What is the significance of building a railway?

1. Fundamentally speaking, everyone knows the truth that "to get rich, build roads first", but this is only the propaganda slogan for most people to get rich in rural areas. In fact, the education of Chengdu Railway Transportation School is also very concerned about the development of national construction. The development of rural economy not only depends on road construction, but also the prosperity of a country can not be separated from the related needs of rail transit construction. Take the "Belt and Road" conference hosted by China, which caused a sensation in the world some time ago, this is actually a railway construction project. Its successful construction will show China's scientific and technological strength to the world, announce the rapid development of China's economy, and promote international exchanges to some extent. In addition to these, the state attaches importance to railway construction in order to better promote the economic development of remote areas. Like some areas in the northwest, poor traffic will restrict economic development and affect the improvement of people's living standards. It is urgent to improve the railway construction. Moreover, the construction of high-speed rail will also promote the development of economic and cultural exchanges between north and south cities.

2. China Railway Construction: China Railway Construction began in the late Qing Dynasty. After more than a century of construction and development, by the end of 20 16, the total railway mileage of China reached124,000 kilometers, ranking second in the world; Among them, the high-speed railway is 25 thousand kilometers, ranking first in the world. The double-track rate and electrification rate of China railway reached 54.9% and 64.8% respectively. In China, railway is an important national infrastructure and popular means of transportation, and it is in the backbone position in China's comprehensive transportation system. China has a vast territory, a large population and uneven distribution of resources, so the economical and fast railway generally has great advantages and has become a widely used mode of transportation. The speed increase of China Railway several times is an important event that has lasted for many years since the founding of the People's Republic of China. In the era of high-speed rail, the railway grades in China are divided into high-speed rail, national railway I (including express rail and trunk railway), II III and subway I II. China railway trains are divided into ordinary train, express train series, high-speed train (CRH) and China Standard EMU (CR) series. These concepts have narrow sense and broad sense, but they do not correspond to the third-class railway.
