DUISBURG, July 22, 2016 (Xinhua) -- Cargos are piled at Intermodal Terminal DIT in Duiburg, Germany, July 13, 2016. As many as 8 cargo trains from China arrive at this terminal every week, carrying Chinese products to Europe. Cargo trains were a logical development, opening a new channel for the transfer of goods to and from China's central and western regions to compete with the traditional maritime route from the east coast. A total of 16 cities now have regular cargo trains to Europe. (Xinhua/Yan Feng)
