7 sets are needed every week day to maintain the schedule. 8 full sets are available, with 3 additional carriages available.

However, as two morning services are operated by 22000s, 2 of the 7 sets only need to do one return trip, while the other 5 do two return trips every day.
Assuming that the eighth set is in deep maintenance, it is very difficult for to arrange for a longer set to be used on the morning peak to Dublin and the evening peak to Cork.
