I. Railway transportation
Railway transportation is the main force of transportation in China. China railway freight turnover has been accounting for 70% of the total freight turnover in China for many years. Among all kinds of transportation modes, railway transportation takes the first place in passenger and cargo turnover, which is a veritable traffic artery and the main force of China's comprehensive transportation network.
1875, Wusong line, the first railway in China, was completed, with a length of 15km. It was dismantled after only running 16 months. The construction of 188 1 Tang (Mountain)-Xu (Gezhuang) line is the official start of China Railway. In the following 68 years, 25,000 kilometers of railways were built successively, but by 1949, only 2 10000 kilometers remained (excluding Taiwan Province Province).
After the founding of New China, the railway industry in China has made great progress. The mileage of railway traffic is increasing, and the technical equipment is constantly improving. By the end of 1999, the operating mileage of the railway reached 57,900 kilometers, the double-track mileage was 20,900 kilometers, accounting for 36 1%, and the electrified mileage was 1400 kilometers, accounting for 24.2%. With the opening of Daqin heavy-haul railway and Guangzhou-Shenzhen quasi-high-speed railway and the construction of Fuzhou-Xiamen high-speed railway, the construction of heavy-haul railway and high-speed railway in China has begun.

(2) Major railway hubs
Railway hub refers to a transportation and production complex which is located at the intersection of two or more railway lines and consists of several stations, lines and a series of equipment. The task of the railway hub is to handle the disintegration, grouping and line change of a large number of passenger and freight trains between lines. The railway network consists of many railway hubs and different railway lines. There are many railway hubs in China. Important railway hubs include Beijing, Zhengzhou, Tianjin, Guangzhou, Zhuzhou, Wuhan, Shanghai, Xuzhou, Shijiazhuang, Harbin, Shenyang, Guiyang, Chongqing, Kunming, Chengdu, Liuzhou, Xi, Urumqi, Lanzhou and Hohhot.

Second, road transport.
Highway transportation is a door-to-door mode of transportation, with less investment, small volume, high energy consumption, high speed, high freight rate and strong flexibility. It is generally used for short-distance transportation and auxiliary transportation of railways and waterways, but in remote areas, areas lacking railways are transportation trunk lines. In foreign countries, due to the large-scale and high-speed automobiles and the construction of expressways, road transportation has become the main force in the transportation industry.
(1) Main highway trunk lines
There are 12 national trunk lines in China:
1. Tongjiang-Harbin-Changchun-Shenyang-Dalian-Yantai-Qingdao-Lianyungang-Shanghai-Ningbo-Fuzhou-Xiamen-Shenzhen-Zhuhai-Zhanjiang-Haikou-Sanya.

(2) Expressway
Expressway refers to a fully enclosed and interconnected expressway for fast vehicles. The biggest difference between expressway and general highway lies in solving lateral interference and minimizing longitudinal interference. It has the advantages of large traffic capacity, fast driving speed, few traffic accidents and high economic benefits.
China's expressways started late, but developed rapidly. Since 1980s, by the beginning of 2003, the expressway construction has reached 20,000 kilometers. At present, most provinces and regions in China have expressways. The completed expressways mainly include Xibao (Xi 'an-Baoji), Xilin (Xi 'an-Lintong), Xitong (Xi 'an-Tongchuan), Guangshen, Guangzhu, Guangfo, Shenshan and Chengyu. Zheng Luo (Zhengzhou-Luoyang), Beijing-Shanghai (Beijing-Shanghai), Jingjintang (Jingjintang), Shi Jing (Beijing-Shijiazhuang), Shen Jing (Beijing-Shenyang), Shenyang-Dalian, Shen Dan (Shenyang-Nanfen reach), Changsi (Siping-Changchun) and Shanghai. There are three trunk lines in the expressway under construction. One is the Jing-Dan Expressway, with a total length of 850 kilometers, which is part of the world peace expressway plan; The second is the Beijing-Guangzhou Expressway, with a total length of 2,300 kilometers; The third is hanin Expressway, which starts from Harbin, passes through Changchun, Shenyang, Qinhuangdao, Qingdao, Lianyungang, Nanjing and Shanghai to Ningbo, with a total length of more than 3,500 kilometers. It is a big channel connecting Northeast China, North China and East China.

Top Ten Railway Trunks in China
Railway network is a railway network system composed of interconnected railway trunk lines, branch lines, tie lines and railway hubs. At present, China has formed a railway network skeleton with Beijing as the center and provincial capital cities as the center, connecting many railway hubs of different sizes, and the hubs have become the main trunk lines of China's railway network skeleton:
1: north-south transportation hub: Beijing-Guangzhou line
From Beijing south to Shijiazhuang, Zhengzhou, Wuhan and Changsha to Guangzhou, the southern gate of the motherland. Along the way, it runs through six provinces and cities, crosses five major river basins, passes through the North China Plain, the Two Lakes Plain and the hilly areas in the south of the Yangtze River, crosses the Nanling Mountains and connects the Pearl River Delta. It is densely populated, rich in products, developed in economy, densely populated in towns and very busy in traffic.
