The network of "Metro Valencia" has a system lenght of about 150 kilometres. It is used both by low-floor tram lines as well as by high-floor metrolines. A special feature is the integration of four narrow-gauge, largely single-track railway lines into the metro network. This is why the inner city underground lines were also built with metre-gauge tracks. These outer branches reach out very far of the city (line 1 is 98 kilometres long) and are served every 30 to 60 minutes.
The network is operated by FGV (Ferrocarrils de la Generalitat Valenciana) under the brand name → metrovalencia
