How many kilometers per hour does the high-speed rail travel? Revealing China’s speed compared with the world

As a milestone in modern transportation, the speed of high-speed rail has always been the focus of public attention. This article will combine the hot topics and hot content on the Internet in the past 10 days to analyze the current situation, technological breakthroughs and global comparisons of high-speed rail speeds.

1. Current situation of high-speed rail speeds in China

China's high-speed rail network covers the whole country, and its operating mileage ranks first in the world. Here are the current speed data for major lines:

2. Comparison of global high-speed rail speeds

Although China's high-speed rail is fast, it is not the only high-speed rail system in the world. The following is the ranking of high-speed rail speeds by country:

3. Technological breakthrough: CR450 new generation EMU

Recently hotly discussedCR450 EMUThe test speed exceeded 453 kilometers per hour, marking China's high-speed rail entering a new stage:

4. Balance between speed and safety of high-speed rail

Although higher speeds are technically possible, practical operational considerations include:

1.Energy consumption economy: Speed increased by 30%, energy consumption increased by approximately 50%

2.Track maintenance costs: The annual maintenance fee for a track with a speed of 350km per hour is 40% higher than that of a track with a speed of 250km.

3.fare acceptance: After the Beijing-Shanghai high-speed railway speed is increased to 350km/h, the ticket price will increase by 12%

5. Future Outlook

According to the "Outline of the Advanced Railway Planning for a Powerful Transportation Country in the New Era", China is promoting:

- Achieved by 2025400 kilometers per hourBusiness operations

- Research and Developmentmaglev train(The test speed has reached 600km/h)

- BuildIntelligent high-speed rail system, realize fully automatic control through 5G

Conclusion

From the operating speed of 350km/h to the test breakthrough of 453km/h, China's high-speed rail continues to refresh "China's speed". In the future, with the iteration of technology, the speed of high-speed rail will continue to break through the balance point between physics and economics, reshaping the global transportation pattern.
