FIG. 1 shows the track development of the site from st. A 1, Art. B 2 and Art. In 3, control zones ZU 4, control zones ZK 5 and the boundaries of the control zones GZK. From the EC posts to the train locomotives that are in the control zone, information is transmitted about the state of the ahead track sections of the haul located in the control zone and the established routes at the ahead stations. Monitoring of the states of the running track sections ZK 5 is carried out by means of rail circuits RC with two two-wire linear circuits [Patent 2732181] from the border of the station to the middle of the track. The information transmitted to the locomotive refers to the track sections that are located in memory 4, i.e. about the track sections in the ZK and the track sections adjacent to the ZK 5 with a length that corresponds to the passing interval. This allows you to confidently drive trains along the entire route. When the train moves through the station and exits to the haul, the locomotive communicates via the radio channel with the EC post of the departure station. When the GZK passes, radio communication with the departure station is interrupted and radio communication with the receiving station is established.

In case of damage to the main means of control of the track sections of the first or second half of the haul, the regulation of train traffic is carried out using backup devices mounted in a capsule that is attached to the XB.

FIG. 2 shows the location of the DC post; posts EC ECA, ECB, ECV; travel boxes; as well as dispatcher communication lines LD, feeding the RC lines, controlling the RC lines (connecting a track receiver).

FIG. 3 shows mobile URH XV and stationary URS. URH and URS allow to regulate the movement of trains on the stretch in case of damage to the main means of control of track sections. To do this, an employee of the signaling and communication distance sets the URH 11 on the XB, located at the border of the departure station with the haul, attaches the capsule to the throat of the XB automatic coupler, another distance employee removes the capsule at the receiving station. Both operations are performed when the train stops. This mode of regulation of the train movement continues until the damage to the main means of control of the track sections is eliminated.

Before installing the capsule into it, by means of the KX 19 keyboard (Fig. 3), enter information about the system number of the train leaving the section (1, 2, 3, 4) and the number of the half of the section (1 or 2). The system number is the serial number of the train sent for the haul. After assigning a number to the fourth train and leaving the half of the first train, the system numbers are assigned to the next group of trains (1, 2, 3, 4). From each train, for its identification, one of four frequencies is transmitted to the EC post, corresponding to the system number.

The PGLH 16 receiver, using the AG 13 antenna, determines the location of the XB and transmits this information to the computer 20, which controls the operation of the GC 18 and, through the PCX 17 and ARX 14, transmits the information to the nearest EC post. At the post of EC RSE 24, with the help of ARS 15, it perceives information, decrypts it with the help of the DSh 25 decoder and transmits it to the EVMS 26, which participates in the regulation of train traffic using the MPTsS 27.
