Source-derived summary

The Rio de Janeiro Metro (Portuguese: Metrô do Rio de Janeiro, Portuguese pronunciation: [meˌtɾo du ˈʁi.u dʒi ʒɐˈnejɾu]), commonly referred to as just the Metrô (Portuguese pronunciation: [meˈtɾo]) is a rapid transit network that serves the city of Rio de Janeiro, Brazil. The Metrô was inaugurated on 5 March 1979, and consisted of five stations operating on a single line. The system currently covers a total of 58 kilometres (36 mi), and serves 41 stations.

The metro system is nominally divided into three lines but, because Lines 1 and 4 are operationally the same line, it effectively operates as two: Line 1/4 is 32 kilometres (20 mi) long and runs from Uruguai / Tijuca station in Tijuca to Jardim Oceânico / Barra da Tijuca station in Jardim Oceânico; Line 2 is 30.2 kilometres (18.8 mi) long and runs from Pavuna station in Pavuna to Botafogo station in Botafogo. Line 1/4 shares track with Line 2 between Central and Botafogo, a stretch that includes 10 stations and approximately 5 km (3.1 mi) of track. The Rio de Janeiro metro has the second highest metro passenger volume in Brazil after the São Paulo Metro.

Line 1/4 serves Tijuca, the city center, the South Zone and the eastern tip of Barra da Tijuca. It is a semicircular line, and is almost fully underground. Line 2 serves working-class residential neighborhoods in the North Zone, as well as the city centre and part of the South Zone. It is a northwest-to-southeast line, and the non-shared portion is almost completely above-ground (mostly at-grade and partly elevated); the section of the line that interlines with Line 1/4 is entirely underground.
