With construction of the Qinghai-Tibet Railway, all provinces and autonomous regions in China will become accessible by rail. China's railway network comprises several trunk railroads running east-west and south-north, many feeder lines and local railroads. China has more than 10 railways connected with railways in Russia, the DPRK and Viet Nam. After 1997, China managed to quicken the running speed of trains (five times) by an average of 25 percent. Among transport modes, railway transportation takes first place in terms of passenger and goods transport.
