D
The world's fastest high - speed train is on the way. On December 29, 2024, China showed a test model of the train. It marks a new age 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 starts carrying passengers, its speed is expected to reach 400 kilometres per hour. It's much faster than the CR400 model. The CR400 came out in 2017. It runs at 350 kilometres per hour.
The CR450 does well not just in speed. According to its developers, the train can also stop more quickly and stays more stable (平稳). All this helps to make sure of passengers' safety.
In addition, the CR450 offers a quieter ride. The noise levels inside the train are lower. Meanwhile, the seats have more space 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 public use, though. Further tests are needed, said China State Railway Group. 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 rail length has reached over 160,000 kilometres. More than 46,000 kilometres are high - speed rail. The goal is to have 60,000 kilometres of high - speed rail by 2030.
High - speed rail has been a great way to travel for long journeys as it allows people to travel around easily and comfortably.
