In the early hours of the morning, in the humid air in the south, a "Fuxing" train slowly entered the first- and second-level maintenance depot of Guangzhou South EMU Operation Station, where inspection, testing, repair and maintenance of EMU trains are carried out.
When the Futian-Hong Kong West Kowloon section of the Guangzhou-Shenzhen-Hong Kong Express Rail Link is about to resume operation, the reporter visited the largest bullet train maintenance station in southern China late at night.
According to reports, Guangzhou Railway Group’s Guangzhou EMU section organized EMU “medical examiners” to carry out in-depth inspections and maintenance for the EMU trains that will soon serve as the Guangzhou-Shenzhen-Hong Kong high-speed rail line, and earnestly do a good job in performance debugging and disinfection of EMUs. The Futian to Hong Kong West Kowloon section of the Hong Kong High Speed Rail is fully prepared for the official resumption of operation.

"This Guangzhou-Shenzhen-Hong Kong high-speed rail 'Fuxing' train will undergo a first-level inspection tonight, and it will take two and a half hours for four staff members to complete the work." Zhou Shuai, assistant engineer of the Guangzhou South Railway Station of the Guangzhou Railway Station, introduced The key point is to do a good job in the maintenance of the train running department, internal service facilities and roof.
First of all, two staff members start to check from the running parts on both sides of the train, and each part must be carefully checked.
Another staff member is responsible for checking the service facilities inside the train, including every carriage, every seat, even every hook, the electric tea stove of the dining car, the water outlet, etc.
Because it is directly related to the comfort of passengers, this part of the inspection is very cumbersome, but the staff is meticulous.
Not only is it meticulous, but it is also comprehensive.
Under the tracks, the long trenches have to be walked again. The flashlights in the hands of the staff can not only illuminate, but also have cameras on them, and every place inspected will also be recorded with images.
Every inspection depends on both eyesight and technology.
Wheel sets, traction motors, gearboxes and other components are the focus of inspection. Once a fault is found, the staff will report it to the superior in time, and then a dedicated staff will come to repair it.

"The most important part of the entire bogie is the wheel set. The main thing is to check its tread to see if there are any cuts, burns and other scars on it." Luo Qian, a staff member who is doing maintenance work, said.
He pointed to a part similar to a pneumatic tire under the car body and said: "This is an air spring, which belongs to the connection between the car body and the bogie. We mainly check to make sure it has no cracks and bubbles. Its function is to adjust the car body. body balance."
After the train was powered off, the reporter followed the staff to the top of the train.
Here we focus on checking high-voltage equipment such as pantographs and lightning arresters.
"Now we are carrying out leak detection work. The focus is to check the carbon slide plate and the corresponding air pipeline to see if there is any damage, abnormality, or air leakage, so as to ensure that the pantograph is in good condition." Zhou Shuai said .
According to reports, according to the inspection and maintenance operation standards, the "Fuxing" train will undergo a first-level inspection every time it travels 8,000 kilometers. Under normal circumstances, four people in an operation team need to inspect four standard trains in one night. It takes about four to five kilometers to walk back and forth.
After the train journey reaches 30,000 kilometers, it will undergo more detailed secondary maintenance.
In addition to maintenance, in order to gradually resume operation of the upcoming Guangzhou-Shenzhen-Hong Kong high-speed rail Futian to Hong Kong West Kowloon section, Guangzhou South Railway Station has also carried out relevant trial operation work in advance.
