Rail line closed for three months

The damage was spotted by a train driver

Irish transport company Iarnród Éireann is to provide extra buses on Monday for passengers affected by the damage on part of the Belfast-Dublin rail line.

Up to 10,000 passengers daily are facing disruption after a section of the line near Malahide collapsed.

The company expects the line to be closed for up to three months.

Belfast Enterprise services to Dublin are running with passengers being transferred by bus between Drogheda and Connolly Station in Dublin.

A train driver spotted subsidence on the line while his train crossed the viaduct across the Broadmeadow Estuary near Malahide in north County Dublin on Monday.

He managed to reach Malahide Station and report the incident, but a 20-metre section of the line collapsed into the water a short time later.
