The fare charged at the booking office is valid for the distance category but is taken from the wrong fare matrix. The ticket machine in Thurles is using the default matrix and not the discounted economy 2 fare.
This could be down to
1. Machine programmed wrong
2. Clerk using the express ticket code and not the econ 2 code when issuing
Check the TVM, it tends to be more accurate
All routings from the south Tipperary line are via Waterford or Limerick Junction
The fare calculator on the RUI site reflects all non standard routings in use by Irish Rail at this time
The Waterford - Mallow via Fermoy routing was deleted without notice by Irish Rail in December 2012, our results reflect this after asking Irish Rail management to confirm the routing rules. We can add/remove a station or routing in a few seconds, while Irish Rail have to manually edit a huge text file.
