China’s High Speed Railway “High speed rail travel” has been called the most revolutionary means of transport of the late 20th century and early 21st century. Today, China’s high-speed railway or CRH, is the best example of such “revolutionary means of transport”. In fact, CRH only began to develop in early 2004, when China issued its “Mid and Long-term Railway Network Plan”, the first such development in China’s history. It was in little more than six years that China’s railway realized its leap-forward, which made it possible for China to head into “an era of high-speed railway”. On September 28, 2010, for instance, China‘s homemade “Harmony - CRH380A”, a new generation of experimental high-speed train, realized the high speed of 416.6 km an hour along the track from Shanghai to Hangzhou. This is the world’s highest speed in the history of railway. China’s high speed railway is now at the forefront of the world‘s high-speed railway, and has become a model of “China Speed” and “Made in China”. According to China’s railway network development plan, by 2020, China’s total mileage of railway will have almost doubled, exceeding 120 thousand kilometers, of which high-speed railway will account for over 16 thousand km. By then, a grid network of China railway with four horizontal and four vertical tracks will be formed, including the Beijing-Shanghai high-speed rail line, and the Beijing-Shenzhen-Hong Kong high-speed rail line. At that time, the travel time from Beijing to Shanghai will be shortened from 10 hours to less than hours. The travel time from Beijing to Guangzhou will drop from 22 hours to only 6 and a half hours. From Beijing to Kunming, the travel time will also be changed from the current fastest travel time of 38 hours into no more than 8 hours. Even from the Beijing to the distant city of Urumqi, the travel time will also be reduced from 40 hours to just 11 hours. As the American publication “Newsweek” put it: China is now engaged in a “railway revolution”. These 350 kilometers per hour high-speed railway trains have made the country’s vast territory "substantially smaller”, and changed the country economically.
