trains from a station equipped with electrical interlocking, and then recited for the case of a train departure from a station equipped with route control devices.

After setting the route, the control relay 18 is activated to open the output traffic light and the relay 19 to memorize the installation of the route route.

Relay 18 is energized through the front contact 4 of the relay of the signal circuits of the output traffic lights and becomes self-blocking along the circuit from the contact 17.2 of the relay 17 restoring the semi-automatic blocking, the front contact 28 of the track relay of the section of the path common to all routes, the own front contact 18.2 and the rear contact 14 relay fixing the arrival of the train.

Relay 19 of storing the route setting is excited through the rear contact 13 of the route disconnection relay (for EC stations this is the rear contact of the closing relay of the track section common to the departure routes), front contact 27 of the track relay of the route section common to all departure routes, front contact 5 of the relay the closure of the signal circuits of the output traffic lights.

At the receiving station, the relay 18 is also excited along the circuit from the front contact 23.1 of the relay 23 forming a signal about opening the output traffic light, the rear contact 1 of the relay forming the signal of departure for the train and the rear contact 14 of the arrival arrival hold relay.

If the train leaves, the relay station 18 is de-energized as a result of the disconnection of the initial excitation circuit by pin 4 and the self-blocking circuit by pin 28. Relay 19 to memorize the setting of the route of departure is also de-energized by deactivating the circuit first by pin 27, and then by pin 13 of the relay after the train went smi cani route.

At the receiving station after the arrival of the train, the relay 18 of the control to open the output traffic light is also de-energized by the rear contact 14 of the relay of the arrival of the train.

If the train’s departure did not take place and the route was canceled or artificially cut, the departure station caused the route to open the trip by the rear contact 13 of this relay to turn off the relay 19 to start sending the route, but the relay 17 is energized during de-energization. restoring the semi-automatic interlocking by the circuit from the front contact 19.1 of the relay 19 of the front contact 12 of the relay of route opening, the front contact 18.1 of the relay 18 and becomes self-locking through own fronto

How to contact 17.1. When energized, the relay 17 by contact 17.2 de-energizes the relay 18 and the front contacts 17.3 and 17.4 sends a pulse of the excitation current of the relay 20 to the receiving station. The circuit passes at the departure station from the power source through the front contacts 17.3, 17.4 relay 17, rear contacts 23.4, 23.5 relay 23, in block 22 of the switching circuit of the blocking signals through the rear contacts 10, 11 of the exit light re-opening relay, through a two-wire linear circuit 24 , connecting the neighboring stations at the receiving station in block 22 through front contacts 10 and 11, front contacts 8 and 9, rear contacts 2 and 3, rear contacts 15, 16 and further through front contacts 23.2, 23.3 relay 23, front contact 18.3 relay 18, winding re Le 20 controls the opening route.

The duration of the current pulse sent from the dispatch station by the front contacts 17.3, 17.4 of relay 17 is determined by the deceleration time to de-energize the control relay 18 to open the output traffic light and the deceleration time to de-energize the relay 17, which is turned off by the front contact 18.1 of the relay 18 and sufficient for excitation at the station receiving the relay 20 of the control for unlocking the route and relay 17 through the circuit through the front stage 20.1 of the relay 20 controlling the distance of the departure route, the front contact 18.1 of the relay 18.

The relay 17 for restoring the semi-automatic interlock at the receiving station becomes energized to self-blocking

through its own front contact 17.1, the rear contact 17.7 turns off one of the power circuits of the relay 23 and the rear contact 17.2 turns off the self-blocking circuit of the control relay 18 to open the output traffic light.

Relay 23 ceases to receive power after the end of the pulse from the sending station as a result of de-energizing the reception station of the relay 20 unlocking the sending route and turning off with its front contact 20.2 of the second power circuit of the relay 23. After de-energizing the relay 23 with the front contact 23.1 it turns off the initial drive circuit of the control relay 18 open the output traffic light, and after closing its rear contacts 23.4, 23.5 sends to the sending station a current pulse coinciding with the polarity of the current of the blocking signal Arrival. The duration of this current pulse sent from the receiving station is determined by the deceleration time of the relay 18 and the deceleration time for the relay 17. The current pulse passes at the receiving station along the circuit: power supply, front terminal 17.3, 17.4 relay 17, rear contacts

Relay 21 on the sending station, excited by the field current coinciding with the current of the 1-blocking signal Arrival brings the whole circuit of the block 22 of the interlocking signal circuits to the initial state.

Thus, devices of relay semi-automatic blocking at both stations are ready to give consent to sending from any station.

When setting the train departure route at a station equipped with a route with 1 control devices and rail circuits, the control 18 control of opening the exit traffic light is energized through front (4 contact 4 of the relay of the signal circuits of the output traffic lights and memory 19 route is excited by a circuit with an implementation option for a given station: the front contact of the closing relay of the signal circuits of the output lights and the front contact of the relay preventing the reopening of the output traffic light the deceleration time for its crust falling off, and becomes self-blocking through its front contact: and the rear contact of the relay to prevent the re-opening of the output traffic light.

When the route is routed, the route unlatching relay is energized via the contact of the button for artificially breaking the route.

Then, the relay 17 for restoring the semi-automatic interlocking by the circuit through the front contact 19.1 of the relay setting memory 19 and the front contact 12 of the trip opening relay is energized. In the future, the operation of the device is similar for the case of cancellation or artificial cutting of marz shipment at the station with electrical centralization.
