Lower air resistance

When the bullet train runs at 350 km/h, 90 percent of the resistance comes from the air. Compared with previous versions of bullet trains in China, the Fuxing train has an improved aerodynamic performance.

The resistance has been reduced by 12 percent and the energy consumption per 100 kilometers per capita has been cut 17 percent, according to Ding Sansan, the deputy chief engineer of the CRRC Sifang Co Ltd, the bullet train's manufacturer.

It is equivalent to a reduction of 5,000 kilowatts of electricity on a Beijing to Shanghai trip, said Ding.
