English summarySagami Railway Co., Ltd. was found on November 27, 2024, to have operated a train with falsified measurement data related to deceleration capability in the records of periodic vehicle inspections (general and critical inspections), specifically during test runs. An audit conducted on December 5 and 6, 2024, revealed deficiencies in the management of inspection records and internal regulations concerning deceleration measurement methods during test runs, including those conducted in rainy weather. The audit confirmed that the measurement records had been altered, and that procedural frameworks for verifying deceleration in various conditions were lacking, relying instead on oral transmission. The authorities have instructed the company to implement measures to prevent record falsification, establish systematic internal regulations, and improve staff training to ensure proper test procedures. The company must report on these corrective actions by February 3, 2025. The legal basis for this action is the Ministerial Ordinance on Technical Standards for Railways.
