São Paulo's Transit Officials Are Fighting Over How to Fix the Worst Commute in the Americas

São Paulo's transit system carried 11.3 million passenger trips on a single Tuesday in May-a figure that broke the previous record set in 2019-and the agencies responsible for running it still cannot agree on who should pay to fix it. That disagreement exploded into public view last week when officials from São Paulo Metro and CPTM, the suburban rail operator, traded accusations at a state assembly hearing in Consolheiro Furtado over budget shortfalls that have delayed the expansion of Line 6-Orange for the third consecutive year.

The timing matters. Mayor Ricardo Nunes is less than eighteen months into his second term and has staked significant political capital on a promise to reduce average commute times in the city from 2 hours 48 minutes-the 2025 Municipal Mobility Secretariat figure-to under 2 hours by 2028. That target looks increasingly implausible. The federal government under President Lula has signalled it will not release the R$4.2 billion in infrastructure transfers the state requested in March unless a unified governance plan is submitted, and no such plan exists.

What São Paulo Is Doing-and What It Isn't

The current approach leans heavily on demand management rather than capacity expansion. The Bilhete Único Metropolitano fare integration program, which allows transfers between Metro, CPTM, and SPTrans buses within two hours for a flat R$5.50, has nudged some riders onto off-peak services. The Secretaria de Transportes Metropolitanos also expanded the Bom Retiro express bus corridor along Avenida Tiradentes in April, cutting travel times between the north zone and the city centre by roughly 14 minutes. But those are patches, not surgery.

Compare that with Mexico City, which opened three new Metrobús lines between 2022 and 2025 and restructured its metro concession contracts to allow private capital to fund rolling stock purchases-something São Paulo's state government has resisted, citing concerns about fare-setting autonomy. Tokyo's approach is even further from the São Paulo model: the Tokyu and Tokyo Metro networks coordinate timetables at the minute level through a joint operations centre established in 1964, ensuring that peak-hour trains on the Denentoshi Line are spaced exactly 2.5 minutes apart. São Paulo Metro's average peak headway on the heavily used Line 2-Green, which runs from Vila Madalena to Vila Prudente, is currently 4.1 minutes-a gap that sounds small until you are standing in a crush on a platform at Consolação at 8:15 on a Monday morning.

The Infrastructure Gap and What Comes Next

The numbers tell a damaging story. São Paulo has 101.1 kilometres of metro track for a metropolitan population of roughly 22 million people. London, with a comparable urban population, runs 402 kilometres. Even Bogotá, a city a fraction of São Paulo's size and economic weight, broke ground on a fully automated metro line in 2020 and is on schedule to open its first 24-kilometre stretch in 2028. São Paulo's last new metro line, Line 4-Yellow, opened its final station, Vila Sônia, in 2018.

The immediate flashpoint is the Expresso Tiradentes corridor extension, which was supposed to reach Cidade Tiradentes in the far east zone by the end of 2026. Construction is now at 34 percent completion according to the Desenvolvimento SP project tracker published in June. If federal funds are unlocked after the unified plan is submitted-officials in Brasília set an informal September deadline-the project could potentially finish by late 2027. If not, it joins Line 6-Orange in a queue of half-built promises.

For the roughly 4 million daily Metro users, none of that is abstract. The practical reality this winter is that trains on Line 3-Red, which passes through Brás, Tatuapé, and Artur Alvim, are running at 184 percent of rated passenger capacity during the morning peak. Transport analysts at Faculdade de Arquitetura e Urbanismo da USP have recommended that the city immediately implement congestion-based pricing on the Paulista and Faria Lima axes to shift car trips to transit-a proposal that has been sitting on the mayor's desk, unanswered, since February.
