As can be seen from FIG. 1, the claimed system contains a central operating point 1, an additional underground terminal 2, an emergency terminal 3, a remote ground weather terminal 4, a duty station 5, trains 6, 7. Each train includes a head carriage computer 8 for trains 6 and 9 for trains 7, computers in each car 10 for train 6 and 11 for train 7, displays in each car 12 for train 6 and 13 for train 7.

On the lines are the central operational points 1, which carry out the reception, processing and transmission of signals that carry various information. The number of points 1 on each line may vary; so, for example, there can be one point 1 on each line, maybe two points, and maybe three or more. There may be the following options: the first option, when the same number of points 1 is contained on different lines; the second option, when different lines contain a different number of points 1, for example, one point 1 is on one line, two points 1 are on the other line, three points are on the third line, and one point 1 is on the fourth line.

The number of points 1 depends on the information load of the line and the amount of information processed on it.

The central operational point 1 may be located at one of the metro stations.

The remote ground-based weather data terminal 4 monitors weather conditions on the surface of the earth. From this terminal 4 to the central operational point 1 via an external local network, which can be telephony lines, messages are sent regarding weather conditions on the surface (temperature, precipitation, pressure, etc.). To be able to transmit information over a telephone line, it is necessary that Operation Point 1 contains a modem connected to the telephone line.

At central point 1, the received information is processed, systematized, and then transmitted via internal wired local network to additional underground terminals 2 of all stations located on the line serviced by the mentioned central operational point 1. Additional underground terminal 2 receives information regarding weather data and displays it on a display 14 located at each station. This information can be found by any passenger entering the subway or leaving the subway.

Using this display 12 or 13, the train passenger can determine the shortest route to the desired location.

Such prompt receipt of emergency information in the metro allows the passenger to determine their arrival time at a particular station and, accordingly, adjust their route, for example, get off at another station and transfer to another metro line or another mode of transport.

To adjust his route, the passenger using the display 12 or 13, which can be made in the form of a touch screen, enters his additional data by clicking on the corresponding areas of the touch screen. According to the results of processing the information entered by the passenger and the information received from the emergency terminal, the passenger is displayed on the touch screen relevant information.

At the emergency terminal 3, information about emergency situations comes from the wagons of another train 6 or 7 in which this emergency situation occurred, or from the duty station 5, if an emergency situation occurs at the station. Information in this case from the computers of the wagons 10, 11 of the train 6 or 7 is received at the central operational point 1 via wireless communication (for example, radio communication).

In addition, the central operational point 1 for wireless communication (for example, radio communications) transmits messages of an advertising and informative nature to the computer of the head car of trains 6, 7, where the received messages are transmitted via a wired local bus of the train to computers 10, 11 in the cars, and then to touch displays 12, 13 on which they are visualized.

The computers of the head cars 8, 9 of trains 6, 7 transmit information regarding the waiting time of the train to the additional underground terminal 2 of the station to which they must arrive. An additional underground terminal 2 processes the received messages and displays them on a display 14 located at the station.

The dispatcher of the central operating point, using the keyboard 17, can enter control commands and data on adjusting the train schedule and the work of train drivers. All schedules and work schedules of subway workers are stored on your hard drive. From duty station 5, information can be provided to the emergency terminal via both wired and wireless communications.
