  "The G834 train is about to arrive at the station, stopping at No. 26, please prepare for the pollution suction staff!"

  At 7:10 on February 6, passengers traveling from north to south at Lanzhou West Railway Station were hurried, and hurried shouts sounded in the inconspicuous suction team lounge under the stairs of platform 22.

  "Train G834 is coming to the station, and the polluters have received it!" Chen Baotai, ground mechanic at the Lanzhou West Depot of China Railway Lanzhou Bureau Group Co., Ltd., picked up the walkie-talkie and replied.

  The sewage suction work is to extract the dirt in the sewage collection system of the EMU through the sewage suction unit to "empty the stomach and intestines" for the EMU, so that the toilets of the EMU can be used normally. Therefore, they are also called "the time of the EMU. Chuanxiang".

Chen Baotai, 51 years old this year, is responsible for the daily sewage suction work of 400 large and small toilets of 200 EMUs in the 17th group of Tuding at Lanzhou West Railway Station with 9 pollution suction personnel.

  Chen Baotai and colleagues put on protective vests, put on walkie-talkies, put on gloves, masks, picked up hooks, flashlights and other tools, counted the number of people, made various preparations, and jointly controlled the Lanzhou West Station Duty Room and waited for the EMU Arrive.

  At 7:34, the G834 Fuxing EMU slowly drove into Lanzhou West Station, Chen Baotai gave an order, and the nine sewage suction personnel who were already ready to go rushed to the sewage suction unit of each car and extracted more than 30 catties of sewage suction. Tube, lunge towards the EMU filth box, quickly insert the EMU filth box interface, and tighten the buckle.

Then skillfully open the suction hose and various valves of the dirt box to suck all the dirt away.

  At this time, even wearing a mask, the pungent smell made everyone frown.

  In order to do a good job of safety protection, Chen Baotai was observing the situation of the EMU on this line and the adjacent line, while reminding the suction personnel not to cross the adjacent line.

  "Whether it is windy or rainy, the 16 EMUs have only 25 minutes of dirt suction time. There are many stages in the suction operation, and the sewage suction port is often blocked. To ensure the safety and punctuality of the EMU, we can only Race against time!" Chen Baotai introduced.

  The sewage suction staff lined up and carried out the sewage suction operation in an orderly manner. They cooperated all the year round to make each other a tacit understanding. After sucking one sewage tank cleanly, they went straight to the next sewage tank.

At the sewage box of the 6th car of the G834 EMU, Yang Xueli, the leader of the sewage suction group, pressed the suction pipe connector with one hand and lit his face with a flashlight. He carefully observed the suction pipe through the light of the suction pipe. The flow of the liquid, while constantly observing the sewage suction tank through the liquid level indicator......

  Suddenly, the suction pipe made a "silk" sound!

  "Old Chen, Old Chen, the suction port of car 6 is blocked, take the iron hook!" Yang Xueli shouted on the walkie-talkie while quickly closing the valve and unplugging the suction pipe connector.

  Old Chen Xiao ran and took their "Treasure Box of Unblocking"-gloves, masks, iron wire, wrenches, etc., rushed to the suction port, and handed it to Yang Xueli. Yang Xueli squatted on the ground and stretched it to the suction port with a hooked wire at one end. In the depths, he kept stirring and repeatedly pulling out, finally hooking out the masks and towels stuck inside.

  "The sewage outlet is often blocked, masks, towels, diapers, instant noodles, forks and other strange things have been taken out. The suction work was originally time-intensive, and the dirt should not be spilled on the EMU and the ground. If you temporarily suck up the pollution, you have to rush to do it!" Yang Xueli told reporters, "I hope the news media can also remind passengers not to throw foreign objects into the bathroom when riding in the EMU!"

  Yang Xueli, who had dealt with the toilet blockage of 6 cars, rushed to the west side of the EMU, and the other 8 pollution suction personnel were waiting in line. Chen Baotai took the camera flashlight and checked again to confirm the closed state of the suction port cover and the suction unit cover of the EMU After confirming that all the dirt bins were emptied, he led everyone in line to the lounge.

  At this time, the first dawn of the morning shone on them.

Facing the rising sun, the G834 Fuxing EMU slowly drove out of Lanzhou West Station with passengers.
