The high-speed rail, the high-speed railway, was quickly developed in Japan and the United States after the opening of the first high-speed railway, Japan's Shinkansen system.

The current high-speed railways in China include the Beijing-Tianjin Intercity, the Changjiu Intercity, the Shijiazhuang-Taiyuan Passenger Line, the Changji Intercity Railway, the Jiaoji Passenger Dedicated Line, the Shanghai-Nanjing High Speed ​​Rail, the Wuhan-Guangzhou Passenger Line, the Zhengzhou High-speed Railway, and the Wenfu Line. Hanyi Line, Beijing-Shanghai Line, Fuxia-Xiamen Railway, Chengguan High Speed ​​Rail, Shanghai-Hangzhou High-speed Rail, Shanghai-Nanjing Intercity Railway, Guangzhu Intercity Railway, Hainan East Central Railway, etc. The Beijing-Shanghai high-speed rail is also expected to formally run on June 28th. At present, some reporters have experienced the feeling of taking the Beijing-Shanghai high-speed rail. It takes less than 8 hours to travel from Nanjing to Beijing. The Nanjing South Railway Station high-speed rail schedule has also been established. There are 71 pairs of train trains planned each day. At the same time, with the opening of the Beijing-Shanghai high-speed rail, passenger flow is reduced. Nanjing Hanzhongmen Bus Terminal, Zhonghuamen Bus Terminal, and Shimonoseki Bus Terminal. The four passenger stations at the Maqun Bus Terminal will be officially closed.

The completion of the Beijing-Shanghai high-speed rail will not only ease the pressure on passengers and cars, but will also promote the development of the tourism industry in the surrounding cities along the route and drive the business district. The tourism attractions along the high-speed rail line are relatively rich, so the theme of “peer, sharing, and mutual benefit” is the theme. The seven cities of Beijing, Shanghai, Tianjin, Nanjing, Jinan, Ganzhou and Fujian also form a tourism alliance. At the same time, the high-speed rail can also increase the number of passengers who choose high-speed rail to make a self-guided tour in Nanjing, and vigorously promote the progress and development of tourism in Nanjing.

In addition, as the fares of the Beijing-Shanghai high-speed rail are relatively high, the most expensive one reaches 1,750 yuan, and the price of the Beijing-Shanghai route has dropped somewhat, which is not much different from that of the high-speed rail, and even lower than that of the high-speed rail. The results of high-speed train trial operation show that the signal in the high-speed rail is also relatively poor, so the high-speed rail currently appears to have less advantage than flying. Therefore, in order to cater to the market and attract passengers, the relevant high-speed rail company will cut down the fare appropriately and reduce the margin. At around 5%, this will likely make some travelers back for the Shanghai-Nanjing high-speed rail.
