A tree fall halted train service on Line 8-Diamante, operated by Via Mobilidade, on Tuesday evening (January 20), between Antônio João and Barueri stations in Greater São Paulo. The incident, triggered by strong winds, prompted the activation of PAESE (Emergency Support Plan between Companies) buses to ferry passengers. Riders reported crowds and delays on social media.
Train service on Line 8-Diamante was suspended around 8 p.m. on Tuesday (January 20, 2026) after a tree fell onto the overhead lines between Antônio João and Barueri stations in Barueri, a city in Greater São Paulo. Via Mobilidade, the operator, attributed the issue to adverse weather conditions, including strong winds that gusted up to 55.6 km/h in the city, as recorded by the São Paulo City Emergency Management Center (CGE). The strongest gust hit the Guarapiranga dam in M'Boi Mirim at 6:20 p.m., while Campo de Marte Airport in Santana reported 42.6 km/h at 5 p.m.
Via Mobilidade teams were dispatched to clear the tree and restore operations, though no timeline for full resumption was provided. In the meantime, PAESE buses were deployed to assist stranded passengers on the affected stretch. The disruption caused crowds at stations and sparked complaints on social media. One X (formerly Twitter) post from Ana Vitória vented frustration: "Parabéns via mobilidade, a gente espera o ruim e vocês entregam o PIOR!!!!!!! PÉSSIMOSSS".
Weather in São Paulo stayed unstable that evening, with intermittent drizzle, but no conditions for heavy rain, per the CGE. Such interruptions underscore the vulnerabilities of public transport in metropolitan areas prone to weather events, particularly winds that can topple trees near rail lines. No injuries were reported, but the incident highlights the need for preventive maintenance on overhead infrastructure.
