Nanning (China), July 29 (Xinhua) Four people died and 34 were injured after a train derailed in south China's Guangxi Zhuang Autonomous Region early Wednesday, authorities said.

Train 1473, from Xiangfan of central Hubei province to Zhanjiang of Guangdong province, derailed at 4.22 a.m. in a valley in Liuzhou city of Guangxi.

The locomotive and its first four sleeper cars derailed, said the Nanning Railway Bureau.

Of the 34 injured, 11 were in serious condition, said Xiang Jun, a government official in Liuzhou.

Several hundred workers began efforts to clear rock and debris from the train track and used a large crane to lift the damaged rail cars.

The railway route linking Jiaozuo, central Henan Province to Liuzhou, was cut off.

Heavy rain had hit the northern and central parts of Guangxi from Monday to early Wednesday.

On June 29, two passenger trains collided in central Hunan Province due to a brake failure, leaving three people dead and 63 others injured.
