Seoul Metro temporarily sent Line 5 trains through Yeouinaru Station without stopping on September 5 as crowds converged on Yeouido for the 2026 Seoul World Fireworks Festival. The station sits close to the Hangang Park event area, making it one of the main access points for spectators arriving by subway.
The non-stop measure began after crowd density around the station increased in the early evening. Such measures are used when allowing more passengers to enter or exit a station could create unsafe congestion on platforms, stairs or nearby streets. For riders, the immediate effect is clear: they must use neighboring stations and continue on foot or change their route.
Crowd control changes the commute
The disruption illustrates the operational challenge created by large events in Seoul. A festival can attract huge numbers of people into a relatively small area within a short window, while normal subway service is designed around more distributed demand. Crowd-control decisions therefore need to change in real time as pedestrian flows shift before and after the main event.
For people attending the festival, the safest travel plan is to expect station controls, longer walking distances and delays. Nearby stations can also become crowded as passengers divert away from Yeouinaru. The transport impact can continue after the fireworks end because many spectators leave at roughly the same time.
City operators must then manage the transition back to normal service without creating a second congestion point elsewhere. Clear station announcements, alternative-route guidance and staggered crowd movement help distribute passengers across the network as conditions around Yeouido improve.
