Violation

Between May 26 and May 28, 2025, the company underwent a safety audit conducted by the Kanto Transportation Bureau. The audit revealed areas requiring improvement, leading to an administrative guidance issued on September 17, 2025. The guidance specifies the following issues: 1. Facility Maintenance: The company has not conducted special inspections of the Sawaire and Kusaki tunnels as required by Railway Facility Standards Article 100, Paragraph 4, Item 2. Additionally, records of general inspections do not conform to prescribed formats, such as deformation expansion diagrams, and are recorded using non-compliant methods. The company must develop inspection plans for the tunnels lacking special inspections, ensure inspections are carried out, and update deformation diagrams after each inspection. 2. Vehicle Inspection: The company has not inspected vibrations, oscillations, abnormal noises, or axle heating of internal combustion engine vehicles as specified in Vehicle Structure and Maintenance Standards, Schedule 1, Item 67. The inspection methods for engine components like crankshafts, pistons, and cylinder heads also deviate from standards. The company must verify the validity of inspection items and methods, revise procedures as necessary, and ensure staff are properly trained. 3. Driver Training: Despite drivers sometimes operating trains or vehicles, the company has not conducted the required education and training programs as per Driver Operation Standards Article 6. The company must ensure appropriate training for drivers and manage staff to prevent untrained personnel from operating vehicles. 4. Operational Communication: The company has not issued operation notification tickets as required by Operation Standards Article 29, nor established procedures for radio or mobile phone notifications. The operation notification receipt tickets, which should be carried by crew members, are not being carried. The company must formalize procedures, ensure proper training, and enforce compliance. The company is instructed to report on the implementation of corrective actions by October 17, 2025.
