Euskotren Tranbia, formerly known as Euskotran (abbreviation for "Eusko Tranbia" which means Basque Tram) is an Urban transit tramway system that operates lines in the cities of Vitoria-Gasteiz and Bilbao, plus one under construction in Leioa and an other one, (also under construction) in the city of Barakaldo, all of them in the Basque Country. It began operations for the first time in Bilbao in 2002 and in Vitoria in 2008. It is one of the four commercial brands under which Basque Railways operates, as a public company managed by the Basque Government. The entire network, as the Euskotren Trena network, uses 1,000 mm (3 ft 3 3⁄8 in) narrow gauge rail tracks.
