Violation

Konan Railway Co., Ltd. was subject to administrative guidance by the Tohoku Transport Bureau on January 23, 2024, following a derailment incident on August 6, 2023, on the Owani Line between Owani Station and Shukugawara Station. The incident's cause is under investigation by the Transport Safety Board, but post-accident inspections revealed that rail wear had reached replacement thresholds. An audit conducted on December 13-15, 2023, identified multiple deficiencies in track inspection, maintenance, and management, including visual-only rail wear inspections without proper measurement tools, failure to repair exceeding gauge and rail wear issues, and lapses in train sway and track displacement inspections. Additionally, issues with platform clearance and track patrols were noted. The guidance requires the company to implement corrective measures, verify the appropriateness of operational plans, and strengthen maintenance management systems, including staff training and external expert engagement. The company must report on these measures by February 22, 2024. Failure to improve safety management or repeated violations may result in orders to improve business operations under relevant laws, including the Railway Business Act and Administrative Procedure Law.
