Violation

On November 27, 2024, it was revealed that Sagami Railway Co., Ltd. had operated a train with inspection records for the deceleration ability (measured deceleration data) that had been altered during the regular vehicle inspections (general and critical inspections) mandated by law. An audit conducted on December 5 and 6, 2024, confirmed the need for improvements, and directives were issued for corrective actions. The company must verify the appropriateness of its operational plans, methods, and management related to these issues, investigate the root causes including underlying factors, and develop measures to prevent recurrence, ensuring strict adherence to laws and regulations. The company is also instructed to improve the system so that data tampering becomes difficult, to systematically organize internal regulations regarding deceleration measurement methods and standards during test runs, and to implement education based on these regulations to manage test procedures properly. The corrective report is due by February 3, 2025. The violations involve the alteration of measurement data in the records of regular vehicle inspections, specifically related to the deceleration test during test runs, including those conducted in rainy weather, with no systematic internal regulations or manuals, relying instead on oral transmission. The enforcement authority is the Kanto Transport Bureau.
