During the Spring Festival in 2024, rain and snow across the country have brought great inconvenience to people's travel. Many high-speed rail lines have experienced large-scale delays or even shutdowns, which has disappointed many travelers. However, at the same time, the "green car" around him was able to fly all the way through the snow and arrive at the destination on time. This makes many people wonder: why can the green car remain stable in rain and snow?
Let's first learn about the history and characteristics of the green car. The green car is a type of train on Chinese railways, and its history dates back to the 50s of the last century. Although China's railway technology has developed rapidly over time, green cars are still widely used on certain lines and regions. The main features of the green car include lower speed, less comfort, and older technology. However, it is these characteristics that make the green car show high stability and reliability in rainy and snowy weather.
Let's take a look at why the green car can go all the way in rain and snow. First of all, the speed of the green car is relatively low, so it is more adaptable to rain and snow. In rainy and snowy weather, the lower speed can reduce the risk of train skidding and loss of control, thus ensuring the safe operation of the train. Secondly, the coefficient of friction between the wheels and the track of the green car is large, which also contributes to the stable operation of the train in rainy and snowy weather. In addition, the powertrain of the green car is relatively simple, so it is easier to maintain and maintain in rainy and snowy weather, reducing the occurrence of delays or downtime due to equipment failure.
Of course, green cars also have some disadvantages in rainy and snowy weather. Due to its older technology and less comfort, there may be some minor breakdowns or discomforts during the operation of the green car. However, due to its high stability and reliability, the green car has still become the choice of many travelers.
