Today the route begins at Hospital Infanta Sofía (San Sebastián de los Reyes) and ends at Puerta del Sur (Alcorcón).

The line links the towns of Alcobendas and San Sebastián de los Reyes with Madrid.

The section between Alonso Martinez and Nuevos Ministerios was completely built, with an intermediate station at Gregorio Marañón.

Proposed plans for Line 10 include the building of a new station between Colonia Jardín and Aviación Española called Dario Gazapo.

Also there are plans to extend the line from Puerta del Sur to Mostoles Central and further onto the new Xanadu Shopping Centre.
