A gale warning system is being developed to protect all train passengers, after a recent derailment left three people dead in western China.

 

The Ministry of Railways commissioned the warning system in response to the freak accident in the Xinjiang Uygur Autonomous Region last Wednesday, which left more than 30 passengers injured.

 

If successful, the system will be used across the country.

 

Currently only the Qinghai-Tibet Railway is equipped with a strong wind warning system, said Lu Zhizhong, an expert with the High-speed Railway Research Center.

 

The Qinghai-Tibet Railway's system involves a research center run by the Central South University in Changsha, Hunan Province, which gathers weather information for statistical analysis before sending warnings to train drivers according to their locations.

 

"In the case of the Qinghai-Tibet Railway, we send out warnings if the wind speed reaches more than 18 meters per second," said Lu.

 

So far, the center has sent at least 50,000 warnings, and the Qinghai-Tibet Railway has not experienced any accidents caused by strong winds.

 

However, for most railways, the local meteorological stations send the latest weather information to train dispatchers who then must use their own discretion to decide whether a train should run.

 

In areas with strong year-round winds, some special steps have been taken to ensure safety, such as installing wind-measuring facilities along railways in Xinjiang, which automatically collect wind data every three seconds and send it to train dispatchers.

 

But in general, China needs to improve the railways' strong wind warning system, say experts.

 

Lu said research into the effect strong winds can have on trains is behind where it should be, because trains running faster than 160 kilometers an hour, which are particularly prone to high winds, were only introduced to China in recent years.

 

Last Wednesday, 11 of the 19 cars of a passenger train on its way from Urumqi to Aksu in Xinjiang were knocked off the rails by the sudden gust of a 13 gale force wind.

 

The families of the three passengers who died in the derailment will each receive 200,000 yuan (US$25,800) in compensation from the Railways Ministry, the Beijing News reported, quoting a relative of victim Shi Lei.

 

The ministry yesterday refused to confirm the amount. According to railway compensation rules, each passenger, whether dead or injured, is entitled to no more than 40,000 yuan (US$5,170) in compensation.
