Violation

Machine-translated summary — verify against original

Between October 7 and 9, 2024, the Chubu Transportation Bureau conducted a safety audit of Oigawa Railway Co., Ltd. (corporate number 1080001013422) headquartered in Shimada City, Shizuoka Prefecture. The audit revealed that the company did not perform inspections of track material wear during switch inspections as required by Article 41 of the Civil Engineering Standards for Track Inspection. Additionally, the company exceeded the inspection cycle for the E34 electric locomotive as specified in Article 36 of the Vehicle Standards. Based on these findings, the bureau has issued administrative guidance, instructing the company to investigate the root causes, implement preventive measures, and report the actions taken by April 25, 2025. The company must ensure proper training, establish systems to monitor inspection compliance, and take necessary corrective actions to ensure safety standards are met.
