Train service on the Gyeongui Line, which had been suspended after the collapse of the Seosomun overpass in Seoul, resumed on the 30th. Service on the Seoul–Cheongnyangni section of the Gangneung Line and Jungang Line KTX-Eum also returned to normal, gradually restoring the rail network.
According to Korea Railroad Corporation (KORAIL), KTX No. 405, which departed Haengsin Station in Goyang, Gyeonggi, at 6 a.m. that day, was the first to pass through the Seosomun section after repairs. The train passed near the accident site at around 6:18 a.m. and arrived at Seoul Station.
Gyeongui Line commuter trains bound for Seoul Station, departing Munsan Station and passing through Ilsan, Haengsin, and Sinchon, also began normal operations from the first train that morning.
After Seoul City completed demolition work, rail authorities worked through the night to restore catenary poles, string overhead lines, install cables, service signal equipment, and inspect track safety. They then deployed work cars and test trains to check for facility issues before resuming service.
The Seoul–Cheongnyangni section of the Gangneung Line and Jungang Line KTX-Eum also returned to normal service starting that day. KORAIL expects most train operations to normalize from the 31st as trains that have completed maintenance are deployed in sequence.
The metropolitan rail network is currently operating normally. However, some trains are still undergoing schedule adjustments. As of the 30th, total train runs are 643, 115 fewer than the usual 758. The operating rate is 84.8%.
High-speed trains decreased from the usual 397 runs to 341, leaving 56 runs not operating, with an expected operating rate of 85.9%. Conventional trains such as ITX-Saemaeul, ITX-Maum, and Mugunghwa dropped from 361 runs to 302, with the operating rate expected at 83.7%.
KTX trains, which had made temporary stops at all stations after the accident, returned to their regular stopping patterns from that day in line with the existing timetable.
KORAIL asked passengers to check train operations in advance via the KORAIL Talk application, its website, and the rail customer center. Tickets affected by schedule adjustments can be refunded without penalties, and tickets paid by credit card will be refunded automatically.
