Machine-translated summary — verify against original

Between September 4 and 6, 2023, the Yamagata Railway Company underwent a safety audit conducted by the Tohoku Transport Bureau. The audit revealed several issues requiring improvement: (1) failure to perform necessary maintenance on track switches despite inspection results indicating non-compliance with standards, and (2) failure to carry out required repairs on station platforms despite identified obstructions. The company is instructed to promptly address these issues, including conducting thorough investigations into the causes, establishing measures to prevent recurrence, and ensuring compliance with legal and technical standards. Additionally, the company must review and enhance staff education and allocate appropriate budgets for facility maintenance. The corrective actions are to be reported by March 28, 2024.
