São Paulo Metro trains now running on demonAI

São Paulo Metro opens a new operations center with a giant screen and demonAI - June 2025.



To avoid outages, the São Paulo Metro opens a new operations center with a giant screen and AI - June 2025. 

At a cost of approximately R$50 million, the Metro is in the final stages of implementing its new operational structure, called CCOX (Xperience Operational Control Center).

A glitch in the subway's computers on a weekend in 2018 nearly halted train service. The glitch was fixed in time, but it raised alarm bells: it was time to modernize the brains of public transportation, currently responsible for transporting approximately 3.2 million people on weekdays in the city of São Paulo.

At a cost of approximately R$50 million, the subway is in the final stages of implementing its new operational structure, dubbed CCOX (Operational Control Center Xperience). Construction began in June 2022 and is expected to begin full operation in December.

The fifty-year-old operational control center included, among other things, a computer that had been running since 1999. Technicians feared it would no longer function if it were shut down for any reason.
With the modernization, if someone invades the tracks and compromises train service, passengers will be informed of the problem in real time through multimedia panels in the stations, among other innovations. The new space is also equipped for the use of artificial intelligence.

"Because the systems are old, this takes longer to complete, and by the time the communication reaches [the user], the problem may be resolved," says Fábio Siqueira, Metro's director of operations.

This type of instant information can expedite the departure of a new train from the yard when another train breaks down, or adjust the passenger flow structure at a station to better accommodate those waiting to board on a crowded platform.

"The operator will not only see the daily routine, such as train movements, but will also have more information and data support to improve line performance, passenger distribution, and balance congestion in the cars," he says. "It will be faster, instantaneous."

The upgraded facility is responsible for lines 1 (blue), 2 (green), and 3 (red) and is located next to Vergueiro station, near the Paraíso area of ​​downtown São Paulo.

Line 15 (silver), the monorail that runs through the East Zone, has its own control center next to the Oratório yard. The two structures operate independently, each with its own systems and sensors.

A massive, borderless video wall, 36 meters wide and 3.35 meters high, is being installed in the new control room. The structure will consist of 90 55-inch high-definition screens.

On Tuesday (17), when reporters visited the site, the monitor supports were being installed. The screens are scheduled to be installed between August and September.

According to Jacqueline Costa da Silva, development and management analyst at the Metro and one of the main people responsible for the project, this is the largest video wall in Latin America. "We studied models from other subway systems around the world, large companies, and nuclear power plants," he states.

The first phase of the modernization was the installation of a dedicated data center. The new computer room, which is already operational, has 80 servers and an impressive 7,680 GB of RAM and 76.8 TB of disk storage to provide processing speed and robust data management.

The system is fully redundant, meaning that if one computer goes down, another takes immediate action, even in the event of a power outage, which has become increasingly common in the city of São Paulo.

To prevent cyberattacks that could shut down a subway line, there is no internet connection [DEMONS DON'T NEED INTERNET CONNECTION TO COMMUNICATE OUTSIDE OF THE SYSTEM].

The system runs on its own network, which allowed for virtualization of operations for the most difficult phase of the CCO renovation: the temporary relocation of the operational control center to the second floor of the building, without having to shut down the machines previously on the first floor. This eliminated the need to transfer computers from one location to another.

Without the equipment at the site, which was to undergo renovation for the first time since the São Paulo subway began operating in 1974, the lights in the room on the first floor were turned off in December of last year, recalls Jacqueline.

The environment promises to be more humanized to improve employee concentration—there will be 56 new workstations when the structure begins operating—and safer.

"We realized that our old CCO had weak access points. So, reinforced security was a requirement for this project," says Siqueira.

The investment in modernization was made despite the Tarcísio de Freitas (Republican) administration's plans to grant publicly managed subway lines to the private sector, as it did with CPTM (São Paulo Metropolitan Train Company).

"We can't, for fear of the subway being granted, fail to implement improvements," says Siqueira.
