CCTV News: During the Spring Festival travel rush, behind the safe travel of passengers are thousands of sets of Mercedes-Benz EMUs across the country. During the day, trains travel thousands of miles a day, and at midnight, they enter the exclusive "maintenance station" for necessary cleaning. From inside to outside, the cleaners "take a bath" for the train overnight to ensure that they are clean and launched the next day. Next, we followed the reporter's camera to Nanchang, Jiangxi to check in to the "bathroom" of the high-speed rail EMU.

Since the front designs of different train models are different, the automatic car wash alone cannot achieve the effect of comprehensive cleaning, so after automatic cleaning, manual "scrubbing" is arranged. The cleaner Hu Honggui lifted up a long-handled cleaning brush more than 3 meters high, dipped it in car wash, and scrubbed the outer wall of the front of the car up and down. Hu Honggui has to repeat this action nearly a thousand times in one night. This year marks the tenth year that Hu Honggui, 49, has worked in this position. The accumulated experience over the years allows her to wipe the front of the car without leaving any dead corners within ten minutes.

Because you often hold the long-handled brush high, cold water often pours into the cuffs along the brush. In order to enhance protection, the cleaning staff will wear multi-layer gloves.

Large-area car skin cleaning consumes the most physical energy, while cleaning the roof equipment tests more care and patience. What the cleaners are wiping the insulators located at the top of the EMU. During the driving of the EMU, this part of the equipment is used to provide a source of electricity for the train. Once various dust, shellac and other dirty things are stuck, resulting in poor contact, it may affect the power use of the train. Cleaner Xu Sulian used a velvet cloth to gently wipe the uneven insulator surface layer by layer.

While work outside the car is underway, the cleaning of the passenger room in the car is also underway. From foot pedals to under the seats, from small tables to headsubs, the cleaners do not miss every detail and wipe every part cleanly. In order to give passengers a clean and tidy ride environment, cleaner Xu Guoying has to replace more than 300 headscarves every night. During the Spring Festival travel rush, the number of EMUs parked at the Nanchang West EMU every night increased from more than 70 to more than 100, and the workload of cleaners also increased.
