Belfast - Dublin train

Wondering how busy it is for the 16.05 and 18.05 departure on a weekday (Tuesday) - I see you can't book seats online just the ticket.

Fridays can be busy with groups going to party, and if there's an event on in Dublin that night it can get busy. But 9 times out of 10 you'll have your pick of seats on both services midweek.
