東北新幹線、一時全線ストップ　ポイント故障、２．７万人影響―ＪＲ東

　１３日午前５時半ごろ、東北新幹線郡山駅（福島県郡山市）構内の上下線で、線路の向きを切り替えるポイントが作動しないトラブルが起きた。ＪＲ東日本によると、ポイントごと交換する作業を進め、同新幹線は東京―新青森間の上下線で一時運転を見合わせ、午後０時半ごろ全線で運転再開した。
　ＪＲ東は当初、運転再開見込みを午前７時１０分ごろとしていたが、ポイントのモーターが故障していることが判明し、復旧作業が難航。約３時間にわたって全線で運行をストップし、午前１０時ごろ東京―郡山間、仙台―新青森間でそれぞれ折り返し運転を始めた。
　このトラブルにより、上下線４９本が運休、２０本で最大６時間の遅れが発生。秋田新幹線が東京―盛岡間、山形新幹線が東京―福島間で運転を見合わせたほか、上越、北陸新幹線でも遅れが発生し、影響は計約２万７４００人に及んだ。（2022/01/13-18:32）

A railway switch problem forced a temporary halt to all inbound and outbound services of East Japan Railway Co.'s Tohoku Shinkansen Line, which links Tokyo and the Tohoku region of northeastern Japan, on Thursday.
   According to the company, better known as JR East, the railway point at Koriyama Station in Fukushima Prefecture was found not functioning around 5:30 a.m. (8:30 p.m. Wednesday GMT).
   The company entirely halted operations on the bullet train line between its two terminals--Tokyo Station and Shin-Aomori Station in Aomori Prefecture. Services became available on all sections by around 12:30 p.m. after the problem was fixed.
   JR East initially said that operations would be resumed around 7:10 a.m. But a motor for the railway switch was found out of order, making service restoration work tough.
   After the high-speed train line was fully suspended for about three hours, services resumed partially, between Tokyo and Koriyama, and between Sendai Station in Miyagi Prefecture, north of Fukushima, and Shin-Aomori, around 10 a.m., according to JR East.
