The dispatching office of China Railway Nanning Bureau Group Co., Ltd. is the command center of Nanning railway system
The Nanning hub is responsible for the dispatch of all trains at Nanning Station, Nanning East Railway Station and Nanning EMU, and the dispatchers are working seriously
On the desk surface of the dispatch office, each dispatcher has a certificate next to him, and the certificate is bright
"Pull a hair and move the whole body", which is a true portrayal of the railway dispatching office. As the "strongest brain" of the railway system, every instruction issued here is related to the safety and order of passenger and freight transportation. When do trains depart and when do they arrive? How are these instructions issued? On the evening of January 21, the reporter came to the dispatching office of China Railway Nanning Bureau Group Co., Ltd. (hereinafter referred to as Nanning Bureau Group Company) to visit this place, which is known as the "railway nerve center".

Each dispatcher is staring at at least 8 computer screens
At 9 p.m. on the 21st, the reporter walked into the dispatching office of the Nanning Bureau Group Company. It is the railway transport command center of Nanning Bureau Group Company, responsible for the daily passenger and freight transport scheduling organization, and has jurisdiction over 7 general speed railways such as Xianggui and Jiaoliu lines, as well as 7 high-speed railways such as Liunan Passenger Railway, Guiguang Passenger Railway, Nankun Passenger Railway and Nanguang Line. The railways under its jurisdiction span Guangxi, Guangdong, Hunan and Guizhou, with a mileage of 5,804 kilometers, of which 1,859 kilometers are open to traffic.
There are no railways or trains, and it is more like a circular theater with multiple rows of seats. Dispatchers in dark blue uniforms sit in front of the dispatch desk, staring at computers, phones and pencils, closely monitoring the movement of passenger and freight trains. There is a large screen hanging on the back wall, which displays the status of the Nanning Bureau railway train operation map, station schematic map and basic situation of the line in real time.
There are 76 dispatch stations set up by the dispatching office, each dispatching station is responsible for a railway trunk line under the jurisdiction of the Nanning Bureau, which is composed of at least 8 computer screens. On the display in the middle of the dispatch station is a spider's web of complex and orderly real-time train operation maps. This figure is based on the time horizontal coordinate, the distance is the vertical coordinate, and a polyline represents the direction in which a train runs. Among them, the red line represents the passenger car, the black line represents the freight car, the green line represents the basic operation map, and the dots on the line are the stations through which the train passes. The first job the dispatcher does every day is to carefully examine this "net". On other displays, disaster prevention and early warning systems and station surveillance videos are running.
Train dispatchers are like traffic police on the highway
When will the train depart and when will it arrive? If a train is delayed, subsequent trains will be affected, how to deal with it? These issues may not be clear even to frequent train passengers. In fact, these problems are handled by the dispatch known as the "railway nerve center".
Chen Jiahai is a dispatcher at the Nanning Hub Station of the Dispatching Office of nanning bureau group companies. The Nanning Hub Is responsible for the scheduling of all trains at Nanning Station, Nanning East Railway Station and Nanning EMU. Chen Jiahai said: "We have set the point of the train, but sometimes there are changes. For example, passenger trains on peak lines and additional passenger trains are realized through the daily shift plan, and the delay of the train plan map is the opening of the train. ”
"A train dispatcher is the equivalent of a traffic policeman on a highway. If the train is delayed in a large area, the train operation order is very chaotic, and the stock road is not enough, it is necessary to let which train go first and which train waits in which channel through the careful organization of the dispatcher, so that the train can restore normal order. Chen Jiahai said, "Just like the traffic police on the road when there is a large-scale traffic jam during the rush hour, they also restore normal traffic order through manual or control signals." ”
Take a high-speed rail dispatcher as an example, he has to direct the safe operation of high-speed rail trains every day according to the operation chart, keep an eye on the road, plan to issue and issue dozens of dispatching commands, click the mouse countless times, answer and dial the dispatching phone countless times, deploy, confirm, and issue various operation plans, and at the same time, continuously monitor at least 8 dispatch monitoring monitoring displays in real time...
Every day, as soon as you take up your post, you are on high alert
Every morning at 5:00 a.m., EMU trains begin to run out of the depot. Chen Jiahai is responsible for the Nanning hub dispatching station to receive more than 200 pairs, 400 trains, after the Start of the Spring Festival, with the opening of additional trains, the scheduling work increased. Although passengers do not feel the presence of dispatchers on the train at all, the punctuality and safety of the train are directly related to their operation in the background.
"Ringing bells..." During the interview, the phone from Chen Jiahai's dispatch desk rang. After answering the phone, Chen Jiahai pressed "Deleted" on a train message on the display. "What does it mean to be deleted?" The reporter asked. "After our dispatcher changed the train number, because the station did not have the right to change the train number, we had to help delete it ourselves." Chen Jiahai said.
The dispatch desk here just put down the phone, and the phone at the dispatch desk rang again. Dispatcher Wu Xiaobing talked to the driver of a train at Liuzhou South Railway Station to confirm that the train was running normally.
It may seem to outsiders that the dispatcher sits indoors, looks at the screen, clicks the mouse, and answers the phone, which is a very easy job. As everyone knows, they must analyze and process the train operation data at any time, and communicate closely with the station and train on the weather, line operation, etc.; direct the operation of the train, adjust the plan, issue dispatching orders, and use a set of satellite private network call systems that directly contact the station and the train driver to continuously handle various requests that need to be coordinated...
"As soon as our dispatchers take up their posts, their spirits enter a state of high alert and a super fast operation mode." A dispatcher said.
The wish is to achieve scientific scheduling to achieve train punctuality
The EMU trains do not operate at night and will enter the EMUs for maintenance and rest, but the work of the dispatcher will continue at night. Chen Jiahai's induction time that night was from 19:00 to 7:30 the next day, "some lines of the high-speed rail in the evening need to be overhauled and constructed, so they also need to be dispatched, including the monitoring of train operation."
During the interview, the reporter asked: "As a dispatcher, what is your greatest wish?" Chen Jiahai said: "The biggest wish of the dispatcher is to ensure the safety of passengers at the same time, through careful organization, scientific scheduling to achieve train punctuality." ”
There are 411 dispatching staff members of Nanning Bureau Group Company, with an average age of 38.4 years old, 4 management departments of comprehensive, analytical, safety and technical education, 15 professional dispatching rooms such as high-speed rail, driving and planning, and 4 dispatching teams. Work day and night to be the "nerve center" of the train, escorting passengers to travel safely and the smooth passage of goods.
According to Zhang Hong, the head of the dispatch office, during this year's Spring Festival, the transportation capacity will be supplemented by adding temporary EMUs, adding hangings and expanding the number. In terms of EMUs, a total of 35 pairs of temporary EMUs were arranged, all of which were concentrated on the Guiguang Line; the Pusu Linke side was the same as last year, mainly concentrated in the direction of Xingyi to Hangzhou and Guangzhou, and the trains from Sichuan and Chongqing to Guangzhou. In order to continuously improve the quality of service, the railway department has always taken the improvement of the punctuality rate of passengers as an important starting point for improving the travel experience of passengers, and has improved the system and standardized assessment by strengthening the analysis of bus timing and delay, strictly controlling the delay of passenger car responsibility, and continuously improving the punctuality rate of passenger cars.
