According to Diário do Transporte, train circulation on Line 9-Esmeralda in São Paulo was restored on the morning of Wednesday, 4 November, between Presidente Altino and Ceasa stations. The interruption followed a failure at a power substation in Osasco.
What happened
The disruption stopped trains on a section of the line. According to ViaMobilidade, the concessionaire responsible for Line 9-Esmeralda, maintenance teams worked on the equipment at the Osasco substation to resolve the problem. With the work completed, trains returned to service on both tracks in the affected section.
Current service
Although trains are running again, the operation is still going through a process of regularizing the intervals between train movements. In other words, the spacing between trains is being adjusted back to normal, as stated by ViaMobilidade. The information released so far does not indicate how long this adjustment will take.
What passengers should know
The available information covers only the section between Presidente Altino and Ceasa. It does not mention replacement buses, alternative routes or changes at other stations on the line. Passengers travelling on Line 9-Esmeralda, especially on this stretch, may want to check the latest updates from ViaMobilidade before and during their trips.
Diário do Transporte reported the event as a short-term disruption linked to a single equipment failure, and the operator's statements point to a return to regular service once the spacing between trains is fully regularized.
