Iarnród Éireann has confirmed it is considering closing the Waterford to Rosslare rail line.
A spokesperson told RTÉ News this afternoon that a decision will be made within the next few weeks.
The spokesperson added that revenue only covers 2% of the cost of keeping the line open.
The line runs between Waterford city and Rosslare port, with trains stopping at towns and villages in south Wexford. It has been in operation since 1906.
There is currently a morning commuter service from Rosslare to Waterford, with a return service in the evening.
Iarnród Éireann is surveying remaining passengers regarding alternative arrangements and said that workers will be offered either a transfer or a severance package.
Wexford Labour Cllr Joe Ryan said Iarnród Éireann is failing the people of south Wexford abysmally.
He said: 'When they introduced a commuter service to Waterford from Wexford they made no effort to promote the service in the local media.
'To undermine the viability of the service, they rostered a Waterford crew on the service and as a consequence taxi bills for returning crews from Rosslare Harbour to Waterford exceeded revenues generated by the commuter service.'
