Spain’s Council of Ministers has authorised more than EUR 72.4m for new works on the Bobadilla–Algeciras conventional railway line.
The package includes EUR 52.2m for installation of the electrification system on the 106 km Ronda–Algeciras section and EUR 20.2m for infrastructure and track upgrades between Bobadilla and Ronda. The projects will be delivered through Adif.
The Ronda–Algeciras contract covers installation of a 2x25 kV AC 50 Hz overhead electrification system together with associated power and telecommunications works. Adif said the project will increase line capacity, improve operational reliability and prepare the route for future integration into the Mediterranean Corridor.
The Bobadilla–Ronda works include track renewal, drainage upgrades, ballast retaining walls and adaptations to bridges and overpasses required for future electrification. The contract covers works between kilometre points 20 and 26.5 of the line and has a planned execution period of 13 months.
Adif stated that more than EUR 514m has already been mobilised for the overall modernisation of the 176 km Bobadilla–Algeciras route. The programme includes full electrification, track renewal, siding extensions, GSM-R deployment and gauge adaptation works in 21 tunnels to accommodate semi-trailers used by the Algeciras–Zaragoza semitrailers by rail service.
Additional contracts linked to the corridor include the construction and maintenance tender for the Marchenilla traction substation and the award of design works for the Ronda traction substation serving the Bobadilla–Ronda section.
The Bobadilla–Algeciras line forms part of both the Atlantic and Mediterranean Corridors and provides rail access to the Port of Algeciras Bay, Spain’s largest port.
The Ministry of Transport and Sustainable Mobility said investment in Atlantic Corridor railway infrastructure reached EUR 3.123bn in tenders during 2025, with a further EUR 1bn launched in the first five months of 2026. Railway tenders increased by 122% compared with 2024.
Among the largest current Atlantic Corridor projects is the future Burgos–Vitoria high-speed line, where EUR 789.2m of tenders have already been launched this year covering three sections of the route. Other schemes advancing include the Basque Y high-speed network, high-speed rail projects in Extremadura, the Toledo–Talavera–Talayuela line and the Seville–Huelva corridor.
The Spanish government plans to invest EUR 12bn in the Atlantic Corridor over the next five years.
