src-33af7b4863e9b170Operator page: 30-year PPP concession signed in 2006, partial commercial service from June 2010, 12.8 km, 'driverless' system that runs trains without a driver, about 570,000 people a day, headway down to 90 seconds and to 75 seconds in special peak situations. Other Motiva releases and Wikipedia quote higher daily figures; the entry uses this page's figure.
src-af5c849dd526d5caPeer-reviewed article by Janice Caiafa (UFRJ) on Line 4's automation: the line was designed for unattended operation (UTO) rather than DTO with an attendant aboard. The same author's 2021 ethnography documents that the concessionaire nevertheless keeps an agent on the trains.
src-d67e8e48bc650fdfFrom the weekend of 15–16 March 2025 the monorail runs GoA4/UTO, at first on weekends only, later extended to off-peak and then all service; the Metro says no operator will lose their job; the Metroviários union and the national federation dispute its safety.
src-f4938d9d7b3ea8d7Court's own newsroom: the 14a Vara do Trabalho da Zona Leste-SP ruled on 22 Aug 2025 that operators must be present 'em todas as composicoes da Linha 15-Prata', 30 days to comply, daily fine of R$5,000, citing evacuation from a monorail viaduct about 15 m above the street.
src-4015d83e36d4edfa'O Tribunal Regional do Trabalho (TRT) acolheu, nesta terca-feira (2), um recurso apresentado pelo Metro', granting 'efeito suspensivo a decisao que determinava o retorno dos operadores embarcados'; automated running 'segue em vigor', 'sem operadores embarcados'.
src-98a14d800cf52547'A 8a Camara de Direito Publico do TJSP elevou de R$ 100 mil para R$ 500 mil a indenizacao coletiva a ser paga pela ViaQuatro'; 'o acordao e de 10 de maio'; equipment sat in platform doors at seven Line 4 stations and existed to capture reactions to advertising, not for security or train operation; damages go to the Fundo de Defesa de Direitos Difusos.
src-37aaf8f35102be35Plaintiff's account of the same case: first instance awarded R$100,000 in collective damages, raised to R$500,000 on the appeal of Idec, the Public Defender's Office and the Public Prosecutor's Office.
src-263637616ceebefcOperator states Line 5 trains are automatic because of CBTC but 'pode receber um upgrade' to driverless operation, which would require working platform doors. Basis for excluding Line 5 from the unattended count.
src-d25d3e4c0a809b18Six stations opened on 2 July 2026 in 180 days of 'operacao assistida' with 'circulacao controlada dos trens'; free travel, weekdays 10h-15h only; Acciona builds and the concessionaire operates for 19 years. No driverless claim is made, so Line 6 is not counted as unattended.
src-b490665c0db5a780The state operator publishes monthly passengers carried per line in open format; basis for the statement that ridership, not punctuality or headway performance, is what is actually published.
src-9de768c40c0c2446Peer-reviewed ethnography of Line 4 by Janice Caiafa (UFRJ). Line 4 was conceived for unattended operation (UTO), but the concessionaire keeps an assistance and maintenance agent aboard the automatic trains, posted at the front beside the hidden console and trained on a simulator to take manual control in an emergency; station staffing also stayed higher than the project planned. Fieldwork before 2021.
src-49c3e30f24b79341The Metro announces that Line 15 trains will no longer carry operators (OTs) and will move to GoA4 automation from August 2024, with operators withdrawn gradually and no dismissals.
src-2619c5170b251638Automatic operation on Line 15 began on Sundays from 18 August 2024 and extended to Saturdays from 7 September 2024; in this transition the train operators remained aboard.
src-d9c88973a4658079Supplier release marking ten years of Line 15, inaugurated on 30 August 2014.
src-4171dd8223b978f6Line 17 (Gold) monorail opened on 31 March 2026, designed for unattended operation (UTO) with CBTC; during the initial transitional phase staff accompany the trips while system reliability is checked.
src-2c969fc2ff33cda9Line 15's implementation contract, signed in September 2010 for Vila Prudente–Hospital Cidade Tiradentes, received its 19th amendment; the stretch from Jacu-Pêssego to Hospital Cidade Tiradentes remains under analysis.
