Long-awaited and essential renovation works on the historic Garraf railway tunnels, a critical section of the R2 Sud Rodalies line, are scheduled to begin this March. Spain’s Minister of Transport, Óscar Puente, confirmed the start date, heralding a period of significant disruption for commuters for an estimated three months as the vital coastal route undergoes urgent repairs.

Adif, the state-owned infrastructure company, will manage this project to address severe deterioration within the tunnels. Carved into the Garraf Massif coastline and inaugurated in 1881, the infrastructure has suffered for years. Relentless humidity and the saline Mediterranean environment have caused significant corrosion.
According to reports in La Vanguardia, the works have a budget of €3.74 million. They will focus on a tunnel, two viaducts, and an underpass between Sitges and Garraf.
Speaking at an event in Madrid, Minister Puente explained that the project, although already tendered and contracted, was postponed. The Generalitat de Catalunya had previously prioritised other emergency works across the Rodalies network.
Service Reductions and Diversions Expected
The renovations will require operating trains on a single track between Garraf and Vilanova i la Geltrú, which will significantly reduce the line’s capacity. Train operator Renfe has outlined a mitigation plan to manage the disruption, expected to last three months.
Under the new schedule, service frequency will be tiered:
- Barcelona to El Prat de Llobregat: 8 trains per hour in each direction.
- To Castelldefels: 6 trains per hour.
- To Garraf: 4 trains per hour.
- To Sant Vicenç de Calders (Baix Penedès): 2 trains per hour.
These changes will particularly affect the regional lines R13, R14, R15, R16, and R17. These services will be diverted inland via Vilafranca del Penedès to reach Barcelona; this rerouting will add approximately 40 minutes to the journey time. To compensate, Renfe plans to introduce direct bus services, reinforce existing interurban bus routes, and launch a new service connecting Altafulla and Torredembarra with Barcelona.
Underlying Safety Concerns Remain
While the maintenance work addresses immediate structural issues, it does not tackle a deeper, long-standing concern: the lack of modern safety features. As previously covered in Barna.News reports on the R2 South Line, user platforms and unions have for years warned about the absence of emergency exits along the 143-year-old route.
In an interview with Ara newspaper last summer, Francisco Cárdenas, a representative for the UGT union at Renfe, vividly described the perilous situation. “If a major evacuation were needed… emergency teams would have to descend from the road above, or passengers would have to climb up the mountain like goats,” he stated. Adif has confirmed that in the event of an incident, the only option for passengers is to evacuate by walking along the tracks.
A more comprehensive solution, including a new, modern tunnel further inland, was proposed. However, the current project only focuses on maintenance to ensure the line’s continued operation. Similar infrastructure investments are underway across Catalonia, such as Adif’s rail upgrade design contracts in Figueres.
A Network ‘At the Limit’
Minister Puente acknowledged the immense pressure on Catalonia’s public transport network, stating that the sheer volume of complex works has pushed the system “to the limit” of its ability to function without further degrading service. He also highlighted the growing threat to the R1 line, which runs parallel to the coast north of Barcelona, where he said the sea is “imposing itself” on the tracks.
He warned that moving the R1 line would be a monumental challenge due to the high density of housing and the “extremely high” cost of burying the line underground. The minister’s comments paint a picture of a region grappling with ageing infrastructure and the urgent need for investment to ensure the future reliability and safety of its vital transport links.
