The China-Europe Railway Express is a freight train service that connects various cities in China with cities in Europe. It was launched to enhance trade and economic cooperation between the two regions, providing a faster alternative to shipping goods by sea. The service covers multiple routes, linking major cities like Chengdu, Hamburg, and Madrid. This railway network significantly reduces transportation time, taking about 10 to 20 days for shipments, compared to several weeks by sea. It plays a crucial role in the Belt and Road Initiative, promoting connectivity and facilitating the movement of goods across continents.
