(Yicai Global) Dec. 23 -- CRRC has debuted the world's fastest cargo trains that can reach a speed of 350 kilometers per hour in northern China.

The state-owned rolling stock manufacturer launched the new technology in Hebei province's Tangshan today, the Paper reported.

It took more than three years for the Beijing-based firm's Tangshan unit and its partners to develop the super-fast technology. The carriages will be used in freight transport with a range from 600 kilometers to 1,500 km.

The coaches can carry at least 110 tons, or over 800 cubic meters of cargo. The related utilization rate is 85 percent. The units have been installed with 2.9 meter-wide doors, resulting in the widest cargo train exits.

The high-speed trains feature mobile data connectivity and make use of China's BeiDou Navigation Satellite System to help load and unload cargo accurately.
