Expansion and improvement works in the station to optimise the railway and commercial exploitation, and reorganise the interior space according to new requirements. 

Sants station is Spain´s second most important railway station after Atocha (Madrid) in terms of passenger numbers. It moves around 30 million passengers per year, of which 18m are users of lines R1, R2, R3 and R4 of the Barcelona overground commuter train network.

After years of waiting the high speed connection between Madrid and Barcelona entered into service and the works for extension of the station began. The complex required a radical overhaul and modernisation consistent with the arrival of the AVE.

 Ineco has wide experience and recognised prestige in projects of this type and was entrusted with management of the works. The structure of the station underwent various modifications to upgrade the interior according to the new needs.

Reorganisation of infrastructures

Ineco constructed 38,100 m² devoted to railway-related activities both for the high speed and the conventional networks, divided into an area with 7 platforms with a total length of 3.2 kilometres and various technical buildings.

The works have also enhanced the mobility and fluidity of users in the interior of the station. The main vestibule has been reorganised to house new offices, shops or leisure zones and a new underground car park with capacity for 1,015 vehicles has been built.


The planning and articulation of the project was a stern challenge for Ineco's engineers. The construction data forwarded by the station failed to provide details of the infrastructures and this obliged the company to perform data collection and analysis directly on the spot to apply specific solutions to construction problems as they arose.

Moreover, the works were carried out while the station remained open to users at the normal operating levels (400 trains and 100,000 passengers daily). Ineco was able to manage this situation and the works progressed amidst the flow of passengers and machinery operating in the station.
