Well... the bus will have to do then. The citylink for instance has a non stop service. It is quicker than the train to be honest. Often it is a double decker with toilet as well. Could always get the train there (so you can drink if you like) and then bus home. That said, I think the last one is 7pm <!-- s:? --><img src="{SMILIES_PATH}/icon_confused.gif" alt="

Irish rail is bloody useless I have to say. I don't care if they make a loss at certain times, they are a state company and should be providing a proper service regardless.
It is ridiculous that you can't get from Dublin to Mullingar by train after 7pm on a weekday.
Anyway it does not even have to be as far afield as Galway. We could go closer to home as well but Galway does have a lot to offer the craft beer drinker.
