similar to the increase secured by workers at both Dublin Bus and Luas after strikes last year.
Last week, Iarnrod Eireann guesstimated that €900,000 could be lost nationwide in revenue in each of the 24-hour stoppages.
Staff were warned, too, that their individual losses could be over €1,200 if the series of one day strikes proceed.
To date, Iarnrod Eireann has offered a 1.75 per cent increase for one year.
In return the company is seeking performance management and absenteeism management.
Also sought from workers are revisions to redeployment policy and payroll.
Today’s pickets today will close all inter city and Dublin suburban train services.
The DART train service will not operate either, the company has advised passengers.
Following today's action trains - along with DART and commuter routes - are not expected to operate on the following dates:
Tuesday, November 14
Thursday, November 23
Friday, December 8
Union chiefs are also understood to be prepared to call strike days for December 23 and 24. causing havoc and misery for Christmas commuters.
Speaking yesterday evening Transport Minister Shane Ross said: “I sincerely call on all parties to the Iarnród Éireann pay dispute to continue to use the services of the Labour Court and the WRC. It is vital for the travelling public – and also for the staff and for the company itself – that public transport is sustained, and that the dispute is resolved in a realistic, fair and workable manner”.
