Checking Belfast–Dublin Train Status

I don't have real-time data. For current Belfast–Dublin train status, check:

• Translink (NI Railways) website/app
• Irish Rail (Iarnród Éireann) website/app
• National Rail Enquiries (UK)
• Twitter feeds of both operators

Services run roughly hourly; journey ~2h 15m. Disruptions occur for maintenance, weather, or security alerts.
