The sudden closure of the Rubí railway tunnel (Barcelona) due to detected cracks threatens the stability of freight transport in Catalonia. The decision to carry out urgent repairs means that all train services between the ports of Barcelona and Tarragona and the French border will be suspended for seven weeks. For the region’s economy, this results not only in supply disruptions, but also increased costs for companies that rely on rail logistics.
According to El Pais, monitoring of the tunnel’s condition revealed dangerous structural deformations, which forced infrastructure operator Adif to order a full suspension of service from March 14. More than 30 sensors recorded levels above the safety threshold, and continued operation is deemed impossible until the reinforcement work is completed. While there is no immediate risk of collapse, the safety hazards have been judged too great.
Limited alternatives
Catalan authorities warn that alternative routes for freight trains are extremely limited. For trains using Iberian gauge, a detour via the Montcada-Manresa-Lleida line is possible, but this route cannot accommodate long or heavy trains. International standard-gauge trains heading to France are forced to use the new terminal station at La Llagosta, generating additional logistical challenges.
In January, there was already a temporary suspension of traffic in this tunnel, which led regional companies to experience shortages of raw materials and components. Business representatives note that a repeated and longer closure could result in production delays and increased costs. According to El Pais, on regular days the Port of Barcelona sends more than 220,000 containers and almost 300,000 vehicles a year by rail, with the railway accounting for up to 12% of container transport and 45% of vehicle shipments.
Pressure mounts on highways
With the closure of the Rubí tunnel, a significant portion of freight will be forced to switch to road transport. However, the AP7 motorway is already running at maximum capacity: at peak hours, up to 120,000 vehicles travel on it daily, including 25,000 trucks. Freight companies warn that not all cargo can be quickly shifted to road because of weight and size restrictions. Some shipments will remain in port warehouses or at rail terminals, increasing the risk of congestion and financial losses.
The situation is further complicated by rising fuel prices, triggered by international developments, and the lack of a clear support plan for transport companies. Industry representatives expect the government to offer compensation or other measures to avoid passing extra costs onto customers. At the same time, according to russpain.com, shifting part of the freight to roads may lead to longer delivery times and higher logistics costs.
Business and government response
Catalan business associations such as Foment del Treball, Pimec, and Cambra de Comerç have already voiced concerns about the state of the railway infrastructure and its impact on the region’s economy. Port of Barcelona officials stress that reliable and stable networks are essential for further development, and repeated accidents and repairs undermine trust in rail transport.
Catalan authorities are demanding urgent investment and an action plan from the central government and Adif for these types of emergencies. Earlier this year, after the first tunnel closure in Rubí, measures were discussed to modernize and strengthen infrastructure monitoring, but new issues arose only six weeks later. As El Pais notes, tunnel surveillance will continue even after the repairs are completed to prevent similar incidents in the future.
Background and similar cases
In recent years, Catalonia’s railway infrastructure has repeatedly caused transport disruptions. In early 2026, free rides on Rodalies were extended amid new restrictions and repair work in the Garraf tunnels, further disrupting southern routes — more details are available in the article on new challenges for Catalonia’s railway. Such situations highlight the urgent need for systemic investment in the modernization and maintenance of transport corridors to prevent economic losses and logistics disruptions. The reliability of railway routes remains a key issue for the development of Spain’s exports and domestic trade.
