The second major milestone or main phase of the La Sagrera-Sant Andreu operation, developed by Adif Alta Velocidad, continues to exceed forecasts with less than a month before reaching this major milestone, with 90% completion after more than 300,000 hours of work.

This ambitious project has been in full swing since September to bring into service, on 11 December, the new route of the Barcelona-Granollers-Girona line through the interior of the structure of the future La Sagrera intermodal station and the new Sant Andreu Rodalies station.

The work is part of the largest infrastructure operation being carried out in Catalonia and also one of the most ambitious and complex in recent years in Spain. With this level of progress, the overall La Sagrera-Sant Andreu operation exceeds 65% completion of a project that, this year, will involve an investment of more than 100 million euros.

Transformation of mobility in the north of Barcelona

Specifically, this second milestone, developed within the framework of the Transformem Rodalies program, represents an investment of more than 18 million and is expected to be completed before the end of the year, after three months of work.

Its execution requires great technical and human effort - more than 600 professionals involved and the use of heavy machinery - and detailed planning to operate 24 hours a day.

With its entry into service, the definitive route of the Barcelona-Granollers-Girona conventional gauge line will be opened inside the structure of the future Sagrera station (from the area around the Nus de la Trinitat to the Clot tunnel) and the new Rodalies station at Sant Andreu.

The project will contribute to eliminating the surface route, bringing cohesion to the neighborhoods on both sides of the tracks, and to modernizing the facilities, with a new station that is accessible and integrated into its surroundings. It will provide more space for urban uses and contribute to the development of more sustainable, structuring, intelligent mobility, and the socio-economic dynamization of the north of Barcelona.

Two months of work in figures

This weekend saw the completion of the laying of the covering slab for the underground section, which will cover the Barcelona-Granollers and Barcelona-Mataró conventional gauge lines between the exit of the Sagrera structure and the Clot tunnel in the area of the Bac de Roda bridge.

To this end, and in three phases to reduce the impact on train traffic on the R1 line, 246 beams, each 26 m long and weighing 20 tonnes, have been installed.

With less than a month to go before it comes into service and after more than 300,000 hours of work, the progress of the sections (the new Rodalies station at Sant Andreu and the north and south terminals at La Sagrera) can be summarised as follows:

  • Execution of 20 m of screens 19 m deep; 27 piles 14 m deep; sections of a roof supported by more than 400 beams; and walls more than 200 m long
  • Erection of 16.3 km of track, including 9.4 km of slab track, 40 pieces of switches and crossings, 16 km of flexible catenary, and 9 km of rigid catenary. Only the link between the new tracks at Sant Andreu station and the pre-existing tracks in the northern part of the Nus de la Trinitat remains to be completed
  • Conversion of 1,500 m of the ballasted track to slab track and nine sets of the track to slab track
  • Conversion of 600 m of flexible catenary to rigid catenary. The management systems that control traffic in the Sagrera area have been brought into service

The last phase of physical execution of the works will take place between 3 and 10 December [both inclusive] to carry out the northern junctions of the new route of the Barcelona-Granollers line, the reliability tests, the emergency drill, and the training of train drivers. The aim is to bring the new infrastructure into service on Sunday, 11 December.

The new route of the Barcelona-Granollers-Girona conventional gauge line is 4.3 km long, of which 2.8 km is underground. Coming from the north, the route starts under the Nus de la Trinitat. After a section in the open air, it enters the Sant Andreu tunnel, with a stop at the new Sant Andreu Rodalies station, until it reaches the interior of La Sagrera station, where trains will not yet stop.

At both stations, the line will have four tracks, and the tunnel that connects them will have a total of 3. From La Sagrera station, it will be continued, also in a tunnel, to El Clot.
