"Train No. 23 has been parked. A 15-meter short control cable is laid out in room I, and a 25-meter long control cable is laid out in room II. When the cable trough is perforated and tied, the appearance should be straight, neat, and beautiful." At 9:00 on February 1 On the left and right, in the Guangzhou Locomotive Maintenance Warehouse of the Guangzhou Railway Group, Lin Ruitao, wearing yellow work clothes and protective gloves, was concentrating on repairing the diesel locomotive communication radio station.
Lin Ruitao is the foreman of the communication vehicle maintenance area of the Guangzhou Wireless Maintenance Workshop of the Guangzhou Communication Section of Guangzhou Railway Group. After 44 years in the industry, he still communicates the precautions for the day's work before starting work every day. He knew that the co-workers were already familiar with the repetitive content, but he knew very well that every small detail of the communication station was of great importance to the safety of train operation, so he could not afford to be careless.

The communication vehicle-mounted maintenance work area is responsible for the maintenance and repair of 500 miniaturized and standard communication radios for ordinary speed and "Green Giant" Fuxing locomotives, 500 built-in and external 800M communication radios, and 60 rail car radios. The task of the work area is to "prescribe the right medicine" to ensure the safe operation of the locomotive when a "disease" occurs in the equipment.
Lin Ruitao needs to inspect every aspect of equipment installation and use: from the cab, machine room, to the roof, as small as screws and modules, as large as the main unit, antenna feeder, etc., no one can be ignored.

The height from the bottom of the car to the roof is almost 5 meters. Due to the heavy snowfall in Hunan a while ago, in order to prevent the antenna performance from being affected, Lin Ruitao and his co-workers fastened their seat belts, put on their helmets, and slowly climbed onto the roof of the car with a socket wrench. Check carefully whether the multi-band antenna is damaged or falling off.
The workers in the car also carried tools and performed their duties. Some lifted the floor, some installed the host machine weighing dozens of kilograms, and some straightened the cables one by one and tied them to the iron frame. For a moment, iron components emanated from the car. Noise and pungent smell of metal dust.
Lin Ruitao skillfully wrote down the MMI (operation display terminal), speakers, and printing equipment that were replaced on the day in his notebook... To perform such maintenance procedures, they had to climb up and down different types of locomotives several times a day.
"The light inside the diesel locomotive is not good, so during the day, we have to rely on flashlights to illuminate the work. Sometimes we have to bend down to install a cable. Not to mention the old masters, even young people can't stand up after leaning down for a long time." I have sore waist and backache. I work with tools all morning, which consumes a lot of energy and energy." Lin Ruitao said that in the wet and cold winter, his face is covered with sweat, his hands are covered with engine oil, and his body is covered with metal dust. Sometimes his cheeks are stained My face is covered in oil spots, so it’s common to change into three or five pieces of work clothes a week.
"Every time you see the sunshine outside the train window, it means that you have once again worked hard to protect the safety and smoothness of the railway." Lin Ruitao said with a smile.

The entire maintenance process took about two and a half hours. At around 11 o'clock, the voice of the maintenance staff coming from the intercom came to start the machine. "Stop the operation first, and then perform maintenance after starting up." Lin Ruitao said that when the locomotive is started, operations are strictly prohibited according to the requirements, and the work can only be done when the locomotive is stopped. Workers joked that they were "playing hide and seek" with the equipment.
Locomotive communication radio stations are closely related to train driving safety, and the maintenance quality of communication workers is related to the smooth flow of transportation arteries. On the way back, at 11:30, Lin Ruitao discovered that the MMI buttons of several cars were worn. Without upgrading the data in January, he recorded in detail the equipment that needed to be corrected.
Based on many years of experience, he summarized the six-character working method of "asking, watching, listening, testing, analyzing and trying". That is to ask and watch whether the operators use the radio in a standardized manner; use instrument testing and listen to the sound to determine the "cause"; analyze, compare and review the data of multiple stations from the same manufacturer to find out the type of "disease" on site, and formulate rectification according to the actual situation; function test to ensure that it is repeated again Used normally.
After decades of hard work, this year is Lin Ruitao’s last Spring Festival travel period at the post. Standing at every post well and fulfilling every responsibility is his practice and persistence of his original intention. (over)
