The Giant's Causeway and Bushmills Railway (GC&BR) is a 3 ft (914 mm) narrow gauge heritage railway operating between the Giant's Causeway and Bushmills on the coast of County Antrim, Northern Ireland. The line is two miles (3.2 km) long.
The Giant's Causeway Tramway, operated by the Giant's Causeway, Portrush and Bush Valley Railway & Tramway Company Ltd, was a pioneering 3 ft (914 mm) narrow gauge electric railway operating between Portrush and the Giant's Causeway. 9 1⁄4 miles (14.9 km) long, it was hailed at its opening as “the first long electric tramway in the world”. Promoted by W.A. Traill it was powered by hydroelectricity from an elevated third rail, although steam tram engines were also used in its earlier years, and the power supply was converted to overhead wire in 1899. It opened to Bushmills in 1883, the extension from there to the Causeway following on 1 July 1887. The line did not reopen after the end of the 1949 season on 20 September, and was subsequently dismantled.
