Tokaido Shinkansen bullet train services remain suspended between Nagoya and Hamamatsu stations following an accident involving maintenance vehicles.
The operator, Central Japan Railway Company, says the recovery work will continue until Monday evening and it cannot predict when trains will be able to use the affected section.
Central Japan Railway says a maintenance vehicle was rear-ended between Toyohashi and Mikawa-Anjo stations at around 3:30 a.m. on Monday. Both vehicles were derailed.
The driver of the vehicle that rear-ended the other one suffered a cut to his head and was taken to a hospital. A maintenance worker has a minor leg injury.
The operator is urging travelers not to use the Tokaido Shinkansen line until services are fully restored, to avoid congestion at stations.
