History
This line, initially called the ''East-West line'', was only planned to be long, connecting the
Casa Verde and
Vila Maria districts of São Paulo, passing through the center of
Barra Funda,
Sé, and
Tatuapé, and be completely underground. But after a lengthy debate, it was decided that it would be constructed on the surface, taking advantage of the old
Rede Ferroviária Federal train bed and sharing of its lines—a move that prevented many
expropriations.

Construction began in 1972. With this design change, the East-West line would then be more than long between
Praça da Sé and
Guaianases, parallel to the railroad tracks. The stretch between
Guaianases and
Calmon Viana, in
Poá was planned to be built in a second phase, making full use the rail bed. The strength of this design change would be a cost equivalent to one third of the original budget. Because of international trends that dictate that the rail for metro systems used for urban transport be made exclusive to the metro, the design was changed again.

It was up to the Rede Ferroviária Federal (predecessor of

Anhangabaú and
Santa Cecília stations was closed to allow for the use of a
