JR East to suspend E8 shinkansen trains for time being
East Japan Railway, or JR East, said Wednesday that it will suspend some services on the Yamagata Shinkansen train line, following malfunctions found on E8 series Shinkansen trains.
The railway operator said that it will halt individual operations of E8 trains until the cause of the trouble is identified.
On Tuesday, an out-of-service E8 train became unable to accelerate while traveling northward between Utsunomiya and Nasushiobara stations in Tochigi Prefecture, leading to a service suspension between Tokyo Station and Sendai Station in Miyagi Prefecture for about five and a half hours.
JR East said that a power supply device malfunctioned, causing the motor to stop working. The company added that three more E8 trains — two in service and one out of service — suffered issues during the service suspension.
The E8 series entered service last March. Nine trains are in operation, while two are undergoing test runs. The four trains that malfunctioned were the latest version, delivered in November last year and after.

JR East: Power supply system malfunction likely caused E8 Shinkansen shutdown
East Japan Railway says it believes an hours-long stoppage of one of its newest Shinkansen trains was caused by a malfunction in the system that supplies electricity to the train, which caused its motors to shut down. During a test run on Tuesday, an E8 series Shinkansen train stopped between Utsunomiya and Nasushiobara stations in Tochigi Prefecture. As a result, services on the Tohoku Shinkansen line between Tokyo and Sendai had to be suspended for more than five hours. East Japan Railway found that the power supply failure may have disrupted the train's motor cooling function, which triggered the safety system designed to prevent overheating. Also on Tuesday, an E8 train that stopped at Koriyama Station in Fukushima Prefecture and another moving through Fukushima City experienced problems. Additionally, a malfunction occurred on a train that stopped at Oyama Station in Tochigi Prefecture. East Japan Railway says it has confirmed that all four E8 trains experienced power supply system problems. The company says there are no major differences between the systems that supply power in the E8 series and other Shinkansen series. It says the E8 series will remain out of service until the cause of the malfunction is determined.
