Yes, you can easily travel from Dublin to Belfast using the Enterprise train service, which is a joint operation between Iarnród Éireann (Irish Rail) and Northern Ireland Railways. In 2026, the service has been significantly upgraded, now offering hourly departures throughout the day. The journey begins at Dublin Connolly Station and terminates at the newly opened Belfast Grand Central Station (replacing the old Lanyon Place and Great Victoria Street hubs). The trip takes approximately 2 hours and 10 minutes. Onboard, you have a choice between "Enterprise Class" (standard) and "Enterprise Plus" (first class), the latter of which includes larger seats, complimentary refreshments, and an onboard host. Tickets can be booked online through the Irish Rail or Translink websites. This route is a popular choice for both commuters and tourists because it avoids the traffic of the M1 motorway and offers scenic views of the Irish countryside and the Malahide estuary.
