Irish Rail is definitely something to write home about! Clean, comfortable, reliable, and on time. It accesses all the major cities in Ireland.
If you’re coming to Ireland (for this year’s Gathering perhaps) all you need to do is go online to irishrail.ie to book your train tickets. You’ll pick your tickets up when you get to the station by entering your reservation number into a kiosk. The find the train platform and take your seat. There are food, restrooms, and free (but intermittent) wi-fi access on board.
Simple as pie!
