Mainland authorities on Thursday said 11 people were killed and two others injured in the early hours of the morning, after a test train collided with maintenance workers on the track in Kunming, in southwest Yunnan province.

The train, which was testing earthquake detection equipment, hit workers on a curved section of track at the city's Luoyang Town railway station, the officials said.

The station in Yunnan province has resumed normal services, and the cause of the accident is being investigated, they added in a statement. (Xinhua/Reuters)
