The revolutionary development of high-speed railroad system in China has brought the railroad transportation into a new era with the passenger dedicated railroad network with the speed as high as over 300 km/h and a smooth and comfort ride. Long distance travel is no longer dominated by aviation and the high-speed railroad provides a much more convenience and cost effective alternative, not only in developing countries but also in developed countries. The high-speed railroad has changed the way people traveling in China and some other parts of the world. At the present, the People’s Republic of China (PRC) has the largest high-speed rail network in the world, with over 7,000 km of existing track. New lines are added annually in order to form the national four north-south corridors and four east-west corridors high-speed railroad network. With large government investment and leadership from the Ministry of Railways (MOR), China is continually improving its existing lines for commercial train network, while also designing the new passenger dedicated lines (PDLs) to provide a major mode of travel for the country’s increasingly mobile population.
