We have asked for details to be made public, though I'd guess the fares are only being finalised this week. The list doesn't match with Irish Rail's family of ticket options.
If the staff in Limerick are asking their ticket machine it is likely to be wrong. If the day return fare Limerick Sixmilebridge is really 11 euro we might was well give up
If I was a betting man I'd try the ticket vending machine in Limerick on Saturday morning, it will get a software update on Friday which might reveal the truth
Based on IE's numbers its clearly zone B to Sixmilebridge, the maximum approved fares are taking a zone B distance journey elsewhere
