Line 1 (Orange) of the Rio de Janeiro Metro serves the city's downtown business centre, the tourist areas in the city's South Zone, and several neighbourhoods in the North Zone.

It is the original line of the Rio de Janeiro Metro system and it was constructed from June 1970 to March 1979 (with a hiatus between 1971 and 1974 due to lack of funds).

In 1979, the line began operations with 5 stations: Praça Onze, Central, Presidente Vargas, Cinelandia, and Gloria.

In 1982, the line was extended to Saens Peña with the São Francisco Xavier and Afonso Pena stations added.
