thanks for the info sublimity.
I hope this mess will get sorted soon, Its really a pain to complain to Irish Rail about the same issue over an over again, I actually complained so often that my e-mails were answered by the Customer Service Manager for the Northern Line. Thats were I got the info with the shortage and the high utilization rate of carriages in a lengthy e-mail in October last year.
So where are these "extra" carriages are they standing idle or are they used in other trains? The thing is sometimes there is a 3-set train on the 6.30 am Rosslare line for 1 or 2 days then its gone (Some weeks ago it was nearly every day of the week when we got 3-train set, only recently it has turned i a complete bummer again). I guess some stock breaks down and is in repair, but then there definitely is a need to get more carriages if thats the point.
I wish more people would complain about it (they do on the train for sure but then don't seem follow up with e-mail, customer service hotline etc, might work
)
