[Traincustomer]

The 2005 Dublin to Carlow seems to enjoy quite a good level of patronage, it would be a shame to see it discontinued. While users will have a coach alternative at similar times [viz. J.J. Kavanagh's Dublin-Tramore route (for Carlow) and their Dublin-Clonmel route for Athy.] this is not realistic on a daily basis due to the additional cost.

I understand there was a later train Dublin-Carlow a few years ago (circa 2200)?

Ideally it would be good if the almost four hour afternoon gap in services on the Waterford line could be filled. No Waterford-bound train between 1130 and 1505.
In the reverse direction nothing from e.g. Carlow between 1621 and 2002 - so the train doesn't suit most workers.

With the 22000s on the route it should now be possible to reduce Kilkenny dwell time to circa 4 minutes on every train. 1045 ex Waterford generally seems to have a prolonged wait in Athy - upwards of 10mins. I feel it could leave Waterford at 1050 and still depart Athy 1222.

1505 ex Dublin (arr. Waterford 1740) needs to connect with the 1734 Waterford-Rosslare, possibly through retiming the latter and using the bay platform at Waterford.
