The comprehensive upgrading of accessibility at the Palacio de Congresos station in Seville, executed by Extraco, included the adaptation of accesses, road surfaces and handrails to current regulations, as well as the ground consolidation and platform improvement.

A new lighting system was also installed and work was done on the signaling and finishing of the shelters.

A new access building was built on the west side.

The works were carried out entirely without interrupting the Renfe commuter rail service. It also represented the most significant undertaking on these facilities since they were put into service twenty years ago.
