In recent years, with the rapid development of China's transportation technology, high-speed railway has become the label of "made in China" in the new era.China has a vast country with uneven distribution of economy and resources. Where high-speed railway goes, it plays a role of promoting and balancing the economy along the line, speeding up the process of urbanization, driving the investment and development of underdeveloped areas, promoting the formation of traffic economic belt and the rise of high-speed railway new towns.Now, after more than ten years of development and construction, the operating mileage of China's high-speed railway has reached 25,000 kilometers, accounting for two-thirds of the world. It is self-evident that China vigorously develops high-speed railway.
