Hi Lori,
It's lovely to hear that you will be heading up to Belfast soon!
Irish Rail runs the train service as you may well know. There is on going
planned works at Belfast Grand Central station which runs until July 5th so it could be affecting their timetable schedule information as not many tickets are online at the moment after 3rd July in general. I would suggest that you keep checking with
their website as the time gets closer. 🚉
As an alternative, there are bus services from Dublin to Belfast. These take about the same length of time and can also be booked online.
Translink operates the bus and train service in Northern Ireland and they have a
X1 service that you can travel on directly.🚌
Transport for Ireland has a handy journey planner for operators too. The services generally run via Dublin Airport to Belfast so it does involve a service change. Details can be found using the link to
their website.
Hopefully, this will help with your journey.
The 12th July is a
Public Holiday in Northern Ireland, but this shouldn't affect the trains or buses.
What have you planned for your time in
Dublin and also
Belfast?
