Commuters on the vital R2 Sud train line face significant disruption for the next three to four months, as major maintenance works begin on the Garraf rail tunnel on March 16th. The project, announced by the Generalitat de Catalunya, will necessitate a reduced train service and the implementation of an extensive alternative transport plan involving bus replacements and route diversions.

The works, managed by infrastructure administrator Adif, are essential for the upkeep of the tunnel and adjacent viaducts, which are part of one of Catalonia’s busiest rail corridors connecting the Garraf, Baix Penedès, and Camp de Tarragona regions with the Barcelona Metropolitan Area. According to reports from VilaWeb, the ongoing maintenance aims to preserve the infrastructure against the long-term impact of the sea.

Speaking at a press conference, the Minister for Territory, Sílvia Paneque, confirmed the timeline and scope. “These are works that will not be definitive, but they imply an improvement in the internal scope of the tunnel,” she stated, adding that the project is expected to last “between three and four months.” As Barna.News previously reported, the Garraf rail tunnels were set for major renovation in March, and these plans are now being put into action.

Frequency Adjustments on the R2 Sud Line

The core of the disruption stems from the need to operate trains on a single track through the affected section between Sitges and Garraf stations. This will inevitably lead to a reduction in the number of services, with the impact varying depending on the destination.

The Department of Territory has outlined the following service plan for the duration of the works:

  • Barcelona – El Prat de Llobregat: Service will largely continue, with eight trains per hour in each direction.
  • Barcelona – Castelldefels: Frequencies will be reduced, offering six trains per hour.
  • Barcelona – Garraf: Service will be further reduced, providing four trains per hour.
  • Barcelona – Sant Vicenç de Calders: This route will see the most significant reduction, down to two trains per hour. To compensate for the lower frequency, Renfe will operate these services with double-composition trains to maximise passenger capacity.

In addition, Renfe will station reserve trains at Sant Vicenç de Calders and Vilanova i la Geltrú to respond to any unforeseen peaks in demand.

Bus Replacements for Regional Services

Passengers using the Regional services south of Barcelona towards destinations such as Tarragona, Reus, and Tortosa will face a modified journey. While the train will operate as normal between Barcelona and El Prat de Llobregat, direct bus services will cover the section from El Prat to Sant Vicenç de Calders. The regular train service will then resume from Sant Vicenç de Calders southwards.

As a further measure on weekdays, Renfe will reroute two morning peak-hour trains into Barcelona and two evening peak-hour trains leaving the city via Vilafranca del Penedès. While this diversion will add approximately 40 minutes to the journey time, it provides a direct rail connection without the need for a bus transfer.

A ‘Well-Sized’ Alternative Plan

The Generalitat, Adif, and Renfe jointly developed the alternative transport plan, incorporating feedback from local councils and community platforms. Minister Paneque expressed confidence in the arrangements, describing the plan as “well-sized” and confirmed it would remain in place for the duration of the works to “guarantee mobility.” She also left the door open to adjustments, stating that changes could be made “if improvements are detected,” as they did during recent works on the R3 line.

A cornerstone of this plan is a significant boost to interurban bus services, a strategy becoming more common as Renfe prepares for service cuts elsewhere. Authorities will provide a total of 14,400 additional daily bus seats, focusing on peak hours. Key reinforcements include:

  • e16 (Barcelona – Sitges): An extra 2,280 seats.
  • e15.1 (Barcelona – Vilanova): An extra 2,400 seats.

Furthermore, in response to requests from affected towns, they will also launch a new direct bus service between Altafulla, Torredembarra, and Barcelona, with two services in each direction during morning and evening rush hours. The necessity of these works highlights the ongoing challenges of maintaining coastal infrastructure, a topic of wider debate as a minister recently urged a discussion on moving the R1 line inland.

Commuters should strongly check the Rodalies de Catalunya website for updated schedules and plan their journeys in advance throughout the maintenance period.
