I looked at the main site and only DUB-Belfast had prices 19 euro standard and 61 first-class. WHen I typed in others like DUB-Cork or DUB to Galway it doesn't give me the prices. Anyone have a guess? I'm trying to gauge whether it's cheaper to buy a rail pass versus individual tickets. Thanks!
The Irish Rail website will only sell tickets & shows prices for trains 2-months ahead. Right now, it's only showing ticket prices for trips from now until Nov. 17th. Try doing a search for next week or month to get an idea of ticket prices. A railpass is rarely worth it for most travelers in Ireland. Most likely, just buying individual tickets will be your best bet.
