Violation

On January 15, 2024, Minato Railway Co., Ltd. (corporate number 8040001053928), based in Ichihara City, Chiba Prefecture, reported to the authorities that one of its drivers (hereafter 'the driver') had operated a train or vehicle without conducting alcohol tests using an alcohol detector before duty, and that another person had substituted for the test, falsely passing it. An audit was conducted on January 17, 2024, which identified issues requiring improvement. The company was instructed to verify the appropriateness of operational methods, implementation status, and management related to these issues, investigate the root causes including underlying factors, and develop measures to prevent recurrence, ensuring the safety of railway transportation. The company was also asked to report on the corrective actions by March 8, 2024. Specifically, it was confirmed that the driver had repeatedly allowed a conductor to substitute for alcohol testing using an alcohol detector while the station staff was away, and on October 19, 2023, the driver turned off the alcohol detector during testing to avoid detection of alcohol, refusing re-test instructions and instead having the safety officer conduct the test. The guidance emphasizes the need for thorough safety awareness regarding alcohol consumption, compliance with laws and regulations, and the establishment of a system for accurate on-site situation awareness, with regular verification and improvement. Furthermore, the guidance references the interpretation standards for technical regulations related to railways, specifically regarding the education and training of personnel directly involved in train operations ('operation personnel'). It was confirmed that the company’s implementation guidelines do not specify necessary details for training and record-keeping, and that records of training are not maintained, making management and verification difficult. The company is instructed to include these details in their implementation guidelines, maintain records, and properly manage the training process. Failure to comply with these instructions, or if safety management improvements are not confirmed, or if violations recur, may result in orders for business improvement based on relevant legal provisions, including the Railway Business Act Article 23 and the Administrative Procedure Act Article 35, which authorize such measures when safety or public interests are deemed to be hindered. This guidance was issued by the Kanto Transport Bureau.
