This is the first Spanish metro line to use the new administrative concession model. CAF supplied the rolling stock consisting of 17 light metro units each with 5 cars. These are bidirectional units made up of five articulated carbodies resting on three trucks, a feature being the access at a height of 300 mm above the rail.
They have been designed for complete architectonic integration of the urban transport with the environment of the city of Seville.
