CCTV footage of a train that was travelling through a region of the Guangdong province on Saturday has emerged.
The video, which was uploaded on the Weibo microblogging service, shows the train travelling on a stretch of the Qinghai-Tibet railway.
The video was uploaded to a Weibo account belonging to a man named Xu Zhijian.
The Guangdang Railway Department said the train, carrying passengers from Wuppernal suspension station to the Wenzhou-Zhongshan railway line, entered the area of the Wuppercat suspension railway at around 8:45pm local time (12:45am GMT).
A number of CCTV cameras are stationed on the train tracks, and the footage shows the driver driving the train at high speed.
The train had stopped at the station about 2km away from the railway tracks, a spokesman said.
The CCTV footage also shows the drivers of the train turning on the emergency lights, as they approach the suspension railway.
The spokesperson said that the drivers were not aware of the nature of the accident and did not realise that the train was stopped at their destination.
In February last year, an accident involving a train carrying passengers on a suspension railway derailed in the Guangxi Zhuang Autonomous Region, injuring a number of people.
The National Transportation Safety Board (NTSB) found that the cause of the incident was the failure of the suspension rails to maintain their correct position, the accident report said.
