As the Spring Festival approaches, a sudden large-scale snowstorm in the south has made countless travelers who are eager to return home feel the difficulty of winter travel. At a time when the high-speed rail has slowed down and stopped due to the blizzard, a ** has sparked heated discussions on the Internet - an old green train is speeding as usual in this snowstorm, like a train "grandfather" through time and space, calmly showing its unique adaptability and tenacious vitality to the world.
Recently, a netizen was trapped in a snowstorm on the high-speed railway, and photographed a picture of a green train on the adjacent track not afraid of the cold, not affected by ice and snow, and still moving forward steadily. This has sparked a deep public understanding of the difference in performance between modern high-speed rail and traditional green-skinned trains in the face of extreme climates**. How can the green train still run stably in such weather conditions? This phenomenon makes people wonder whether we should re-examine the traditional means of transportation that seem to be outdated, but in fact have special value, while technological progress is also possible.
From the perspective of train structure and power system, high-speed rail and green train can be described as completely different. The high-speed rail relies on advanced electric drive technology and ballastless tracks, and each carriage has an independent power unit to pursue high speed and high efficiency; The green train, on the other hand, uses the traditional ballasted track and a centralized power source, that is, the internal combustion engine or steam engine in the locomotive to provide power, which runs relatively slowly, but has high stability and is relatively less affected by changes in the external environment.
Secondly, in terms of energy, high-speed rail relies on overhead catenary or third rail power supply, and once the power grid is disturbed by extreme weather such as heavy snowfall, it may affect the normal operation of high-speed rail. In contrast, the Green Train, which is powered by its own fuel, is able to maintain basic operations even in bad weather, as long as the fuel is ensured**, and this self-sufficiency makes it more resilient to extreme environments.
In addition, due to the slow running speed of the green train, it has relatively low friction requirements when traveling on snow-covered tracks, so it can resist the impact of wind and snow on driving safety to a certain extent. At the same time, the areas where the Green Train lines are located are often located in areas with simpler infrastructure, lower maintenance costs, and faster recovery efforts in the event of bad weather.
In addition, the operating cost advantage of the green train is also reflected in the extreme weather. Compared with the high operation and maintenance costs that may occur in bad weather, the green train can adjust the operation plan more flexibly, respond to emergencies at a lower cost, and ensure uninterrupted service.
Although high-speed rail has become widely used in China and has become a symbol of China's speed in the new era, green trains still play an indispensable role in some remote areas, regional railways and special purposes. Whether it is a lifeline connecting the city and the countryside, or a special tourist train carrying historical memories and cultural characteristics, the Green Train continues to play its own role in its unique way.
The buzzard has made us re-examine the advantages and disadvantages of modern technology versus traditional methods under certain conditions. It reminds us that while we continue to pursue speed and efficiency, we must also see the practicality and resilience of traditional technologies in specific scenarios. For the future transportation planning and construction, how should we better take into account scientific and technological innovation and actual needs, how to rationally use existing resources and respect the unique value of each mode of transportation, is a topic worthy of in-depth understanding of the whole society.
Under the blizzard, the green train moves forward calmly, which is not only a vivid demonstration of the technical strength of traditional railways, but also a profound enlightenment for how we view and use existing resources. In this rapidly changing era, no matter how advanced technology is, it must be based on practical application scenarios and fully consider various unpredictable factors. Perhaps, in the process of our rapid development, occasionally stop and look back, the green figure through the wind and snow is reminding us to learn to respect and make good use of those seemingly old, but in fact tenacious forces, with a more comprehensive and inclusive vision of the development and progress of transportation.
