Machine-translated summary — verify against original

On October 30, 2024, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) issued administrative guidance to Tokyu Corporation (東急電鉄株式会社) following an audit related to safety inspections of railway vehicles. During the process of emergency inspection of railway wheel axles initiated on September 12, 2024, reports emerged that Sogo Vehicle Manufacturing Co., Ltd. (株式会社総合車両製作所) had altered work records improperly. Such record modifications undermine the safety assurance system and are unacceptable. The audit revealed the following facts: 1. Actual conditions regarding regulations: - The contractor performed wheel axle pressing operations without adhering to internal safety management regulations. - The contractor lacked regulations on pressing force values and procedures for deviations, instead verifying or calculating pressing force values independently. 2. Actual conditions at the site: - Use of deviated wheel axles was orally and tacitly accepted over a long period. - The contractor believed deviations in pressing force were acceptable. 3. Staff knowledge and training: - No systematic education on wheel axle assembly was provided. 4. Record modification practices: - Record modifications were possible and had been carried out. - Such modifications were orally and tacitly accepted. 5. Management practices: - Supervisors did not verify the appropriateness of wheel axle usage. These facts violate the Railway Business Act and the Ministerial Ordinance on Technical Standards for Railways. Based on these findings, MLIT instructed Tokyu Corporation to take the following corrective actions: (1) Develop internal regulations for pressing operations. (2) Improve management of staff education and training. (3) Establish systems to prevent record modifications, including internal audits. (4) Review safety management systems across other operations. Reporting deadlines are January 31, 2025, for actions (1)–(3), and March 31, 2025, for action (4).
