As the saying goes, “height changes view; angle changes concept and scale grasps life”. While “speed” determines transportation, “transport capacity” changes the transport modes and the “technology” ensures the traffic safety. High-speed rail (HSR) is regarded as a vehicle that changes human life and characterized by “There is not a fastest vehicle,but only faster vehicle”. Compared with other transport modes, HSR has many advantages such as big transportation capacity, fast operation speed, high safety, high punctuality rate, low energy consumption, less influence of environment, land conservation, considerable economic and social benefits.
