Line 6-Orange debuts in São Paulo with assisted operation, deep stations, and high-capacity trains, in a project that combines urban mobility, underground engineering, and historical memory on the route between the north and west zones of the São Paulo capital.
The Line 6-Orange of the São Paulo Metro began operating for passengers on July 3, 2026, still in its initial phase, with six stations on the route between João Paulo I, in the north zone, and Perdizes, in the west zone.
During this period of assisted operation, the section operates from Monday to Friday, from 10 am to 3 pm, without charging a fare, in a phase used to monitor the system’s performance before expanding the service.
With symbolic and technical significance for São Paulo’s mobility, the branch combines deep stations, underground crossing in complex areas, and trains designed to accommodate up to 2,044 passengers per train.

When complete, the route will have 15 stations and more than 15 kilometers in length, expanding the connection between neighborhoods in the north zone, west zone, and the central region of the capital.
Line 6-Orange connects north zone to west zone
In this initial stage, passengers can board at the João Paulo I, Freguesia do Ó, Santa Marina, Água Branca, Sesc-Pompeia, and Perdizes stations, distributed along the first section delivered to the public.
Through the Água Branca Station, the new line also offers integration with the CPTM’s Line 7-Ruby, at a point considered strategic for connecting the branch to the existing metropolitan network.
Planned to connect Brasilândia, in the north zone, to São Joaquim Station, in the central region, the Line 6-Orange was designed to shorten daily commutes in an area with high demand for public transportation.
The forecast announced for the complete branch is to reduce a journey that can take about 1 hour and 30 minutes by bus to approximately 23 minutes by metro, when all stations are operational.
Since the project phase, the route has been called the “University Line,” as it passes through areas near institutions like PUC-SP, FAAP, Mackenzie, and Unip.
This association with higher education helped establish the nickname even before the opening of the first section, as part of the route serves regions with a strong circulation of students.
Água Branca Station sets operation record
Among the points that draw the most attention in the construction, the depth of the stations takes a central place, especially because the new branch passes through areas with already established underground structures.
With the inauguration of the first section, the Água Branca Station has been pointed out as the deepest in operation in Latin America, at 47.8 meters below the surface, surpassing the Santa Cruz Station, which is 41.5 meters deep.
This milestone, however, does not end the underground challenges of the Orange Line 6, as other stops on the branch were planned at even deeper levels.
When the line is fully completed, the future Itaberaba-Hospital Vila Penteado Station, in the northern zone, is expected to exceed 65 meters in depth and hold the largest underground milestone of the project.
According to the state government, the depth of Água Branca is related to the geological conditions of the region and the need for the tunnels to pass under the Tietê River and under the Yellow Line 4.
Due to this overlap of structures, the new metro required deeper excavations and a greater safety margin between tunnels, rivers, existing stations, and other urban interferences.
In the capital’s layout, the complexity also appears in the passage through dense regions, with buildings, avenues, underground networks, and public equipment distributed in areas of high circulation.
This set of obstacles helps explain why the engineering of the Orange Line 6 needed to advance into lower layers of São Paulo’s subsoil.
Trains on the Orange Line 6 will have greater capacity
To meet the expected demand on the new branch, the fleet of the Orange Line 6 will consist of 22 trains, each designed to transport 2,044 people per composition.
The compositions will be able to reach up to 90 km/h, although the speed in commercial operation is expected to be 80 km/h, according to the parameters defined for the regular operation of the system.
Inside the carriages, the design prioritizes circulation and the transport of standing passengers, with interconnected cars and seats positioned on the sides.
This arrangement brings the train closer to the model used in high-demand international systems, such as the London Underground, cited for the comparison of the internal layout.
By freeing up more space in the central corridor, the configuration seeks to reduce bottlenecks during boarding and disembarking, especially during peak times when passenger concentration tends to be higher.
With fewer obstacles between the doors, circulation tends to be more direct within the carriages, although the perception of comfort depends on the actual demand during operation.
Assisted operation begins with reduced hours
In the initial phase, the service operates with reduced hours, free access, and a limited number of trains, in a model adopted to accommodate adjustments before expanding the operation.
The start of the operation foresees one train per track and an estimated interval of 13 minutes, while the full phase should increase the offer as the branch’s operation evolves.
During the assisted operation, each station will have only one access open to the public, and the trains will be operated by drivers, despite the line being designed to operate automatically in the future.
Connected to the Concessionária Linha Uni and the Government of São Paulo, the Linha 6-Laranja is part of a public-private partnership model that involves both the construction and operation of the branch.
In this format, the contract consolidates the responsibility for the implementation of the work and the operation of the service within the same structure, unlike projects where construction and operation are separate.
Archaeological finds mark the future 14 Bis-Saracura
In addition to engineering challenges, the works gained historical relevance with the archaeological finds in the region of the future 14 Bis-Saracura Station, in Bela Vista, central São Paulo.
The discovery reinforced the relationship between urban intervention and the memory of the black population in the city, by associating the mobility project with traces linked to the Saracura territory.
With the name change to 14 Bis-Saracura, the future station began to carry this historical dimension within the metro project itself.
The reference to Saracura refers to the territory associated with the former quilombo and black occupations in the region, transforming the station into a point of attention that goes beyond passenger circulation.
By combining mobility, underground engineering, and urban memory, the Linha 6-Laranja stands out not only for the size of the work or the depth of its stations.
In the subsoil of São Paulo, the new branch reorganizes movements, reveals buried historical layers, and leaves a question for the city: to what extent does the capital still need to dig deeper to move forward?
