"Extremely smooth!" said Iñigo Aguas Ardaiz from France. "I didn't feel at all that the speed had reached 350 kmh! The riding experience is comfortable and easy, and this technology is a masterpiece."

Ali Abdollahi, a representative from Iran, praised the service quality: "Everything is so comfortable, and the carriages are clean and tidy. I think China has the most advanced high-speed railway system in the world, which is really amazing!"

The China Academy of Railway Sciences and China Railway Beijing Group organized the technical visit for officials from the International Union of Railways (UIC), foreign diplomats, business executives and journalists.

The Beijing-Zhangjiakou High-Speed Railway is the world's first high-speed railway to fully integrate smart technology into its construction, equipment and daily operations. The railway uses advanced technologies, including big data analysis, artificial intelligence and China's Beidou Satellite Navigation System, throughout the entire line.

The railway's Fuxing trains feature automatic driving capabilities that reduce energy consumption by 7.77% per train, according to the operators.

The 174-kilometer line passes through major engineering projects such as the Juyongguan Great Wall Tunnel and crosses the Guanting Reservoir Grand Bridge. The engineering works illustrate China's capabilities in smart railway construction across challenging landscapes.

Since opening in 2019, the Beijing-Zhangjiakou High-Speed Railway has carried more than 67 million passengers, according to operator data. The improved transport capacity and services have strongly promoted the coordinated development of the Beijing-Tianjin-Hebei region.

The line connects to Taizicheng Station in Zhangjiakou, which served as a transportation hub during the 2022 Beijing Winter Olympics. Visiting representatives said they were impressed by the station's facilities and operation systems.

After touring the "Winter Olympics Eye" landmark — a distinctive feature at the Taizicheng Station — and a cultural exhibition hall, international delegates said they appreciated features including tunnel engineering and dispatching systems.
