［Objective］ The operation of virtual marshaling trains (abbreviated as V-train) in urban rail transit meets the construction requirements for green energy conservation and green intelligence integrated development projects. In order to solve tracking interval control problems of V-train operation, the main factors affecting the virtual marshaling interval distance control should be determined. ［Method］ Aiming at the V-train operation control technology, a tracking relative speed protection model for V-train is established based on its interval protection principle and signal system scheme. The influencing factors of interval distance control are analyzed through calculation parameters. The technical characteristics and engineering application advantages of virtual marshaling are also summarized. ［Result & Conclusion］ Main factors affecting the tracking distance between the front and rear V-train are the action response time of the control equipment on the tracking train and the train running speed. V-train application values such as short tracking distance, high train running efficiency and flexible transportation organization are exhibited.
