Winter is the coldest season of the year, but it is also the most beautiful season of the year. Covered in snow and covered in silver, it adds a touch of poetry and romance to the earth. However, for the railway, winter is the most difficult season of the year, especially in some areas in the north, heavy snow, freezing, wind and other bad weather, to the operation of the railway brought great challenges and risks. In such an environment, there is one kind of train that has shown amazing adaptability and resilience, and it is the familiar green train.
The green train refers to the 25B type and earlier single-deck ordinary speed trains, the appearance of the body is dark green, and the speed varies depending on the model. The general express trains, rapid trains (K), express trains (T), direct express trains (Z), some tourist trains (Y) and some suburban trains (S) using new models such as 25G K T are not green trains in nature. Green trains are veterans of China's railways, they were once synonymous with China's passenger trains, and they are also the witnesses and strugglers of China's railways. Although they are old, they also have an irreplaceable role, they provide convenience and help for remote areas and poor people, and they are the "poverty alleviation public welfare vehicles" of the railway.
The reason why the green trains can run tenaciously in the snow and ice is because of their unique structure and design, but also because they have professional maintenance and security. Next, we will reveal the secrets of the Ice Warriors of the Green Train.
First of all, the structure of the green train is relatively simple, there is no complex electrical equipment and electronic control system, so it is not susceptible to the impact and damage of ice and snow. The wheels and bearings of the green train are made of metal and will not deform or break due to temperature changes. The windows of the Green Train are all openable and will not be unable to open due to icing. The doors of the Green Train are manual and will not fail to open and close due to circuit failures. The locomotives of the green trains are all steam locomotives or diesel locomotives, and they will not stop running due to lack of electricity. The carriages of the Green Train are made of wood or steel, and will not deform or collapse due to the weight of snow and ice. Secondly, the design of the green train is reasonable, with good frost protection and heat preservation capabilities, so it will not reduce comfort and safety due to ice and snow. The body of the green train is painted with anti-rust and anti-corrosion paint, and will not rust or corrode due to snow and ice. The roof of the green train is tilted at a certain angle, so that the snow will not increase the wind resistance or affect the view. The windows of the green train are double-glazed, so there is no reduction in light transmission or increased heat loss due to snow and ice. The carriages of the green train are equipped with kerosene lamps or electric lights, and there is no lack of lighting or heating due to snow and ice. The carriages of the green train are all quilted or blanketed, so you will not feel cold or uncomfortable due to snow and ice. Finally, the maintenance of the green train is relatively standardized, with a complete maintenance and support system, so there will be no breakdowns or accidents due to ice and snow. The drivers and attendants of the Green Train are seasoned veterans and are prepared for all kinds of bad weather. The Green Train operates according to a strict timetable and signaling system, and there will be no delays or misses due to snow and ice. There are professional patrol and snow removal personnel along the green train, and there will be no jams or derailments due to ice and snow. The platforms and waiting rooms of the Green Train are well equipped and serviced, and will not be lacking or inconvenient due to snow and ice.
To sum up, the green trains are the ice and snow warriors of China's railways, and they run tenaciously in the ice and snow, providing a safe, comfortable and convenient travel option for the majority of passengers. Although they are not as fast, advanced and luxurious as high-speed rail bullet trains, they have their own charm and value, they are the carrier of the history and culture of China's railways, and they are the memory and emotional sustenance of Chinese. We should cherish and respect the green trains, and we should also thank and praise the green trains, because they are our ice and snow heroes and the light of our railways.
