I'm not aware of any changes.
Cork-Hazelhatch is still routing via Heuston for many trips.
A few things may have happened:
* the timetable changes have reduced the connection time below what is practical / reasonable. Note that intermediate times can be quite tight, as they put the padding at the end of the timing.
* they have increased the connection time setting in the journey planner.
The connection time is there to allow for trains being late and to get from one platform to another (more important in the likes of Connolly than Thurles).
