The Community of Madrid gave final approval on Monday to a long-delayed expansion of the metropolitan rail network, committing 4.2 billion euros to the construction of three new lines and 28 additional stations across the southern and eastern suburbs. The project, which has been in various stages of planning since 2017, is expected to be completed in phases between 2028 and 2031.
The expansion addresses a longstanding gap in the network's coverage. The southern districts of Vallecas, Villaverde, and Usera — among the most densely populated areas of the city — have long had limited metro access, forcing residents to rely on a bus network that struggles to cope with demand during peak hours.
What's Being Built
The approved plan includes a new circular line connecting the southern suburbs directly to the main interchange stations, a branch extension from the existing Line 11 into the Coslada and San Fernando corridor, and a new light rail connection to the Getafe industrial zone. The project will also involve the modernisation of 14 existing stations, several of which have not been substantially upgraded since the 1990s.
The regional government has committed to funding the project through a combination of European structural funds, regional bonds, and a modest increase in metro fares — a provision that has already attracted criticism from opposition parties and passenger associations.
Political Background
The approval came after months of negotiations between the regional government and the central administration over the allocation of EU cohesion funds. The final agreement includes a commitment from Madrid to maintain fare subsidies for low-income residents throughout the construction period.
Construction is expected to begin in the first quarter of 2026, subject to the completion of environmental impact assessments currently underway.
