East Japan Railway is investigating the decoupling of two Shinkansen bullet trains running in Tokyo on Thursday morning. The linked Hayabusa and Komachi trains on the Tohoku Shinkansen line became separated at around 11:30 a.m. while traveling between Ueno and Omiya stations in Tokyo and Saitama Prefecture. The decoupling caused an automatic brake to activate and the trains came to a stop on the tracks. Passengers going to Akita will have to change trains at Morioka Station, and those to Yamagata at Fukushima Station. The government’s Transport Safety Board says it will investigate the case as a serious incident that could have led to a major accident. (Ref.NHK WORLD-JAPAN)
