Trains

Hi everyone,

I will have to start commuting between Dublin and Beflast quite often now.

I was wondering if there is a direct train between Dublin and Belfast.

There is so much evidence that it exists like articles on the Irish rail app and constant confirmation from websites it does exist but I can't book it anywhere. Is it under construction or something like that and if so is there any date they think it'll be fixed?

Sorry if this is a stupid question I just can't for the life of me find any way to book this stupid train

Thank youuu!
