Major flood prevention works are set to begin in late August as part of the Waterford North Quays Development, with Iarnród Éireann confirming some off-peak morning rail services will be disrupted until early 2026.
The project, led by Waterford City and County Council, aims to tackle long-standing flooding issues on the approach to Waterford’s railway station and make the line climate-resilient. It will also support the upcoming relocation to the new Plunkett Station in 2027.
The €multi-million scheme involves the installation of a 1.1km flood defence system using sheet piled walls, impermeable trenches, and a drainage network with pumping stations. The most disruptive element—an 800-metre western flood defence wall—will be built using two barges and a piling rig operating on the River Suir.
Service disruption will occur between August 25 and November 27, 2025, and again from January 5 to March 26, 2026, on Mondays to Thursdays from 8am to 2:30pm. Key off-peak morning services between Dublin and Waterford and one from Limerick Junction will be impacted:
-
07:20 and 10:15 Dublin to Waterford services will terminate at Kilkenny, with bus transfers onwards.
-
11:00 and 13:05 Waterford to Dublin will include bus transfers to Kilkenny.
-
09:45 Limerick Junction to Waterford will terminate at Carrick-on-Suir, with a bus onward to Waterford.
Only two of the eight services each way daily on the Dublin–Waterford line will be affected during the week, and no weekend services will be impacted. Full services will operate throughout the Christmas and New Year period.
