The station types are divided into an overtaking station and a non-overtaking station, wherein the overtaking station refers to a station which is only parked by a slow vehicle for passenger taking and landing operation and passes through the fast vehicle without stopping; the non-crossing station refers to a station where both fast cars and slow cars stop for passenger taking and landing operation.
Further, step S202 specifically includes:
step S2021, if the front station is a non-passing station:
and before the large marshalling train enters the station, the train dispatching command system judges the type of the front station, and if the front station is an overtaking station, the train dispatching command system sends a virtual decommissioning instruction to the front train and/or the rear train of the virtual marshalling in the first section. The large marshalling train in the virtual reconnection state is divided into two small marshalling trains of a front train and a rear train, and the two small marshalling trains respectively enter the crossing station;
judging whether the front vehicle and the rear vehicle are fast vehicles or slow vehicles respectively, if the front vehicle is slow vehicle and the rear vehicle is fast vehicle, then: the front vehicle enters a lateral line to carry out passenger taking and landing operation; the back train directly passes through the station from the main line and enters a second interval, a subway operation dispatching commander obtains running real-time state information of the back train and a front slow train running in the second interval through an intelligent train monitoring system, the train dispatching commander sends a virtual coupling running instruction to the back train to be virtually marshalled and/or the front slow train running in the second interval, a running control module of the back train receiving the virtual coupling running instruction and the front slow train running in the second interval carries out train-to-train communication through a wireless communication technology, running speed and spacing distance of the trains are determined by mutual negotiation, a virtual coupling mode is entered, and a new virtual double-coupling large marshalling train is formed to continuously run.
The front train enters a second interval after finishing the passenger boarding and alighting operation and keeps a safe distance from a new large marshalling train in front to operate.
If the front vehicle is a fast vehicle and the rear vehicle is a slow vehicle, then:
the rear vehicle enters a lateral line to carry out passenger taking and landing operation; the front train directly passes through the station from the main line and enters a second interval, a subway operation dispatching commander obtains running real-time state information of the front train and a front slow train running in the second interval through an intelligent train monitoring system, the train dispatching commander sends a virtual coupling running instruction to the front train to be virtually marshalled and/or the front slow train running in the second interval, a running control module of the front train receiving the virtual coupling running instruction and the front slow train running in the second interval carries out train-to-train communication through a wireless communication technology, the running speed and the spacing distance of the trains are determined by mutual negotiation, a virtual coupling mode is entered, and a new virtual reconnection large marshalling train is formed to continuously run.
The rear train enters a second interval after finishing the passenger boarding and alighting operation and keeps a safe distance from a new large marshalling train in front to operate.
Step S2022, if the front station is a non-passing station:
before the large marshalling train enters the station, the train dispatching command system judges the type of a front station, if the front station is a non-overtaking station, the front train and the rear train which are in the virtual reconnection state in the first section do not release the virtual reconnection state, the train enters the non-overtaking station in the form of the large marshalling train, and the front train and the rear train enter a main line to stop for passenger taking and landing operation;
and after the front train and the rear train finish the boarding and alighting operation, the large marshalling train in the virtual reconnection state and the front train in the second interval keep running at a safe distance.

When the virtual reconnection train consisting of the slow train and the fast train is about to enter a station, namely in the end running state of a first interval, virtual decompiling is carried out to obtain two rows of small marshalling trains (the fast train and the slow train), the front train (the slow train) enters a lateral line and stops stably, and the passengers take on and off; the rear vehicle (express) directly enters a second interval to run through the positive line without stopping.
After the rear train (fast train) enters the second interval to run, the rear train is virtually linked with the slow train running in the second interval in front through a virtual marshalling technology to form a new virtual double-heading big marshalling train to continue running.

And after the passenger taking and landing operation is finished, the passenger still enters a second interval to operate in a virtual reconnection state.
When the slow car and the fast car stop at the same platform in a virtual reconnection state, passengers who intentionally take the fast car to go on the journey in the slow car can be organized to transfer to the fast car through the platform, and the transfer at the same platform is completed.

before the large marshalling train enters the station, the train dispatching command system judges the type of a front station, if the front station is a non-overtaking station, the front train and the rear train which are in the virtual reconnection state in the first section do not release the virtual reconnection state, the train enters the non-overtaking station in the form of the large marshalling train, and the front train and the rear train enter a main line to stop for passenger taking and landing operation;
and after the front train and the rear train finish the boarding and alighting operation, the large marshalling train in the virtual reconnection state and the front train in the second interval keep running at a safe distance.
5. The method of claim 4, further comprising:
the slow cars and the fast cars stop at the same platform in a virtual reconnection state, and passengers who intentionally ride the fast cars to go on travel in the slow cars are organized to transfer to the fast cars through the platform to finish the transfer at the same platform when carrying out passenger taking and descending operations.
