Abstract：This paper mainly studies how to realize the dynamic management and eficient transmission of passenger information system marshaling through flexible marshalling reconstruction technology. With the rapid development of rail transit，the flexible adjustment of train marshalling has become a key factor to improveoperational eficiency and passenger service quality. This paper introduces firstly the importance and basic functions of passenger information system in modern rail transit，the functional requirements of automatic marshalling reconstruction technology of passenger information system，and the three schemes of adaptive automatic reconstruction technology of passenger information system and their principle and architecture respectively，it discussestheprinciple andmethodof flexible marshallingreconstruction technology，including the modular design of hardware architecture，the configurabilityof software system and the standardization of data communication protocol；secondly，this paper proposes the application of ETBN switch in flexible marshallng train，analyzes the key technologies of ETBN switch in passenger information system application，and compares and analyzes the advantages and disadvantages of ETBN switch networking and ordinary switch networking schemes；finally，it analyzes the key technologiesand studies the typical application schemes.This research provides new ideas and technical support for the optimization and upgrading of rail transit passenger information systems.
