Subway troubles blamed on electrical problem

Two trains on subway line No. 2 in Seoul stopped operating temporarily yesterday morning because an overhead wire that powers the trains malfunctioned, officials said.

Seoul Metro said bitter cold weather could have caused the problem.

One train stopped at 6:50 a.m. en route from Mullae Station to Yeongdeungpo-gu Office Station. Seoul Metro immediately mobilized mechanics and finished repair work at 7:40 a.m. The train restarted right after.

But at 8:05 a.m., another train stopped at the same spot and a repair team worked for 35 minutes until the train restarted.

Meanwhile, all trains between Sindorim Station and Hongik University Station were ordered to stop until the repair work was completed.

The single problem spot caused a long back up on line No. 2 and it was 9:30 a.m. before all trains were operating as usual.

“The electricity line, which provides power to the train, seems to have had a problem,” said Sim Jae-chang, an electricity-team official at Seoul Metro. “The exact reason the trains halted hasn’t been clarified yet, although we assume the cold spell caused the problem.”

Commuters, trying to get from place to place during rush hour, complained about the service disruption.

“I was stuck for almost 40 minutes,” said Kim Seong-min, 32. “When the train restarted, I got off the train [at the next station] right away and got out to take a cab. But there were so many people like me [outside] so it was not easy to get a cab.”

Seoul Metro said yesterday that it will issue certificates for all commuters in the stopped trains, as long as they prove they were late for work because of the malfunction.

“We will conduct further inspections on the two trains and electricity lines tonight, after all subway operations finish,” said Kim Ran, a Seoul Metro public relations official.

2호선 운행중단 원인은 `전차선`..한파때문

18일 오전 서울 지하철 2호선 운행 중단 원인은 열차 위에 있는 ‘집전장치’가 아니라, 영등포구청역 ‘전차선’ 문제로 밝혀졌다.

‘전차선’(electric car line)은 전기철도 전차에 전기를 공급하기 위해 팬터그래프(pantograph) 등의 집전장치에 직접 접촉하는 전선이다.

서울메트로 관계자는 “오늘 오전에 멈췄던 두 열차는 전차선에 문제가 있는 것으로 조사 결과 드러났다. 전선의 일정 구간에 전력 공급이 끊겨 열차가 멈췄다” 면서 “일부 보도된 ‘집전장치’ 문제는 아니다”고 해명했다.

한파로 인해 전차선에 전력 공급이 끊긴 것이냐는 질문엔 "계속되는 한파가 고장 원인을 끼칠 가능성이 있다"면서 "정확한 원인은 조사를 더해봐야 안다"고 답했다. …
