BEIJING - China has completed the construction of a powerful test bench for a train braking system, setting a world record by allowing a maximum test speed of up to 530 kilometers per hour, a railway researcher said Sunday.

Li Heping, a political adviser and researcher with the China Academy of Railway Sciences (CARS), said that as a key technology for high-speed trains, the test bench has been put into operation at a state key laboratory for the high-speed railway system at CARS.

The test bench can simulate the high-speed train braking process in different conditions like dry or humid environments, as well as airstream, low temperature and snowfall, Li told Xinhua on the sidelines of China's annual legislative session.

The CARS-developed high-speed train brake disc and brake lining have both passed tests at the new bench under maximum-speed conditions, said Li.
