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.^[1] In 1980, the stations Estácio and Uruguaiana were added.^[1] The following year (in 1981), the Botafogo, Flamengo, and Largo do Machado stations opened. In 1982, the line was extended to Saens Peña with the São Francisco Xavier and Afonso Pena stations added.^[1] In 1998, the Cardeal Arcoverde station opened in Copacabana. The Siqueira Campos station opened in 2002, while the Cantagalo Station opened in 2007.

Inaccessibility for disabled persons on Line 1 has come under scrutiny in recent years. When the line opened in 1979, there was no appropriate legislation to mandate accessibility and therefore not built to current access standards.^[2]
