Last year, eight investment enterprises operating within the rail transit industry chain in Southwest China's Chongqing obtained 185 new orders, amounting to 42.4 billion yuan ($5.78 billion). These orders included international contracts from Mexico, said Chongqing City Transportation Development & Investment Group.

According to Jiang Xiongjie, the deputy chief economist of Chongqing CRRC Times Electric Technology, the Chongqing-made rail transit system is being deployed on Line 4 in Guadalajara, the capital of the west-central state of Jalisco, as well as on Line 4 and Line 6 in Monterrey, the capital of the northeastern state of Nuevo León, Mexico.

In the case of Guadalajara's Line 4, the company is delivering components for a project to integrate a power supply system. The line is expected to be completed within this year.

Chongqing CRRC Times Electric focuses on researching and developing environmentally friendly, low-carbon technologies for rail transit and the industrializing of associated equipment. Its businesses span more than 40 cities and 18 railway bureaus in China, with its related products having been applied on over 100 rail transit lines.

Chongqing is positioning itself as a world-class rail transit city. It is said to have established the world's largest rail transit network in a mountainous area.

As of Jan 2, the city's operational rail transit network has expanded to 575 kilometers, the Chongqing Commission of Housing and Urban-Rural Development said.
