A train operator’s four-minute restroom break caused delays for 125 trains in Seoul earlier this week, leaving hundreds of passengers late.
The incident occurred on Line 2 at around 8 a.m. when the conductor made an urgent stop at a station to use a restroom located on another floor.
The operator took 4 minutes and 16 seconds to return, triggering a ripple effect that led to train rescheduling. Many trains were delayed by 20 minutes or more. An engineer monitored the situation as the conductor left and returned to the train.
Circular line operators typically work two to three hours without breaks, and while portable toilets are available, staff sometimes must use restrooms located away from platforms.
Despite the disruptions, Seoul Metro managed the situation effectively, ensuring passengers experienced minimal inconvenience and reached their destinations.
