Irish Rail says more than 50 extra trains will operate during the celebrations in Wexford town.
An extra Connolly to Wexford train will run every day between Tuesday 6th and Sunday 11th of August.
However, the line between Wexford and Rosslare will be closed for the duration of the event.
Bus transfers will operate between Enniscorthy, Wexford, and Rosslare on all regular services between the 4th and 11th of August (except the 05:50 Gorey to Connolly from 6th to 9th August)
There'll also be shuttle buses and extra trains between Arklow and Wexford.
