We are planning on taking the train from Sligo to Dublin in order to catch a flight the same day. The schedule seems perfect. But I've seen comments on some websites that Irish trains are frequently late, but it's not clear how late. Is the train a reliable way to get to Dublin if we absolutely have to make a flight? Thanks.
The official punctuality statistics for that route for 2012 are here: http://www.irishrail.ie/index.jsp?p=265&n=266#sligo It shows the percentage of trains which arrived on time, or within 10 minutes of their scheduled arrival time. Not sure how much help it would be to know that 95% of trains are punctual if you happen to be on one that is late, but there it is.
That looks encouraging, thanks. A few minutes late would be OK; we have about a half hour to spare. In the US, trains are often hours late, and that would be a problem.
