On September 22, smoke was reported at Ewha Womans University Station on Seoul's Subway Line 2, leading to a suspension of train services for over an hour. The smoke originated from a mechanical room.
According to the Seoul Transportation Corporation, smoke began to appear around 8:10 PM, causing all inbound and outbound trains to bypass Ewha Womans University Station starting at 8:24 PM.
During this incident, the safety doors malfunctioned, which was attributed to the smoke suppression efforts.
The fire department completed initial suppression efforts by 8:25 PM and fully extinguished the smoke by 10:12 PM. There were no reported injuries.
The smoke was traced back to the uninterruptible power supply (UPS) room located on the station's platform. This room houses equipment designed to provide stable electricity to the platform screen doors, ensuring they operate during power outages or voltage fluctuations.
After manually opening the safety doors, the Seoul Transportation Corporation resumed train operations in both directions at 10:12 PM.
The fire department is currently investigating the cause of the smoke and the malfunction of the safety doors.
