[0027] As described in the background, the virtual marshalling system is based on the CTCS-N system, and adds the functions of station mobile block, train ATO (Automatic Train Operation), virtual marshalling and unmarshalling. The virtual marshalling function can flexibly logically marshal various lengths of freight cars into a train, which can greatly improve the efficiency of freight transportation compared with the traditional mechanical coupling marshalling. The train virtual marshalling scene includes section virtual marshalling and station virtual marshalling. The train virtual marshalling scene includes section virtual marshalling and station virtual marshalling. The section virtual marshalling is divided into manual driving and automatic driving two forms of virtual marshalling, and both of them need the correct cooperation of the vehicle-mounted and ground equipment of the virtual marshalling system to complete a series of comprehensive tasks such as route opening, train departure, marshalling execution and marshalling state reporting.

[0028] The embodiment provides a section marshalling function test method for a virtual marshalling system, to verify the correctness of the section marshalling function. The test method is divided into two scenes according to the departure of the train to be marshalled from the station FS (Full Supervision) mode and the ATO (Automatic Train Operation) mode.
