Between October 3 and 6, 2023, the Shikoku Transport Bureau conducted a safety audit of Tosa Kuroshio Railway Co., Ltd. The audit revealed issues requiring improvement, leading to an instruction for corrective actions. The company must investigate underlying causes, prevent recurrence, and report measures taken by January 29, 2024. Specific issues include: 1.

The company must promptly conduct pending tests and training, and review its training and management systems. 2. Non-repair of automatic train stop devices where test values fell below standard, and inadequate management of maintenance facilities. Repairs should be carried out immediately, and management systems improved. 3. Failure to measure control section length at a level crossing, and lack of record of signal light terminal voltage measurements at Kubokawa Station. Measurements should be conducted promptly, and inspection systems improved. 4. No records of periodic inspections of electric signals at Kubokawa Station.
