The design of China's hyperloop transportation system that can travel at a speed of 1,000 kilometers per hour has been fixed by the China Aerospace Science and Industry Corp (CASIC), one of the nation's major space contractors.

The carriage body is 29 meters long and three meters wide, using light and heat preventing material to reduce its weight.

The hyperloop will be a maglev line on which a pod will travel on partly elevated tubes or tunnels at superfast speed reaching 1,000 km per hour.

The research team is expected to tackle the key technology by 2020, said Wang Yan, staff at the CASIC.

It will launch speed test of 1,000 kilometers per hour by 2023 and be capable in full-system manned design by 2025.

CASIC is the first Chinese enterprise and the world's third, following the United States' Hyperloop Transportation Technologies and Hyperloop One, that has started developing hyperloop transportation system.
