12 SPECIALITIES OF HIGH SPEED RAILWAY NETWORKS IN CHINA AND THE SELECTION OF THEIR TECHNICAL SCHEMES
LI Hong, Yu Qian-feng
Being different from Europe and Japan, the high speed railway network in China consists of the dedicated passenger traffic railway lines after the separation of passenger traffic from freight traffic in the busy trunk railway lines. Due to its smaller operation area, a rapid railway with combined running of passenger and freight trains is required. The operation models of the high speed railway in China are the mixing running of high-speed and medium-speed trains, passenger and freight trains running in the same railway line, and the high-speed trains using the same stations with the common trains. As if the maglev technology will be used for the Jing-Hu high speed railway, the vast resources of existing railway cannot be utilized. Not only the investment will increase, but also will give passengers extremely inconvenience.
