The Red Line has two tracks: Track 5 southbound and Track 6 northbound. The Red Line has both island and side platforms; however, unlike the Spanish solution, all platforms are used for both boarding and alighting. Staircases connect each platform to both Green Line island platform and the fare lobby; exit-only escalators lead from the southern end of the side platforms to the surface. A backup control room for the subway system is located on the Green Line level over the middle of the Red Line platforms.
