Light rail system "DART" (Dallas Area Rapid Transit): 72 km(?), 2 lines, 34 stops, with one underground station Cityplace, opened 1996

Most stations are either at grade-level or on a viaduct. Mockingbird is in an "open cut", and Convention Center is at grade level but completely covered by a parking structure, therefore having a ceiling as if it were underground. The majority of stations have a central platform. Victory station is served only for games at the American Airlines Stadium.
