In the first quarter of the year, the Erenhot Railway Port, a key hub on the "middle corridor" of the China-Europe Railway Express, handled a record-high 1,145 freight train trips, a 22.3 percent increase from last year.

Cargo volumes also rose steadily, with the port transporting 110,200 twenty-foot equivalent unit (TEU) containers and 946,400 tonnes of goods in first three months, up 14.6 percent and 19.7 percent year on year, respectively.

The railway network serves as a major platform for the Belt and Road Initiative. It consists of western, eastern, and middle corridors, and has been expanding its reach across Eurasia in recent years. In January, a new route linking Russia's Solombarka and Weizi Town in north China's Shanxi Province was launched via Erenhot, bringing the total number of routes to 75.

The network now connects to more than 70 logistics hubs in over 10 countries, including Germany and Poland, while linking with most major China-Europe freight train departure cities nationwide.
