When the train is moving at high speed, the windshield often sticks to flying insects in the summer, and it will be full of rain and snow in the winter.
Some netizens asked: "What should I do if the train glass is dirty?" Do you spray glass water too? How do you wipe the glass after the train has been running for a long time? The Xinhua News Agency reporter came to the Shenyang North EMU of the Shenyang EMU to reveal how the train cleans the glass.

Netizen: What should I do if the train glass is dirty? Do you spray glass water too?
Reporter: Trains and cars need to use glass water when cleaning glass, but the glass water used in trains is a special glass water, every 4 liters for a bucket, with high-strength insect carcasses, gums, bird droppings. Since the Tohoku winter is very cold, ordinary glass water will freeze, so in winter, glass water with a cold tolerance of minus 40 degrees Celsius will be used, and in other seasons, non-cold resistant glass water can be used.
In addition, the windshield of the EMU train is densely packed with additional equipment, which has its own heating function, which can reduce the frost and fogging on the glass during the train driving.

Netizen: The glass of water of the train is added from**? Do you want to lift the hood?
Reporter: As we all know, EMU trains have locomotives at both ends, so the locomotives at both ends need to be filled with glass water. However, they are separate and do not share the same glass tank.
Where is the glass water tank of the train? Taking the Fuxing EMU train as an example, its glass water tank is in the cabinet next to the inner door of car 1 and car 8, which reads "wiper water tank", the water tank volume is about 24 liters, and there is a liquid level meter on the water tank, which can indicate how much glass water is left.

Netizen: How do the wipers on the train work?
Reporter: Taking the Fuxing EMU train as an example, there is a wiper button on the driver's bridge, and through the control button, you can choose different wiper speeds. Before driving, the mechanic needs to conduct a wiper test to see if the wiper swing is stagnant, stuck, or unclean. Then press the water spray button to observe the water discharge status of the wiper outlet and check whether the water spray is normal.
In the next step, the mechanic opens the door of the "wiper tank" and checks for the absence of glass water. The same inspection process is applied to the driver's cab at the other end.
