Transport Minister Seamus Brennan has said the rail track and viaduct damaged in an accident on the Waterford to Limerick Junction line this morning will be repaired and put back in service.
He said the line would be closed for some months for repair, but he was committed to the rail network and would not allow the closure of any rail line.
He said he believed freight should be taken off the roads and put on the rail and he reminded the Dáil that he had refused permission to Iarnród Éireann when they wanted to reduce their freight service in the past.
An investigation has begun following the derailment of a freight train that resulted in the collapse near Cahir in Co Tipperary this morning.
The train, which was carrying cement, was en route to Waterford from Limerick Junction when the derailment occurred at around 6am.
The train consisted of two locomotives and 22 bulk cement wagons. Two locomotives and nine wagons remained on the track, however, 13 wagons derailed at the viaduct.
The centre section of the rail bridge known as the Cahir viaduct completely collapsed. There are fears that pollution of the river may occur because of the cement.
Iarnród Éireann says the driver was not injured and the line will be closed for some time because of structural damage.
Bus transfers will be arranged on the route for passenger services. Alternative arrangements are also being put in place for freight customers.
