Urbos is a family of trams, streetcars, and light rail vehicles built by CAF.
The Basque manufacturer CAF did already have a long history with the construction of trains, including regional and underground metro variants. It started building a tram type in 1993 with a contract for Seville Metro with the delivery of 16 trams between 1993 to 1999. This original tram type was a variant of a Siemens tram type and some components were delivered by Siemens, including bogies and traction motors. After acquiring a contract for Lisbon Trams in 1995, it was decided to start construction of its own model.
There are three generations of Urbos, known as Urbos 1, Urbos 2, and Urbos 3. The first generation was ordered by the tram operator of the Basque city of Bilbao that received 6 trains between 2004 and 2006. Manufacturing locations have initially been in Saragossa and Linares.
