Four workers dead after being hit by train in Japan

Four workers in Japan have died after being struck by a train at Shin-Kanuma Station, north of Tokyo, authorities say.

The collision happened around 10:46 local time (01:46 GMT) while the workers were removing weeds from the train tracks, local media reported.

When emergency services arrived at the scene three workers were trapped under the train, while one was on the platform, police said.

Train service has been suspended on the Tobu Nikko Line due to the accident, according to the railway company operating the line.

A passenger on the train told Japanese public broadcaster NHK that they heard a "strange noise" before the train made an emergency stop.

He said passengers were stuck on the train for a while as staff announced that they were investigating the noise.

The train involved in the collision was a limited express train, according to NHK. These are the second-fastest trains in Japan, after the Shinkansen, also known as the bullet train.

Usually there would be an employee stationed nearby to warn workers on the tracks of approaching trains - but it was unclear what the situation was like on Thursday morning when the accident happened, the Asahi Shimbun newspaper reported.
