A train on Line 1 had to be stopped after a technical problem arose between Namyeong Station and Yongsan Station at around 7:35 p.m., forcing passengers to change to the next train. The next three trains had to stop for roughly 17 minutes.
|Subway Line No. 4 also suffered glitches in electricity supply, Aug. 28 (Yonhap)|
Earlier in the day at around 11:20 a.m., a train departing from Hongik University Station to Sinchon Station on Line 2 lost power on its main circuit and suffered a 2-minute blackout.
Emergency measures by the train staff helped minimize service disruption, but the train was pulled out of service at Seongsu Station, where a substitute train took its place.
