Place & story
Stone piers across the estuary
At Malahide’s northern edge, the railway crosses Broadmeadow Estuary towards Donabate. The Dictionary of Irish Architects records Marcus Harty’s replacement viaduct of 1860–61, with stone piers and iron spans, succeeding an earlier structure of the 1840s. William Anderson supplied the ironwork through Courtney and Stephens of Dublin. Concrete spans subsequently replaced the iron ones. [2]
The collapse of 2009
On 21 August 2009, a train driver saw the viaduct beginning to fail and alerted the signalman. Signals were set to stop further trains before Pier 4 collapsed into the estuary. Nobody was killed or injured. The Railway Accident Investigation Unit identified erosion around the supporting weir as the immediate cause, alongside failures in inspection, maintenance and the retention of engineering knowledge. [3]
Rebuilding below the waterline
The investigation’s account of reconstruction records twenty-two steel piles supporting the rebuilt pier. Additional piles strengthened the other piers and abutments, while two replacement spans carried the reinstated track. Repairs therefore addressed the foundations as well as the conspicuous gap above the water. [3]
