The Costa del Sol could face one of its biggest rail disruptions in years after Adif’s planning documents pointed to a long closure on the C-1 Cercanías line from late 2027.
The planned cut is linked to major works on the Málaga–Fuengirola commuter line, including the duplication of track between Campamento Benítez and Plaza Mayor, improvements around the airport tunnel, and works under the Guadalmedina. Reports based on Adif’s capacity restriction documents say the interruption could last around five and a half to six months, between the final quarter of 2027 and early 2028.
Not just a technical rail project
On paper, this is an infrastructure scheme designed to modernise one of southern Spain’s busiest commuter routes.
In practice, it could affect thousands of daily journeys between Málaga city, the airport, Torremolinos, Benalmádena and Fuengirola. The C-1 line is not only used by local residents. It is also a key route for tourists, airport passengers, students, workers and people trying to avoid the already congested coastal roads.
Málaga Hoy reports that the “total cut” would affect the line between Málaga and Torremolinos, which is necessary to carry out the track duplication works. That distinction matters. It does not simply mean every kilometre to Fuengirola is being dug up at once, but a closure on the Málaga–Torremolinos section would still break the corridor used by the whole C-1 service.
Why Marbella and Estepona would feel it too
The disruption would also be felt beyond Fuengirola.
For years, residents and visitors travelling towards Marbella, Estepona and the western Costa del Sol have relied on the C-1 as the first rail stage of a journey that already has to continue by road because there is no train line beyond Fuengirola. If the planned works cut rail access between Málaga and Torremolinos, even that partial train option would disappear.
That could place more pressure on buses, taxis, private transfers, hire cars and the A-7/AP-7 corridor. For tourists arriving at Málaga Airport, the impact would be especially obvious: the current option of taking the train westwards before switching to road transport would no longer be available during the closure.
Mayors demand answers
The scale of the possible disruption has already triggered a political response.
Mayors from Málaga, Torremolinos, Benalmádena and Fuengirola have demanded urgent explanations from the Ministry of Transport, saying they were surprised to learn of the plans through media reports rather than through prior institutional communication. In a joint letter, they called for transparency, a detailed works plan, an impact study and effective replacement transport.
Their position is not that the line should never be improved. Local leaders have acknowledged the need to modernise the rail corridor. Their concern is whether a prolonged interruption can be managed without creating chaos for commuters, businesses and visitors.
Government promises alternative transport
The central government has said it will guarantee alternative transport while the works are carried out.
Cadena SER reports that the government intends to provide a replacement system during the closure, while defending the need for the works to improve the C-1 line. The Subdelegation of the Government in Málaga has argued that the project is necessary for modernising the infrastructure and improving sustainable mobility on the Costa del Sol.
But the details will matter. A replacement bus or shuttle system would need to cope with airport passengers, luggage, peak commuter traffic and tourists unfamiliar with local routes. It would also have to connect effectively with existing bus services to Mijas, Marbella, Estepona and other towns further west.
The missing coastal train question returns
The planned closure has revived a familiar frustration: the Costa del Sol still lacks a rail connection beyond Fuengirola.
The Ministry of Transport awarded a feasibility study in 2025 for a wider coastal rail corridor between Nerja and Algeciras, including the missing stretches from Fuengirola to Marbella, Marbella to Estepona, and Estepona to Algeciras. But that is still at the study stage, not a working transport solution.
That is why the C-1 matters so much. It is the only rail spine currently serving the western Costa del Sol as far as Fuengirola. If that access is interrupted, even temporarily, the absence of a train to Marbella and Estepona becomes harder to ignore.
Mobility is already a major concern
The timing also lands in a province where mobility has become a major public issue.
Cadena SER reported this week that mobility has risen sharply as a concern among residents in Málaga province, becoming the second-biggest issue after housing in the 2026 provincial barometer. The same report said expansion of the Cercanías towards Algeciras was among the most frequently cited solutions.
That gives the planned closure a wider significance. It is not only a future works notice. It touches a daily problem that residents already feel: how to move around one of Spain’s busiest and fastest-growing coastal regions without relying almost entirely on roads.
What happens next
For now, the dates remain planning forecasts rather than a day-by-day public timetable. The works are expected from late 2027 into early 2028, and the project details could still shift before contracts, schedules and replacement transport are finalised.
But the warning is already clear enough. If the C-1 line is cut between Málaga and Torremolinos for several months, the impact will not stop at Torremolinos or Fuengirola. It will ripple across the wider Costa del Sol, from airport transfers to daily commuting and journeys towards Marbella and Estepona.
For a coast still waiting for a complete rail connection, even a temporary closure of the existing line could feel like a much bigger transport test.
