The Companhia Paulista de Trens Metropolitanos (CPTM) has resumed temporary operation of three commuter-train lines in Sao Paulo following a system-wide shutdown [1].

This intervention marks a significant reversal in the privatization of the city's transit infrastructure. The state government ordered the takeover after severe operational failures compromised public safety and disrupted the metropolitan region's transport network [2].

The emergency measures affect lines 11-Coral, 12-Safira, and 13-Jade [1]. These lines were previously under the management of the private concessionaire Trivia Trens [2]. According to reports, CPTM intervened just three days [1] after Trivia Trens had taken over the operation of these services.

Chaos erupted on June 23, 2026 [2], when a short-circuit caused a fire on a Line 12 train [1]. The incident led to a total shutdown of the affected lines, leaving thousands of commuters stranded and creating widespread transit instability across the city [3].

CPTM will now manage the operations for a period of 90 days [1]. This window is intended to stabilize the service and address the technical failures that led to the fire and subsequent chaos [2]. The state government's decision to revert to public management underscores the urgency of restoring reliable transport to the metropolitan region [3].

Officials have not yet detailed the long-term status of the contract with Trivia Trens, but the current priority remains the immediate restoration of safety standards on the rails [2].

“CPTM intervened just three days after Trivia Trens had taken over the operation.”

The rapid failure of the private concession and the subsequent return to state control highlight the risks associated with the fast-tracked privatization of critical urban infrastructure. When a private operator fails to maintain basic safety and operational standards—resulting in a catastrophic event like a train fire—the state must act as the ultimate guarantor of public service, potentially complicating future privatization efforts in Brazil's transport sector.
