CHONGQING/GUIYANG -- A railway connecting Chongqing and Guiyang, two major cities in Southwest China, started operation Thursday.

CRRC Changchun is now one of the world's leading railway providers, including bullet trains and multiple electric units, as well as railway cars. It has exported more than 8,000 cars to 22 countries and regions, and signed export contracts worth over billion.
