KORAIL suspended more than 120 trains [1], including KTX high-speed rail, at Seoul Station after debris from a collapsed viaduct blocked the tracks [1, 2].
The disruption represents a significant failure in urban infrastructure and transportation logistics, trapping thousands of commuters and halting critical transit links in South Korea's capital.
The suspension occurred on the third day of operational disruptions following the collapse of the Seosomun elevated road [1, 2]. Debris from the structure fell onto the railway lines, specifically impacting the north side tracks that lead to the vehicle depot [1, 2].
Korail said that the number of suspended trains for the day exceeds 120 [1]. The blockage has prevented trains from accessing essential maintenance and staging areas, creating a bottleneck at one of the region's busiest transport hubs.
Reports from the scene described a chaotic environment for travelers. Reporter Yoon Tae-in of YTN News said that electronic display boards at the station showed numerous cancellations, and announcements were made over the speakers to notify passengers of the service halts [1].
The collapse happened two days prior to the current report [1]. While the initial structural failure occurred earlier this week, the lingering debris on the tracks has prevented the restoration of normal rail traffic.
KORAIL officials have not provided a definitive timeline for the complete removal of the debris or the full resumption of all scheduled services. The company continues to manage the flow of passengers as the north side tracks remain impassable [1, 2].
“KORAIL is suspending over 120 trains, including KTX, for the day.”
The prolonged suspension of over 100 trains highlights the vulnerability of Seoul's integrated transport network, where a failure in road infrastructure can immediately paralyze the rail system. Because the debris blocked the path to the vehicle depot, the disruption is not merely a matter of track clearance but a systemic logistical failure affecting train positioning and scheduling across the KORAIL network.
