Train circulation resumes on Line 8-Diamante; Normalization should occur within 30 minutes, says concessionaire

Line 8-Diamante informs that train circulation has resumed and is in the process of regularization, with normalization expected within 30 minutes. Earlier, a traction failure in a train on the auxiliary track caused the interruption of circulation between the General Miguel Costa and Carapicuíba stations. During the incident, customers disembarked on the road and were accompanied by Customer Service and Security Agents (AAS) to the platform to continue their journey.

With the resumption of circulation, the activation of buses for the PAESE operation was cancelled.

A survey carried out by reporter André Graça, from TV Globo, shows that Line 8-Diamante is the one that recorded the most failures in 2026, with 39 occurrences between January and November, followed by Line 9-Esmeralda, with 34. The two lines are operated by the concessionaire ViaMobilidade. Considering all CPTM and ViaMobilidade lines, 185 occurrences were recorded this year, compared to 119 in the entire year 2025, an increase of approximately 55%, even without the end of 2026. Last year, Diamante and Esmeralda also led the survey, tied with 30 occurrences each.

The concessionaire responsible for Line 8-Diamante reported that train circulation is interrupted between the General Miguel Costa and Carapicuíba stations, in Greater São Paulo, due to a traction failure in a train that was on the auxiliary track. According to the company, passengers who disembarked on the tracks are being accompanied by service and security agents to the platform, where a train has been positioned so they can continue their journey. Circulation continues to be maintained on the other sections of the line, and 60 buses from the PAESE system were activated to serve the affected section. The concessionaire also stated that, for safety reasons, traffic will remain interrupted as long as there are passengers on the road.

Although ViaMobilidade reported that the failure on Line 8-Diamante began at 6:35 am this Thursday (12), passengers were already reporting problems with circulation before that time. According to reporter Hermínio Bernardo, from TV Globo, the first audible warnings at the stations about the occurrence were only made around 8 am, more than an hour after the time informed by the concessionaire for the start of the failure.

A passenger who was on the train that failed in Carapicuíba told reporter Hermínio Bernardo, from TV Globo, that she boarded at 6:10 am, when the train was already traveling slowly. According to her, the train stopped in the middle of the journey and remained without moving for about an hour, while passengers were experiencing shortness of breath and people were feeling ill. The woman managed to arrive at Barra Funda station, in the West Zone of São Paulo, at around 8:20 am.
