The only non-peak trains Heuston - Waterford are the 07:30 and the 11:35.
Everything else is almost always full. 15:05, 16:25 & 18:35
You'd actually cause more chaos on either of the 15:05 or especially the 16:25 if you reserved a carriage.
At least the 18:25 has a reserved/first carriage which is where a good chunk of them ended up.
