A partial collapse of the Seosomun Overpass in Seoul has resulted in multiple fatalities and significant interruptions to national high-speed rail services.

首爾西小門高架橋部分崩塌，已導致多人死亡，並造成國家高鐵服務嚴重中斷。

The incident occurred on Tuesday at approximately 14:31 in the Seodaemun-gu district during the demolition of a structure originally commissioned in 1966. The failure resulted in three fatalities—specifically the engineering company's chief supervisor, the site manager, and an external consultant—and caused injuries to three construction personnel. In response, the Seoul Western District Prosecutors’ Office has convened an eleven-member investigative task force, comprising four prosecutors and six investigators, to determine the causality of the collapse and identify liable parties. This body is coordinating with police and labor authorities, with a focus on the potential issuance of warrants should evidence of negligence emerge.

該起事故發生於週二約 14:31，地點位於西大門區，當時正在拆除一座原於 1966 年啟用之結構。此次失效導致三人死亡，死者分別為工程公司首席監工、工地經理及一名外部顧問，並造成三名建築人員受傷。對此，首爾西區檢察廳已召集由 11 名成員組成的調查專案小組（包含 4 名檢察官及 6 名調查員），以釐清崩塌原因並確定負責方。該小組正與警方及勞工主管機關協調，若發現有過失證據，將重點考慮發布逮捕令。

Concurrent with the legal inquiry, a forensic analysis was conducted between midnight and 04:00 by the National Forensic Service and the Korea Occupational Safety and Health Agency. The primary objective of this examination is to ascertain whether adherence to established safety manuals was maintained or if regulatory violations occurred. Should the findings indicate a failure to observe safety protocols, officials from the Seoul Metropolitan Government and the contracted construction firm may face criminal prosecution.

在法律調查的同時，國立科學搜查研究院與韓國職業安全健康署於午夜至凌晨 04:00 之間進行了鑑識分析。此次檢查的主要目的是確定是否遵守了既定的安全手冊，或是否存在違規行為。若調查結果顯示未遵守安全協議，首爾市政府官員及承包的建築公司可能會面臨刑事起訴。

Infrastructure damage extended to the railway network, as debris compromised power lines between Seoul and Sinchon Stations. Consequently, the Korea Railroad Corporation (Korail) reported that only 80.8 percent of train services remained operational on Wednesday. Over 120 KTX services across the Gyeongbu, Honam, Gyeongjeon, Donghae, and Jeolla lines were either suspended or rerouted. To mitigate passenger congestion at Seoul Station, Korail implemented temporary operational adjustments, including the utilization of Mugunghwa trains on specific segments and the requirement for certain KTX services to effect stops at all intermediate stations.

基礎設施損壞延伸至鐵路網絡，由於碎片損毀了首爾站與新村站之間的電力線。因此，韓國鐵道公社 (Korail) 報告週三僅有 80.8% 的列車服務維持運作。橫跨京釜線、湖南線、慶全線、東海線及全羅線的 120 多班 KTX 列車被暫停或改道。為了緩解首爾站的乘客擁擠，Korail 採取了臨時營運調整，包括在特定路段使用無窮花號列車，以及要求部分 KTX 列車在所有中間站停靠。

Rail operations remain partially suspended pending the completion of municipal recovery efforts and subsequent safety certifications of the power and track infrastructure.

在市政府完成復原工作以及電力與軌道基礎設施通過後續安全認證之前，鐵路運行將維持部分暫停。
