The Santander railway integration project is entering a significant phase as Adif prepares to launch a EUR 41.5 million tender for the first major works at the city’s central station. This stage will focus on the redirection of Iberian gauge tracks and the development of a temporary station facility, setting the foundation for a wider transformation of the rail complex and its surrounding urban space in Cantabria’s capital.
This early phase plays a crucial role in enabling future infrastructure improvements. By diverting the conventional railway lines and constructing a new administrative building for railway operations, space will be created to support the broader redevelopment programme agreed upon by the Ministry of Transport and Sustainable Mobility, Adif, Renfe, the regional government of Cantabria, and Santander City Council.
A provisional corridor will also be established to maintain active rail service during the ongoing works, ensuring that passengers are not disrupted throughout the process.
The launch of this tender follows commitments made during recent meetings of the project’s oversight committee. The forthcoming works, including the temporary station and office building, are fully funded by the Ministry, underlining their importance as strategic upgrades to the national rail network.
Planning, investment and the urban transformation ahead
In parallel with this first phase, Adif is continuing work on the design of two further components: the modernisation and extension of the main passenger building, and a spatial reorganisation plan for the broader station area. The first of these will be entirely state-funded, while the latter is a joint effort shared between Adif, the regional government, and the local council. Both initiatives are expected to enter the tendering phase in 2026, and together they will shape the final configuration of the station and its surrounding infrastructure.
A revised financial overview of the project has set the overall investment at close to EUR 400 million, a figure that includes both the engineering works and associated technical services. Of that total, an estimated EUR 255 million will go towards infrastructure improvements and urban redevelopment efforts, with the latter to be co-financed under a shared funding arrangement between the national infrastructure operator, the Government of Cantabria, and Santander’s municipal authorities.
At present, the station yard accommodates both Iberian and metre-gauge rail systems, operating in physically separate corridors. As part of the integration, these lines will be restructured to streamline operations and improve passenger experience. This will involve moving metre-gauge tracks used for freight and passenger services, reconfiguring the existing Iberian-gauge layout, and combining all services within a temporary, centralised terminal.
The site’s car park will be rebuilt, and significant land adjacent to Calle Castilla—amounting to over 36,000 square metres – will be freed for new urban development. Additionally, a platform structure of nearly 48,500 square metres will be constructed above the realigned tracks, creating a new layer of usable public space.
In mid-2025, Adif issued a separate EUR 70 million tender for the first physical works associated with this transformation, covering the station’s track reorganisation and the new railway office facility. These works are fully funded and are scheduled to begin in 2026 and are expected to be completed in 2029.
The Santander railway integration project reflects a broader vision to enhance both transport infrastructure and the urban landscape. Its implementation will bring multiple long-term advantages, modernising the station to support long-distance, medium-distance, commuter and metre-gauge services within a single facility.
By reconfiguring the layout of the station complex and associated tracks, the project will make rail operations more efficient while also opening up valuable space for public use. Covering the lines and platforms between the station entrance and the pedestrian bridge connecting Calle Alta and Calle Castilla will further contribute to the city’s urban renewal.
Altogether, the initiative represents a transformative step in Santander’s development—strengthening transport links while integrating the railway more closely into the life of the city.
