Abstract Research purposes: In recent years, the construction of suburban railways in major metropolitan areas in China has shown an accelerating trend, and the direction of multi-network integration development is not clear. There are differences in main technical standards, interconnectivity, and operation management, which have brought obstacles and uncertainties to the functionality and benefits of suburban railways after completion and operation. The paper studies the key technologies of suburban railways interconnection and interoperability under the mode of multi-network integration, in order to provide comprehensive technical support for the implementation of suburban railways interconnection and interoperability.
Research conclusions: (1)Vehicles operated through interconnection and interoperability should be compatible and can be achieved through vehicle classification, unified vehicle formations, etc. The gauges should be consistent or inclusive. (2) The infrastructure standards for civil engineering should have compatibility and meet the conditions for offline operation of other rail transit trains. (3)The power supply system, communication system, signal system, and platform door system should have consistency or compatibility, and can also be achieved through different standards of mechanical and electrical equipment, system to system conversion, and other methods. (4) Overall consideration should be given to achieving coordination and unity between suburban railways and other rail transit systems in terms of train operation organization, operation management, ticketing management, and security inspection systems. (5) The research results have certain reference significance for the construction and integrated operation of suburban railways under the multi-network integration of rail transit.
