Subway, as a form of railway traffic, refers to the urban rail transit system that mainly runs underground, that is, the abbreviation of "subway" or "subway".

Many of these systems will be converted to the ground or elevated roads outside the city center to match the construction environment and consider the construction and operation costs.

From a professional point of view, the difference between light rail and subway is not in the sky and underground, but in its rail weight and maximum cross-section passenger flow: the rail weight is less than 60 kilograms per meter, and the passenger flow per hour is1.5,000 to 30,000 passengers. A subway with a track weight of more than 60 kilograms per meter and an hourly passenger flow of 30,000 to 60,000 passengers is called a subway.
