Companhia do Metropolitano de São Paulo
State-controlled urban rail company responsible for developing and operating major parts of the São Paulo Metro network.
Last updated August 21, 2026
Overview
Companhia do Metropolitano de São Paulo, commonly known as Metrô SP or Metrô de São Paulo, is a mixed-economy urban rail company based in São Paulo, Brazil. It was created on April 24, 1968, by the Municipality of São Paulo to develop a modern metropolitan transportation system for the rapidly growing São Paulo urban area. Its mandate covers the planning, design, construction and operation of metropolitan rail transport, with particular emphasis on the subway network serving the capital and its surrounding metropolitan region. The company is majority controlled by the Government of the State of São Paulo and operates under the state’s metropolitan transport administration. Although it is a public-sector enterprise, its corporate structure is that of a mixed-economy company rather than a conventional municipal department. This arrangement has allowed Metrô SP to combine public ownership and policy oversight with an operating and engineering organization dedicated to large-scale rail infrastructure. Metrô SP’s activities extend beyond the simple running of passenger trains. The company has historically been involved in route development, system planning, civil works, stations, railway systems, rolling stock coordination and the continuing expansion and modernization of the São Paulo Metro. Its network forms one of the principal components of the metropolitan public transport system, connecting with other rail and bus services and carrying passengers across some of Brazil’s most densely populated urban districts. The company currently owns and operates four São Paulo Metro lines, while other lines in the broader metro system are operated under separate arrangements. Its principal operational portfolio includes the Blue Line, Green Line, Red Line and Silver Line. The network’s role is especially important because São Paulo is a large, highly urbanized metropolitan region in which rail transport provides high-capacity movement along corridors that are difficult to serve efficiently with roads alone. Metrô SP is also part of Brazil’s organized passenger-rail sector through its membership in the National Association of Passenger Carriers on Rails, known as ANPTrilhos. Alongside Companhia Paulista de Trens Metropolitanos (CPTM), it has been part of wider discussions about the future organization, concessions and possible privatization of metropolitan rail transport in São Paulo. The state administration discussed a plan to place the wider rail network, including Metrô SP and CPTM, under a more privatized model by 2024. The available reference material does not establish that the entire company was privatized, so its current status is retained as active and state-controlled.
History
Companhia do Metropolitano de São Paulo was established by the Municipality of São Paulo on April 24, 1968. Its creation reflected the need for a dedicated institution capable of planning and delivering high-capacity metropolitan transport in a city whose population and urban footprint were expanding rapidly. Rather than limiting the organization to train operations, the founding mandate included the development, design, construction and operation of a metropolitan transport system, giving the company a broad role in both infrastructure delivery and service management. Over time, Metrô SP became a central institution in the development of São Paulo’s subway system. The company’s work has encompassed the technical and organizational requirements of a large urban railway, including network planning, station development, construction, railway systems and passenger operations. Its metro infrastructure became one of the main fixed-route transport elements in Greater São Paulo, complementing suburban rail and bus services. The company is structured as a mixed-economy enterprise, with the Government of the State of São Paulo holding the majority of its assets. Administrative oversight is exercised through the state Secretariat of Metropolitan Transports. This governance model places Metrô SP within the public metropolitan transport system while preserving a corporate structure focused on engineering, operations and asset management. Metrô SP’s present operating portfolio covers four lines of the São Paulo Metro. These are commonly identified as the Blue Line, Green Line, Red Line and Silver Line. The wider São Paulo Metro network includes lines operated through arrangements separate from CMSP, meaning that ownership and operation of the entire metro system should not automatically be attributed to Metrô SP. The company nevertheless remains one of the system’s defining operators and infrastructure institutions. In addition to its direct transport role, Metrô SP participates in the national passenger-rail sector through ANPTrilhos. Its future has been connected to broader state policy debates concerning concessions and privatization. The state administration expressed an intention to privatize the metropolitan rail network, including Metrô SP and CPTM, by 2024. The supplied reference does not provide evidence that this intention was fully implemented, and no unsupported ownership change is recorded here.
