This sortable table lists railway accidents in the Republic of Ireland, and before its formation accidents in the provinces of Leinster, Munster and Connacht, plus the counties of Donegal, Cavan and Monaghan. It is currently limited to accidents where at least one train occupant was killed. It does not include acts of terror, nor accidents in Northern Ireland.
The 'TRA link' column gives a link to the accident's page on The Railways Archive web site, though some may not yet be fully detailed.
