Railway transportation is a mode of transportation that uses railway trains to transport passengers and goods. It plays an important role in the process of social material production. It is characterized by large transportation volume, high speed, low cost and generally not limited by climatic conditions. It is suitable for long-distance transportation of large and bulky goods. The railway transportation capacity of old China is very weak. There are only 22000 kilometers of Railways in China. Not only is the quantity small, the quality poor, the technical equipment backward and the layout unreasonable, but more than 90% of them are operated or controlled by foreign capital. Over the past 30 years since the founding of new China, the railway transportation industry has developed greatly. The layout has been gradually improved. Except Tibet, all provinces, cities and autonomous regions have access to railways. The technical equipment and management level have also been strengthened and improved, and will be the main force of China's cargo transportation in the future. Although railway transportation has made great progress, it still does not meet the needs of socialist construction for the increase of transportation tasks, and it is still a weak link in the national economy. In the process of national economic adjustment, the state has attached great importance to the development of railway transportation, highway and waterway transportation as a priority and key guarantee.  From April 1, the railway department will lower the railway freight rate, cancel and reduce some freight charges, and is expected to make a profit of about 6 billion yuan to the majority of shippers and enterprises every year.  During the Mid Autumn Festival holiday (September 12-15, 2019), the national railway has sent a total of 48.01 million passengers, an increase of 5.61 million passengers year-on-year, and an average of 12.03 million passengers per day, an increase of 13.2% year-on-year.
