How many kilometers per hour does the train travel: A complete analysis of the speed of high-speed rail and regular trains around the world

In recent years, the rapid development of high-speed rail technology has made train speed a hot topic of public concern. From China's "Fuxing" to Japan's "Shinkansen", train speeds in various countries continue to set new records. This article will combine the hot topics on the Internet in the past 10 days, conduct a structured analysis of global train speed data, and explore the trends behind the technology.

1. Ranking of major high-speed rail speeds in the world

Note: Some countries are testing higher speeds (for example, China's CR450 test speed reaches 450 kilometers per hour), but actual operations are still subject to safety restrictions.

2. Comparison of the speed of regular trains and freight trains

3. Correlation analysis of recent hot topics

1.“Magnetic levitation technology” sparks heated discussion again: Japan’s Chuo Shinkansen (maglev) test speed exceeded 603 kilometers per hour and is expected to be commercially available in 2027, triggering expectations for the next generation of high-speed rail.

2.“Green transportation” becomes the focus: France announced that it will fully switch to renewable energy for TGV in 2024. The energy consumption of high-speed rail is only 1/4 of that of aircraft, which is in line with the goal of carbon neutrality.

3.China’s new record for “high-speed rail mileage”: As of 2023, China's high-speed rail operation mileage will reach 42,000 kilometers, accounting for 2/3 of the world. Netizens are hotly discussing the efficiency of the "eight horizontal and eight vertical" road network.

4. Technical bottlenecks and future trends

Currently, improving train speed faces three major challenges:Rail friction loss,Air resistance increases exponentially(Energy consumption surges when the speed exceeds 400 kilometers per hour),cost control. In the next ten years, superconducting magnetic levitation and vacuum pipeline technologies may become breakthrough directions.

It can be seen from structured data that train speed is not only a technical indicator, but also reflects the layout of various countries' transportation strategies and environmental protection policies. Next time you take a high-speed train, you might as well pay attention to the scenery outside the window - they are witnessing the miracle of human engineering at a speed of 300 kilometers per hour.
