São Paulo Metro in the context of Estação da Luz

Bom Retiro is a central district in the city of São Paulo, Brazil. It is primarily commercial but has industrial and residential areas.

The district is served by Line 1 (Blue) of the São Paulo Metro and by the lines 7 (Ruby), 10 (Turquoise), and 11 (Coral) of the CPTM. There is also a planned station for Line 4 (Yellow) of the São Paulo Metro.

Line 15 (Silver) (Portuguese: Linha 15–Prata) 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 is South America's first mass-transit monorail and is the first system in the world to use the Bombardier Innovia Monorail 300. When completed it will be the largest and highest capacity monorail system in the Americas and second worldwide only to the Chongqing Monorail. The first section, from Vila Prudente to Oratório, opened on 30 August 2014, initially running 10 AM–3 PM on weekends only. As of 26 October 2016, the line is operational from 4:40 AM–12 AM. The line has a free connection to Line 2-Green on Vila Prudente station and future connection to CPTM Line 10-Turquoise on Ipiranga station.

Built using completely driverless technology, the line is currently 14.6 km (9.1 mi) long and has eleven stations in the stretch between Vila Prudente and Jardim Colonial. When complete, it will be approximately 27 kilometres (17 mi) long and have eighteen stations, beginning at Ipiranga and ending at the future Hospital Cidade Tiradentes. The proposed completion of the full line is projected to be beyond 2022.

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 Companhia Paulista de Trens Metropolitanos (CPTM) (lit. 'São Paulo Metropolitan Trains Company') is one of the rapid transit companies serving the city of São Paulo, alongside the São Paulo Metro, ViaQuatro and ViaMobilidade, all four forming the largest metropolitan rail transport network of Latin America. It was created on 28 May 1992, from several railroads that already existed in Greater São Paulo, Brazil.

Part of the Greater São Paulo rail system, the CPTM currently operates 57 stations in five lines, with a total length of 199 kilometres (124 mi). The system carries about 2 million passengers a day. On 7 December 2018, CPTM set a weekday ridership record with 3,221,035 trips.

Line 4 (Yellow) (Portuguese: Linha 4–Amarela) is one of the six lines that make up the São Paulo Metro and one of the thirteen lines that make up the São Paulo Metropolitan Rail Transportation Network. Originally called Southeast-Southwest Line, the line goes from Vila Sônia to Luz and currently has 11 stations along its 12.8 km (8.0 mi) and transports around 800,000 users/day. It is the most modern subway line in Latin America and the first line in the region to utilize driverless trains and platform screen doors in all stations.

The construction of the line was divided into two phases: The phase one was completed in 2011 and the phase two was partially inaugurated between 2014 and 2018 and was fully completed by 2021.
