In cooperation with the local emergency services and the Spanish Army, around 40,000m3 of water was extracted from a 1.8km section of the tunnel, located 40m below the surface.

Adif also replaced 4km of cable used for communications and signalling, as well as 4km of electric wiring, two water extraction pumps, eight point motors, and service and emergency lighting along the whole flooded section.

Adif says it will work with the Catalan water management agency to convert the G├╝ell river into a canal to prevent future flooding in the tunnel. Water from the river entered the Girona tunnel on September 29 through a nearby shaft left open after tunnel boring was completed in 2011.

The seven international services operated by Spanish passenger operator Renfe and French National Railways (SNCF) which connect Barcelona with Paris, Lyon, and Toulouse, and Madrid with Marseille, are now operating normally.
