The six-car train with a fairshaped head is the newest in the CRH series. It has a maximum tractivepower of 22,800 kilowatts, compared with 9,600 kilowatts for the CRH380 trains currently inservice on the Beijing-Shanghai High-Speed Railway, which hold the world speed record of 300 kmper hour.

The grey-color train carrying testing and data processing facilities was designed and produced byCSR Sifang Locomotive & Rolling Stock Co, Ltd (Sifang Locomotive), a CSR subsidiary based inthe coastal city of Qingdao in eastern Shandong province.

Ding Sansan, the company's chief technician, said the concept of the the super-speed train designwas inspired by China's ancient sword. The bodywork uses plastic materials reinforced with carbonfiber.

Shen Zhiyun, a locomotive expert and academician with both the Chinese academies of sciencesand engineering, said the testing of the super-speed train with speeds of up to 500 km per hour willprovide useful reference for current high-speed railway operations.

You should say on Earth because we have gravity that tense to drop you from going anywhere fast.

Take Bugatti with 1001 horsepower top out at 250mph while  205mph 2012 Chevrolet Corvette ZR1 can reach that speed with only 638 hp. If speed and power were linear the Bugatti should able to do 300mph+.
