That ICR set is meant to be on the 5:55 Gorey Dublin service but due a rostering change due engineering works it finds itself in the wrong place. Some of the first of the new ICR's are destined for Sligo and Rosslare
The ICR catering offering is not great but equally demand is not great either the current trolley offering does offer full bar service as well which previously was not the case. Even on trains with full catering take up is low.
For the record I have been served hot food on a Sligo standard class 3 coach ICR, so it is possible.
And the price of hot food goes down on the train tomorrow
two weeks late but any reduction is welcome
