Due to ongoing industrial relations issues there is a strong possibilty that there may be cancellations on some services. These will be ad hoc and random in nature and it is unlikely we will have details before they occur.
Trains effected most likely are those which where added in the new timetable and some others. This would indicate a refusal by staff to undertake work as overtime or a lack of cover due to staff calling in sick.
The perliminary best guesses are as follows
06:30 Portlaois - Heuston
17:35 Heuston - Carlow
19:30 Cork - Cobh
20:00 Cobh - Cork
20:30 Cork - Cobh
21:00 Cobh - Cork
