Commuters wait for a train at City Hall Station on Seoul Subway Line No. 2 on July 4.NEWS1
A signal failure at Seoul National University Station on Seoul's Subway Line No. 2 caused a temporary suspension of service in both directions during Friday morning’s rush hour.
The signal went down around 7:50 a.m., halting train operations on Line No. 2 for about 20 minutes, according to Seoul Metro.
“A track switch alignment error occurred at Seoul National University Station,” a Seoul Metro official said. “Service resumed after the issue was resolved.”
Although the error was fixed by around 8:09 a.m., train intervals remained irregular and the metro continued operating at reduced speeds.
