Abstract: The technologies for dynamic optimization function of metro fleet composition include physical coupling/decoupling technologies and virtual coupling/decoupling technologies. This paper focuses on the study on physical coupling/decoupling technologies, providing a relevant signaling system solution. Based on the analysis of the operation requirements, this paper presents the target of physical coupling and decoupling functions, and introduces the coupling and decoupling processes. Meanwhile, it also discusses the methods for realizing such key technologies as coupling speed control, train interface, location report transmission mechanism, and the switchover of the leading end of a newly coupled train, taking into consideration the CBTC features for interoperability.

Key words: flexible marshalling, train coupling, decoupling, urban rail transit, signaling
