More than 120 high-speed KTX trains have been canceled or rerouted across the greater Seoul area on Wednesday after a section of an aging overpass collapsed.

A part of the Seosomun Overpass in Seodaemun District, western Seoul, collapsed during demolition work on Tuesday, killing three people and injuring three others.

The falling structure struck overhead electric lines between Seoul Station and Sinchon Station, causing a power outage.

As a result, and with restoration work expected to take considerable time, Korail said it would suspend KTX services between Seoul Station and Haengsin Station in Goyang, Gyeonggi, and Gyeongui Line commuter services between Seoul Station and Susaek Station in northwestern Seoul, throughout Wednesday.

KTX trains on the Gyeongbu line will only run between Seoul Station and Busan Station, while trains on the Honam line will run between Yongsan Station and Mokpo Station or Yeosu Expo Station in South Jeolla. On the Gangneung line, KTX service will only operate between Cheongnyangni Station in eastern Seoul and Gangneung Station in Gangwon, while trains on the Jungang line will run between Cheongnyangni Station and Bujeon Station in Busan.

Services on the Gyeongjeon, Donghae and Jeolla lines — including the 5:13 a.m. KTX from Seoul Station to Busan — have also been suspended or rerouted.

All KTX trains are slated to make temporary stops at stations they would not normally serve, and delays are expected. Passengers are advised to check the status of their trains before traveling.

To mitigate congestion, Korail said it will operate intercity Mugunghwa trains on the Gyeongbu Line running between Daejeon Station and Busan Station; Honam Line Mugunghwa trains between Seodaejeon Station and Mokpo Station or Yeosu Expo Station; and Janghang Line services between Iksan Station in North Jeolla and Cheonan Station in South Chungcheong.

Also, all high-speed ITX-Saemaeul and ITX-Maeum trains will depart from and arrive at Suwon Station in Gyeonggi.

Seoul Subway Line 1 and the Gyeongui-Jungang Line between Munsan Station in Gyeonggi, Yongsan Station and Yongmun Station in Gyeonggi, are operating normally. The Gyeongui Line is running between Munsan Station and Susaek Station, but the Seoul Station to Susaek section remains suspended.

Korail said it would inspect overhead electric lines, rails and electrical and signaling equipment as soon as restoration work by the Seoul city government is complete, before deciding whether normal services can resume.
