The correct answer is option C: China's latest high-speed train model, the CR450, reached a speed of 450 km/h during a test run from Tianjin to Beijing on December 25, 2024. The letters "CR" stand for China Railway, and the number "450" ​​refers to the operating speed. This is considered the fastest high-speed train in the world today. The CR450 is undergoing extensive testing, paving the way for commercial operation, possibly in 2025.

2. What speed can the CR450 reach in commercial operation?

  450 km/h

The correct answer is option B: According to China Railway Corporation, the CR450 can operate at 400 km/h in commercial operation. This is still significantly faster than the current Fuxing CR400, which runs at 350 km/h. Compared to the CR400, the CR450 is 12% lighter, consumes 20% less energy, and has a 20% improvement in braking performance.

  Shinkansen high speed train, Japan

The correct answer is A: Harbin-Dalian is the world's first high-speed railway that operates at low temperatures in winter. The line is 921 km long, running through three provinces in northeastern China at a design speed of 300 km/h. It passes through areas where temperatures can drop to -40 degrees Celsius in winter. The line is equipped with electric heating systems and snow-melting equipment on the road or at curves. If there is too much snow, the operator will turn on the electric heating system and manually clear the snow so that the train can run normally.

4. Which country has the longest high-speed railway in the world?

  Japan

The correct answer is A: In 2012, China broke the world record when it officially put into operation the high-speed railway connecting Beijing with Guangzhou - the capital of Guangdong province. The total length of the line is nearly 2,300 km, reducing travel time from more than 20 hours to about 8 hours with a maximum speed of up to 350 km/h.

5. How fast is the world's first cross-sea high-speed railway?

  450km/h

The correct answer is A: The 277-kilometer Fuzhou-Xiamen Railway connects Fuzhou and Xiamen, two major cities in Fujian Province, reducing the travel time between the two cities from 1 hour and 50 minutes to just 55 minutes. The line has a designed speed of up to 350 km/h and has 8 stations along the way. According to China Daily, the line passes through three newly built cross-sea bridges in Quanzhou, Meizhou and Anhai Bay. As the world's fastest cross-sea railway, it will take only 98 seconds to cross the 9.5-kilometer Anhai Bay Bridge. The most difficult part of the construction is ensuring that the high-speed train runs stably on the bridge despite the complex marine environment.

  France

The correct answer is A: Spain joined the high-speed train race in 1992, using technology imported from France. Since then, the country has developed super-fast trains and built Europe's largest long-distance rail network, stretching from Madrid to Seville, Malaga, Valencia, Galicia and Barcelona. Spain has more than 3,600 km of rail dedicated to trains running at speeds of over 250 km/h.
