The embodiment of the present invention discloses a method and system for simulating a trackside device of an interconnected crossover line. Information interaction is performed between a host trackside simulator of a host line and a target trackside simulator of a target line. In a process that a train crosses from the host line to the target line, before the head of the train crosses a demarcation point, the host trackside simulator transmits the first message information of a target transponder from the target trackside simulator to an onboard controller, in order that the onboard controller can determine, based on the first message information, the line information whether the target line currently allows the train to enter before the train crosses the demarcation point. The onboard controller controls the train to cross the demarcation point and enter the target line to ensure safe driving only when the first message information allows the train to enter the target line. The method, by means of the information interaction between the trackside simulators of different lines, can obtain the condition of the line to be entered in advance during a train crossing process, and ensures the driving safety of the train.
