China now has more than 30, 000 kilometers of high speed track, and this is expected to increase to 38,000 kilometers by 2025. Fully two thirds of the world's high speed rail（by length）is in China. Here, we track the exciting technological developments in high speed rail and consider their cultural influence.
While the main advantage of the high speed rail lines is convenience for people to get from one city to another as quickly as possible, some of these high speed lines have become popular tourist attractions（places that many tourists visit）. A good example of this is the Hefei-Fuzhou high speed line. Technically speaking, this was one of the most challenging high speed rail routes ever built; nearly 90% of the track was laid either on bridges or in tunnels（隧道）. However, the amazing views are worth it, as the train goes through some of China's most beautiful mountainous areas, including the Huangshan and the Wuyi Mountain Ranges.
As China has gained skills and knowledge in high speed rail, it is trying to export（出口）its technology to other countries. Its first project on the international market was the line connecting Istanbul with Turkey's capital, Ankara, 530 kilometers away. This was followed by projects among other countries. Perhaps its most challenging project is a Trans Asian network（横贯亚洲铁路网）connecting China with Europe. Although it is difficult, China will make every effort to take on this plan. It is hoped to be completed by 2030 as a part of China's Belt and Road Initiative（一带一路的倡议）.
Thanks to high speed rail, the travel time between main cities in China has already been reduced to only a few hours. So this convenience should improve the development within and out of China. No doubt, it will also bring the people of the country closer together, and in time bring about deep social changes.
