In 2026, the main bus services from Belfast to Dublin (operated by Translink Goldline, Aircoach, and Dublin Express) typically depart from the Belfast Grand Central Station (which replaced the old Europa Buscentre). The primary stops on the way to Dublin include Dublin Airport (Terminals 1 and 2), which is the most popular drop-off point, and finally Dublin City Centre (O'Connell Street or Custom House Quay). Some "express" services run non-stop from Belfast to the Airport in about 1 hour and 50 minutes. If you are taking the X1 or X2 Goldline service, there may be intermediate stops in Banbridge and Newry. It is important to note that since 2024, the "Dublin Express" service has significantly increased frequency, often running every 30 minutes. All these buses are equipped with Wi-Fi and USB charging points in 2026. Because these routes cross the international border between the UK and the Republic of Ireland, travelers should always have a form of ID ready, although formal "hard" border checks remain rare under the Common Travel Area (CTA) arrangements.
