International rail transport refers to the movement of goods and passengers across national borders using trains. It plays a crucial role in global trade by connecting different countries and facilitating the efficient transport of products. Rail networks often link major cities and industrial regions, making it a preferred choice for heavy and bulk cargo. Many countries have established agreements to streamline cross-border rail services, enhancing cooperation and reducing transit times. Notable examples include the Trans-European Transport Network in Europe and the China-Europe Railway Express, which promote economic ties and improve connectivity between nations.
