Transport in São Paulo in the context of "Line 15 (São Paulo Metro)"

Line 1 (Blue) (Portuguese: Linha 1–Azul) is one of the six lines that make up the São Paulo Metro and one of the thirteen lines that make up the Metropolitan Rail Transportation Network. It was the first line built for the São Paulo Metro and also the first metro line built in Brazil. It links Tucuruvi Station to Jabaquara Station. Construction began in the late 1960s and was completed in the early 1970s.

The São Paulo Metro (Portuguese: Metrô de São Paulo, [meˈtɾo dʒi sɐ̃w ˈpawlu]), commonly called the Metrô, is one of the rapid transit companies serving the city of São Paulo, alongside the São Paulo Metropolitan Trains Company (CPTM), ViaQuatro and ViaMobilidade, all four forming the largest metropolitan rail transport network of Latin America. The metro system carries about 4,200,000 passengers a day.

The six lines in the metro system operate on 104.4 kilometres (64.9 mi) of route, serving 91 stations. It is complemented by a network of metropolitan trains operated by CPTM and ViaMobilidade, which serve the city of São Paulo and the São Paulo Metropolitan Region. The systems combined form a 382 km (237 mi) long network, all accessible via one single ticket. The metropolitan trains differs from Metro because it also serves other municipalities around São Paulo with larger average distance between stations and freight trains operating in some lines.

The section between stations Luz and Guaianases was completely modernized in late '90s, when many stations parallel to Line 3 - Red were closed. Since then, this part of the Line 11 - Coral is also known as the East Express (Portuguese: Expresso Leste). After the modernized section was opened in May 2000 the line was divided into two sections, and passengers were required to switch trains to proceed. Since April 2019 the line is once again unified, but in rush hours additional trains might travel between Luz and Guaianases only in order to increase seat availability to the most demanding stations.
