In the integrated transport system in the west, the railway dominates in long-distance transport. Speeding up the development of the western railway plays a key role in the implementation of the strategy of developing the west. Therefore, the Ministry of Railways decided to speed up the reconstruction of the old lines of the railway in western China and at the same time open new railway lines. In view of the geographical features of the western region, it actively expanded the outreach channel and encrypted the western road network to ease the pressure on the railways entering and leaving the northwestern region. Since then, the western railway investment will account for 40% of the total investment in the country. On the basis of actively improving the existing routes, it will run through the Yangtze River channel and open up the routes of Baotou ~ Liuzhou, Neijiang ~ Kunming, Shanghai
