[Spring Festival travel rush is in progress]

"You can't make any mistakes when you look at your eyes, fingers, and mouths, and you can't miss a single step." At 2:07 a.m., the signal building of Dacheng Station in Chenyang, Liaoning was brightly lit. The station duty officer Wang Xinran sat in front of the dispatching table, staring at the screen with her eyes intently monitoring the passing of the Z203 train from the lower line. The train automatically triggered through the route. She quickly stretched her arm and pointed at the screen to confirm that the signal was correct. She had to repeat such operations hundreds of times overnight.

Station duty officer, this position is the center of coordination and linkage between various railway occupations and the "strongest brain" to direct the operation of trains. The smooth passage of a train requires close cooperation through seven or eight operational links. During this period, the duty officer must not only conduct vehicle-to-machine control with the locomotive driver and shunt crew to ensure that the information is unimpeded, but also communicate the operation situation with personnel and units such as freight centers, enterprises and other parties to ensure that every detail is foolproof.

The small driving command room, 5 operating tables, 6 telephones, and 34 computer displays constitute all the content of Wang Xinran's daily work. The phone ringing sounds came one after another, and the sounds of communication and communication and up and down were endless, and there was almost no time to spare. The duty officer always maintains a high degree of concentration and calmness to protect the safe operation of the train.

"The preparations are complete and well sealed, 9 locomotives are adjusted, and the shift is planned to open 2 trains at 2 trains..." At 8:30 in the morning, with the end of the night shift, Wang Xinran and his colleague Xu Zitong, who worked in the day shift, carefully handed over the work priorities to ensure that every detail was not missed.

"The trains are not stopped, but our work is not stopped for a moment." As soon as Xu Zitong arrived at the post, he quickly and skillfully picked up the phone and conducted joint control with the driver, confirming that the K4452 train had left the station. Every time she connects to control, she must know every line and every switch on the display screen to ensure that every train operation and every batch of operation plan is accurate.

Dacheng Station is located on the main line of the Beijing-Harbin hub. It not only carries out the marshalling and dismantling of trains in multiple directions, but also undertakes the transportation tasks of 10 enterprise-specific lines including Guoneng Liaoning Thermal Power Co., Ltd. During the Spring Festival travel rush, the number of tasks here is nearly twice as high as usual, with an average of 118 unloading vehicles per day, 335 high-speed trains and 105 ordinary-speed trains. Under such pressure, the duty officer can't be careless for a second.

"The signal of shunting at the power plant is ready." At 11:20, Xu Zitong was watching the shunting team enter the power plant to deliver the vehicle. She just brought the lunch from the cafeteria, and she just took a few bites and put it aside. It was not until 30 minutes later that the batch of homework was over that she picked up the lunch box again and ate a few bites in a hurry. "Apart from the equipment and phone, there is only a water cup around you. When you are at the busiest time, sometimes you don't even have to drink water." At 18 o'clock, it was already dark. The colleague who took over has arrived at the post, Xu Zitong breathed a sigh of relief and slowly got up and left the dispatching desk.

The train passed by and roared, and dense signals came one after another. In this small driving command room, the four "post-00s" Xu Zitong, Wang Xinran, Li Yueru and Li Xiang, commanded the Mercedes-Benz's steel army to pass in an orderly manner. "Although I'm very nervous and tired, I feel it's worth watching every train depart and arrive accurately and safely!" Xu Zitong said proudly after a day of busyness.
