Yeah I saw that map too, but the news section says (which you linked): " This new section of track, which will be opened on Monday (1 August), is 16km long and serves five stations: Nossa Senhora da Paz, Jardim de Alah, Antero de Quental, São Conrado/Rocinha e Jardim Oceânico. " and " Temer attended the maiden voyage of the line between the stations Nossa Senhora da Paz e Jardim Oceânico"
So everywhere there is only Nosa Senhore de Paz and not General Osorio which is interesting.
