Overview

  • A suspected short circuit caused an explosion and fire on a Line 12-Safira train on Thursday, July 23, forcing passengers to evacuate onto the tracks and creating major service disruption with no reported injuries.
  • Regulator Artesp suspended Trivia Trens’ exclusive operation on Friday for up to 90 days and ordered the Companhia Paulista de Trens Metropolitanos (CPTM) to resume running Lines 11, 12 and 13 and the Expresso Aeroporto to restore safe service.
  • Authorities launched multiple reviews: Artesp opened administrative proceedings that may lead to penalties, the Tribunal de Contas do Estado (TCE-SP) demanded clarifications within five days, and a joint committee including the operator and the train manufacturer will investigate technical causes.
  • Governor Tarcísio de Freitas warned the concession could be revoked if Trivia Trens fails to meet contract obligations, signaling possible contractual sanctions or caducity depending on investigation findings.
  • The transfer back to CPTM affects routes that carry almost 1 million passengers per day and follows a 2025 R$14.3 billion, 25-year concession that had moved to exclusive private operation only days earlier on July 21.
