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 that despite multiple locations exceeding the maintenance standard values for track displacement and building clearances, necessary repairs and maintenance had not been carried out. The company is instructed to promptly perform the required maintenance, review and improve staff education and internal procedures, and establish an appropriate maintenance management system, including budget considerations. The company must also thoroughly investigate the root causes of these issues and implement measures to prevent recurrence, ensuring the safety and reliability of railway operations. The company is required to report on the corrective measures by March 28, 2024.
