Subway is a fast, large volume and electric traction rail transit built in the city. Trains run on fully enclosed lines. Lines located in the central urban area are basically located in underground tunnels, and lines outside the central urban area are generally located on viaducts or ground. Some people have a passion for subway tattoos. Today we collected some subway tattoos. I hope these tattoos can give you a deeper understanding of the subway.
Subway is an urban rail transit system (Metro) with exclusive, high-density and high traffic volume covering all kinds of underground and aboveground rights of way in urban areas. In addition to the subway, it also includes elevated railway or railway paved on the road. Therefore, the subway is exclusive to the right of way and has no level crossing, which is also the fundamental sign that the subway is different from the light rail transit system. The earliest subway in the world is the metropolitan subway in London, England. It was built in 1863.
