Trains – the Enterprise service
Enterprise is the flagship cross-border service jointly operated by NI Railways and Irish Rail. It runs on specially branded locomotive-hauled carriages in a 2-class configuration.
While generally reliable, I remember the branded trainsets as having a tendency to be subject to relatively frequent service issues. In those scenarios, the branded trainsets are replaced by regular Irish Rail or NI Railways units which may or may not have First Class.
Nevertheless, the Enterprise remains the most comfortable way to travel between Belfast and Dublin. There are no other train services between Northern Ireland and the Republic of Ireland.
Where do I board the Enterprise?
| I am departing from | I board the Enterprise at |
|---|---|
| Belfast | Béal Feirste | Belfast Grand Central station |
| Portadown | Port an Dúnáin | Portadown Train Station |
| Newry | An tIúr | Newry Train Station |
| Dundalk | Dún Dealgan | Dundalk Clark Station | Stáisiún Dhún Dealgan Uí Cleirigh |
| Drogheda | Droichead Átha | Drogheda MacBride Station | Stáisiún Droichead Átha Mac Giolla Bhríde |
| Dublin | Baile Átha Cliath | Dublin Connolly Station | Stáisiún Uí Chonghaile |
