A Japanese bullet train hurtling along at 280 kilometres (174 miles) per hour ran for nearly a minute with one of its doors completely open on Wednesday, its operator said.
The accident, due to human error, was a rare mishap for the Japanese "Shinkansen" bullet train which has a world-famous safety and punctuality record.
The Tokyo-bound Hayabusa No. 46 train screeched to an emergency stop in a tunnel shortly after leaving Sendai station in northeastern
Japan when the conductor saw a warning light that the door of the ninth carriage was open, East Japan Railway said.
