In the group, the members are young girls with an average age of 25 years old, and they are affectionately known as the "cute girl group".
The work of these "cute girls" is very special, they maintain the train control equipment on the "Hulk" EMU running on the China-Laos Railway Line every night in the Kunming West Inspection Zone of the Kunming South Electric Section of the Kunming Bureau Group Company of China Railway Kunming Bureau Group Company , commonly known as the "Hulk Brain".
Train control on-board equipment is mainly responsible for recording and real-time analysis of EMU operation data, in the operation of the EMU, can be the first time through the display screen in front of the line status to inform the driver in advance, is an important guarantee for the safety of EMU operation.
Because the EMUs on the China-Laos Railway are only returning to the garage at night, when most people are sleeping, it is the busiest time for "cute girls".
With the arrival of the Spring Festival, the "cute girls" need to overhaul a lot more EMUs than usual, and they guard the safety of every China-Laos railway EMUs with their "hard strength".
"Scheduling scheduling, a set of jobs that request a job to get on the bus". At 0:30 on January 20, 2022, in the Kunming EMU, the "cute girls" stood in front of the "Hulk" who had just returned to the garage, preparing to do a comprehensive examination of the "Hulk's brain".
The winter night maintenance depot is cold and windy, but in order to facilitate the operation, the girls dare not wear too many clothes, carrying several kilograms of tool kits, busy shuttling between the "Hulk" and beyond.
"Our work starts with an external inspection of the EMU. The bottom equipment has been in a state of strong vibration during the high-speed operation of the train, and the bolts, straps and other parts will inevitably loosen, and the wind and sand of the journey will also affect the sensitivity of the 'brain' receiving signal, which may lay hidden dangers for driving safety. So our task is not only to ensure that the system is working properly, but also to nip the hidden dangers in the bud. Shu Song Xiaoyu, the youngest of the "Cute Girls", said while carefully using a wire ball to remove foreign objects from the on-board plug-in equipment of the train control car.
Working under the narrow car, bumps and bumps are inevitable. Touching their heads and puffing up a bag, the girls endured the pain and continued to work, because early the next morning, the Hulk was going to leave south again, leaving them with very limited time for maintenance.
After inspecting the outside of the EMU, it is necessary to pay attention to the inside of the system, just like giving the "brain" a fine MRI examination, which is a key part of the maintenance.
"Train control on-board equipment is the core of the safe, stable and high-speed operation of the train, just like the human brain, collecting information at any time and giving accurate instructions." Shu Song Xiaoyu introduced that accurate time is an important guarantee for the punctual operation of the train and the arrival of passengers on time, and their inspection work requires extremely high accuracy of the "brain" time adjustment, and it is necessary to carefully check the parameters.
In order to facilitate the operation of drivers of both countries, the train control on-board equipment of the EMU on the China-Laos Railway has three operating instructions in Chinese, Lao and English, and every time the "brain" is overhauled, the "cute girls" have to switch the language of different functions and repeatedly test.
"Only special business training, including Lao language training, after layers of selection and assessment, can be qualified to overhaul the train control equipment of the EMUs on the China-Laos Railway." Li Yeqing, who only joined the work in 2020, said.
Meticulous implementation of the standard of operation, not sparing any detail. The temperature in the middle of the night was close to zero, but the girls' fair faces were covered with fine beads of sweat.
Overhauling a group of "Hulks" requires more than 30,000 steps of walking back and forth. During the day, some of them had to take on emergency duty and stick to the garage duty room; the next night, as usual, they checked on the "Hulk" driving back from the China-Laos railway line.
"Maintaining the safety of China-Laos railway trains is our youth mission!" The "cute girls" said in unison that this year is the first Spring Festival of the China-Laos Railway, and they must shoulder the heavy responsibility of maintaining and operating the railway well.
