With the high speed railway entering the era of “ultra-large-scale network” operation, newly-built high speed railway stations and electric multiple unit (EMU) depots are expanding in scale. This brings pressing challenges regarding the configuration of EMU running lines and their coordination with the station and depots, as well as the calculation of carrying capability after integration of the stations and depots. By analyzing the current research and utilization of carrying capacity of EMU running lines and clarifying the operation workflow after integration of the stations and depots, this paper proposed the concept of carrying capacity after integration of stations and depots and established a simulation model for calculating this capacity under a typical station and depot configuration. Furthermore, a simulation system for carrying capability after integration of stations and depots was developed, which accurately described the interconnections and constraints among station facilities, EMU depots, and EMU running lines. Case studies demonstrate that through simulation analysis of the carrying capability after integration of stations and depots under given EMU running line configurations, it is possible to comprehensively quantify the carrying capacity of EMU running lines, optimize their configuration, and ultimately maximize the utilization efficiency of railway infrastructure.
