Two Chinese trains dashing at 420kmh in opposite directions passed each other on parallel tracks yesterday, in the latest feat achieved by China in high-speed rail. At about 11.20am, the two trains, "Golden Phoenix" and "Dolphin Blue", crossed on lines between Zhengzhou in the central Henan province and Xuzhou in the eastern Jiangsu province. The China-standard bullet trains, officially known as electric multiple unit trains, are the first in the world to cross at such a high speed, said national rail service operator China Railway Corporation's technological management department head Zhou Li.
