The urban railway refers to a passenger rail transit system in a metropolitan area, which serves cities and suburbs, central cities and satellite cities, key towns and the like, the service range is generally within 50-100 kilometers, the distance between stations is short, the density is high, the design speed is preferably 100-160 kilometers/hour, and the average station spacing is not less than 3 kilometers in principle. Urban rail transit belongs to the category of generalized urban rail transit. The subway is one of urban public transport modes, is usually planned and constructed in a central urban area at home and abroad, has short station distance and high density, the target speed value is generally lower than 100 kilometers per hour, the average travel speed per hour is 25-35 kilometers, and the line length is generally less than 50 kilometers.
The subway and the urban railway have different designed running speeds and different requirements, and the performance of the subway train door and the shielding door in the subway station cannot meet the requirements of fire prevention, explosion resistance and wind pressure resistance and cannot be powered on.
