High-speed rail crossing the fog

Original title: Iron always responds to the impact of haze weather on high-speed trains: Strengthen equipment maintenance to ensure the safe operation of trains

According to the "News and Verticals" report, the Voice of the Central People's Broadcasting Service of China, China Voice, has launched a special live broadcast on the "Warm Home Road" for the Spring Festival in 2017. To Spring, tell stories about Spring Festival and respond to hot topics in Beijing, high-speed trains, and highways.

A group of pictures passing through the HSR high-speed rail some time ago were transmitted online. After the high-speed rail from Shanghai to Beijing passed through the fog and fog area, the white high-speed rail became dirty. A dirty high-speed rail on the Internet was really related to the smog. ?

Huang Xin, deputy director of the Operation Department of the China Railway Corporation Transportation Bureau, said that he also took the car and paid attention to relevant reports. He also pointed out that the continuous severe haze will affect the railway power supply system. The smog particles cover the power supply equipment. It is prone to fog flashes, which may affect the power supply and normal operation of the train.

Some passengers are concerned that from the previous smog situation, do they not need to wear masks when sitting in a high-speed train?

Huang Xin said that everyone’s concern may be “dirty and not dirty”. We are more concerned with safety. We have increased the frequency of maintenance of key driving equipment and ensured the safety of train operations in fog and haze. Under the circumstances, it will also adopt a speed-down approach to ensure safety. It may also cause delays in the train and hope passengers can understand it. At the same time, people are concerned about the high-speed rail ventilation system. The ventilation system of our country's high-speed railway EMUs is equipped with multi-level filter screens that can physically block dust. The concentration of dust inside the vehicle compartment is obviously lower than that outside the vehicle. Standards, we need not worry too much. Due to the high number of stations in the high-speed railway EMUs and the frequent opening and closing of the doors, some of the air outside the vehicle will enter the interior of the car, sometimes affecting the air quality inside the car.
