The platform roofs, in form of an inverted hull, are partially covered and are made up of steel and glass. They are 27m high and 157m long spread between the brick flanking buildings.
The station was expanded in 1985 to incorporate additional tracks. The original building was converted into a commercial complex with a tropical garden, cafés and night clubs in 1992. The main tracks from the old terminal were shifted to the new terminal, which is adjacent to the AVE high speed rail, while the underground platforms serve commuter trains. This expansion was designed by Spanish architect José Rafael Moneo Vallés.
