Irish Rail is rejecting newspaper reports that it had been warned about erosion at the Malahide viaduct as far back as 2006.

Catastrophe was narrowly averted at the estuary bridge last summer, when a train driver spotted that the track ahead had been washed away.

Repair work led to disruption on the Belfast to Dublin rail line for a number of months.

Iarnrod Eireann has released details of a report into the incident today – and says its already taking action on the recommendations,  including the installation of a bridge monitoring system on the Malahide Viaduct.
