The world's fastest high-speed train is on the way. On 29 December, China displayed a prototype(样车) of the train. It marks a new era for the country's high-speed trains. The newest model is called the CR450. CR stands for China Railway. The CR450 is able to run at 450 kilometres per hour in tests. When it enters service, its speed is expected to reach 400 kilometres per hour. It's much faster than the CR400. The CR400 came out in 2017. It operates at 350 kilometres per hour.
The CR450 does well not just in speed. According to its developers, the train has shorter braking distances. It is also designed with greater stability. And all this helps ensure the safety of passengers.
In addition, the CR450 offers a quieter ride. The noise levels inside the train have been reduced. Meanwhile, cabin spaces have been increased so that passengers can enjoy more comfortable rides.
"The new train has been tested across several high-speed rail lines in China. It is not yet ready for commercial use, though. Further tests are needed." said the China State Railway Group(中国铁路总公司). "All tests are set to be finished within two years."
China is now the world leader in railway development. It has built the world's largest railway network. The network covers almost all corners of the country. The total length of rail tracks has reached over 160,000 kilometres. More than 46,000 kilometres are high-speed rail. The aim is to have 60,000 kilometres of high-speed rail by 2030. High-speed train has been an effective means of travel for long journeys as it allows people to travel around with ease and comfort.
