Three things to knowTwo rail disruptions hit the morning commute, including the Metro’s Line 1 and the commuter Line 7. São Paulo’s core story today is mobility under stress. The Metro reported a Line 1 (Blue) train failure that forced an evacuation and slowed operations. Line 7 (Rubi), which links Barra Funda to Jundiaí, reported another failure after an energy-system issue the day before. São Paulo’s city weather service said the early hours were stable, but rain should increase in coming days.
