The Dublin-Belfast Line or The Great Northern Main Line (Dublin line by NI Railways and Belfast line by Irish Rail) is a 112-mile (181 km) semi-electrified railway connecting Belfast Grand Central in Northern Ireland to Dublin Connolly in the Republic of Ireland. The key towns and cities of Skerries, Drogheda, Dundalk, Newry, Portadown, Lurgan, and Lisburn are situated along the line. The Dublin-Belfast Line is the busiest railway route on the island of Ireland, carrying a mixture of intercity rail, regional rail, commuter rail traffic and freight traffic. It is uniquely significant as the only railway line that crosses the Republic of Ireland–United Kingdom border.
