I have to agree with you on all those points. Leaving aside the time issue, the facilities for the journey are appalling, but they will considerably improve when the 22ks fully take over from those glorified darts (whenever that will be!) Don't think the Rosslare line will ever get a dining carriage though-just the trolley.
Looks like the 13:05 will be forwarded to 13:30/35 for the new timetable btw
