Among many cities with railways, the first subway with 5G signal network appeared in Beijing, which is Beijing Metro 16 Line. The 1 subway line that goes under the Yellow River is located in Lanzhou, which is the 1 subway line in Lanzhou. In addition, there is the 1 subway cross-sea line, which is located in Xiamen and is the second line of xiamen metro. The first inter-provincial subway line appeared in Shanghai, which is Shanghai Metro Line 1 1, and it goes straight to Jiangsu.
The advantage of subway is to save land, especially in many busy metropolises. Land in urban areas is particularly expensive. If the subway is built underground, it can greatly save space, and the land on the ground can be used for other construction or use. In addition, the subway can also reduce noise, because it is built underground, which greatly reduces the noise on the ground.
