Chinese train manufacturer CSR Corp Ltd. has presented a new 500 km/h (310 mph) high-speed train. The world largest high-speed train consists of six cars, has a futuristic shape and a maximum tractive power of 22,800 kilowatts. The design of the train is inspired by the ancient Chinese sword. It is built of a plastic reinforced with carbon fibre and magnesium alloy for reducing weight and increasing the maximum speed of travel. The new train was built as a substitution to the existing high-speed trains in China that were travelling at about 300km/h until, in July 2011, the government of China has reduced the maximum allowed speed after the serious train accident where at least 40 people were killed and another 210 were injured.
The newly presented high-speed train is also part of the Chinese railway infrastructure improvement plan according to which 13,000 km (8,078 miles) of high-speed rail network should be built by 2012, and about 20,000 km (12,427 miles) by 2020. There is still no information when this train will be put into commercial use. Along with the new unveiled train, a high-speed railway linking Guangzhou, the capital of the southern province of Guangdong, to Shenzhen, city on the border with Hong Kong, started its service on Monday. The route to Hong Kong is planned to be extended by 2015.
