What Is Line Management?

The line is a demarcation point without wiring, and generally only handles the work of receiving and dispatching trains. In the semi-automatic blocking section, in order to divide the section and improve the passing capacity, set up a depot in a relatively large station section, or there are stations to different directions.

The line station generally does not arrive and depart, only to set up a notice and

1. How to drive at the line

(1) The line station shall be equipped with the same basic blocking equipment as the adjacent station (station).

(2) There is a line station through the signal machine, and the train runs close to the line and runs according to the signal displayed by the signal line through the line. The train stops after it stops at the traffic signal passing by the line, and the driver drives by himself according to the signal allowed to run through the traffic signal. When the train is forced to stop in the section and needs to retreat, it is not allowed to pass the traffic signal passing the line without the consent of the watchman on the line.

(3) The traffic signal (outbound traffic signal) passing by the line cannot be opened for some reason. Automatic occlusion interval. With a green permit, the train crossed the line and passed the traffic signal to the next block. Operate according to the signals it displays; the basic blocking method must be stopped between automatic stations or semi-automatic blocking sections, and traffic should be driven by the telephone blocking method.

2. Driving method for unattended lines

8 km line stations, 21 km line stations, 33 km line stations and 44 km line stations will be added between Hetian Line Longtianmyeon to Xin'anyu, Xin'anyu to Mishan, Mishan to Huazhou, Shandiling to Maoming Station. The basic blocking method between the line station and two adjacent stations is automatic station blocking. In this section, axle counting equipment is used to achieve automatic station occlusion, and it does not have the function of checking broken rails.

(1) Driving method under normal conditions of equipment

Confirm the interval idle mode:

aWhen the departure direction is not changed, the departure station must confirm that the interval from the station to the line is empty. The number of axes display is 0000, T ×× G occupied (departure direction) means the light is off, and TxxG is idle (departure direction) The indicator light is on.

b. When changing the direction of departure (departure from the original pick-up station), the original pick-up station must confirm that the section between the station and the line station, the section between the line station and the original station is free (that is, the section between the station and the original station is free) and the original station is not Departures at the line: T ×× G is idle (receiving direction) means the light is on, T ×× G is occupied (receiving direction) means the light is off, the number of axes display is zero, and adjacent station T ×× G is idle means the light is on, Neighboring station Tx × G is occupied means the light is off, and the neighboring station handles the departure when the light is off.

The station must obtain the consent of the train dispatcher before handling the train advance notice.

(2) Driving method under abnormal conditions of equipment

Zero resetting method for axle counting equipment failure: When the interval between the departure station and the line station and between the line station and the pick-up station is free, the number of displays of the number of axes at the departure station (or pick-up station) is not zero. Direction) "or the pick-up station" T ×× G occupancy (receiving direction) "indicates that the lights are on, and the station attendants at both ends of the section report to the train dispatcher. After the three parties jointly confirmed that the interval between the departure station and the pick-up station was vacant, the train dispatcher issued a dispatch order agreeing to use the axle counting reset button to both stations. After receiving the dispatch command at both ends. Break the lead seal of the counter reset button. At the same time, press the counter reset button at this time. At this time, the counter reset at two stations indicates that the lights are flashing, and the lights are off after 13s. The departure station is T ×× G occupied (departure direction) or the station T ×× G occupied (Receiving direction) "means the light is off and the departure station is" T ×× G
"Idle (departure direction)" or the pick-up station "T ×× G idle (departure direction)" indicates that the light is on and the number of axes display is zero.

1. EMU trains need to run in isolation mode in the section. When the front line is a line depot where the two lines meet, the train dispatcher must prepare the passage of the EMU train at the line depot before allowing the driver to change to the isolation mode. .

2. When an EMU train needs to cross the previous signaler of the traffic signal passing by the two lines in the line direction in a visual mode, the train dispatcher must prepare the EMU train at the line station before notifying the driver of permission. Through the road. ^[2]

Provisions governed by temporary lines:

(1) After an accident or disaster occurs in the section, the train dispatcher issues an order according to the instructions of the accident investigation committee or the headquarters to block the section and set up a temporary circuit in the section. The temporary demarcation point to which the temporary line belongs shall be equipped with corresponding driving equipment, and the line watchman, assistant watchman, shunter and protector may be set as required.

(2) The temporary line is subject to the leadership of the accident investigation committee or the headquarters, under the direction of the train dispatcher at the dispatching station, and is responsible for contacting the two ends of the station to handle the temporary line related to the train's receiving and dispatching and the on-site rolling stock. The driving work of the station is directed by the line attendant.

(3) When the line resumes driving, in order to improve the passing capacity, with the company's consent, the temporary line may be retained as a temporary demarcation point, and temporary station landmarks shall be established. Protective points shall be set at no less than 300m at each end to protect with deceleration signals. . ^[3]
