Tokaido Shinkansen services were suspended between Hamamatsu and Nagoya stations early Monday, following a derailment involving two maintenance trains, with a resumption not expected until the evening.
Central Japan Railway, also known as JR Central, which operates the Tokaido Shinkansen Line, had earlier suspended a section of the line between Tokyo and Nagoya stations from the first train of the day.
JR Central said the resumption work is expected to continue until the evening and it was not clear when the services will be fully resumed.
