CHONGQING (CQNEWS) -- When night falls, lights of Chongqingxi Bullet Train Maintenance Station, 10 kilometers away from Chongqingxi Railway Station are bright. Trains running across the country in daytime are stably parked in the workshop, waiting for the “doctor” to check their “body”. Just like the hospital departments, the maintenance staff of bullet train are divided into dispatching, quality inspection, on-site technology, cleaning and other types of work. Every night, nearly 200 “dotors” stick to their work here. With the arrival of Spring Festival travel rush, in order to deliver every passenger safely to the destination, “Doctor Bullet Train” need to handle heavier and complex maintenance work.

At 19:00, trains come back to the maintenance station one after another, “Come on, and wash your face first.” In order to make this “China Name Card” brighter, sweepers are cleaning the “head” of the train carefully. During the Spring Festival travel rush, the railway line will be busy, and the maintenance workload will be increased from an average of 19 groups to 24 groups every day, and 30 people will be on duty every night.

“There is no operation in Lane 2, so please go to Lane 2 as planned, and power off when pantograph lowering is in place...” Just after the voice fell, two motor train mechanics climbed onto the roof and carried out the pantograph inspection meticulously. The train will lose power without gasoline, and the pantograph installed on the top of the train is an important electrical equipment to obtain electric energy from the catenary, and is the “lifeline” of the train.

In the TDES Image Analysis Center of Chongqingxi Railway Station in Chongqing depot, more than 10 staff are staring at the image on the screen. This is the picture taken during the driving process of the bullet train. Before the maintenance, they need to pass through their “eyes”. It's a common practice for them to look at tens of thousands of pictures all day.

Tang Haoming, 23, was in No. 4 position of the first maintenance shift. “It takes more than two hours to repair a set of motor trains, and many trips back and forth from the front to the back.” During the Spring Festival travel rush, on average, the motor train mechanics need to repair three sets of trains every night, and walk more than 30,000 steps in the repair shop one night.

The flashlight of the motor train mechanic is not simple. In addition to the lighting function, it is also equipped with a camera. In order to ensure that no inspection link is missed, the flashlight will record every detail of the maintenance, just like a “tachograph”.

The “doctors” need to work continuously from 6 p.m. to 8 a.m. the next day. Generally, their work was divided into four positions. No. 1 and No. 2 were mainly responsible for the inspection of the cab and roof equipment of the motor train, and No. 3 and No. 4 were mainly responsible for the inspection of the side and under the train.

Two bullet train mechanics are measuring the height and thickness of the wheel rim with the “four inspectors” that can be accurate to 0.1 mm. High-speed train running, safety is crucial, maintenance work must be improved.

In order to ensure the safety of every trip, “doctors” need to walk more than ten kilometers on the roof, under the chassis and in the gutter all night, overhaul dozens of bogies, and confirm whether tens of thousands of parts were in good condition.

During the day, you sit on the comfortable seat of the motor train and look out the window. At night, the staff laid on the ground and carefully checked each screw on the seat to make sure it was not loose.

Bullet trains are mainly in white tone, so it’s hard to avoid “dust collection” when travelling. So how do they “be beautified”? One worker carried a water tank to “shower” the bottom side of the train, while the other “bathed” with a towel. The next day, the cleaned bullet trains will be able to carry passengers to the destination.

These tools are the treasure of motor train mechanics. They are like surgeons’ scalpels and stethoscopes. The heavier tools are more than ten jin. “Doctor Bullet Train” fight with them side by side to protect the safety of bullet train operation.

It’s 24:00 in the night, and several motor trains are still outside side by side, waiting for cleaning and maintenance. At dawn, they will wash away the wind and dust, say goodbye to “injuries” and carry thousands of dreamers to realize their dreams. (Translated by Luo Juan, Fathom Language Limited)
