Overview

  • The new Metro Line 3 extension, operational since 6:05 AM on April 21, 2025, connects Villaverde Alto to El Casar, improving access for over one million residents in southern Madrid.
  • This expansion integrates MetroSur (Line 12) and Cercanías C-3, allowing seamless transfers between urban and commuter rail networks.
  • Travel time from El Casar to Puerta del Sol has been reduced to approximately 35–37 minutes, significantly benefiting commuters.
  • The €92–110 million project, funded partly by EU Next Generation funds, included the construction of a 2.62 km tunnel and marks the largest Metro expansion in a decade.
  • Despite its completion, the absence of an official inauguration ceremony has spurred political friction over recognition and funding attribution.
