In our daily life, trains are undoubtedly one of the most convenient means of transportation. It takes us through the city, connects the countryside, and witnesses the hurried journeys of countless people. However, when we sit in comfortable seats and enjoy a smooth ride, have we ever wondered where the "output" on the train goes?
Once upon a time, the "smell" of trains was a topic that passengers avoided and avoided. That unique smell seems to be able to travel through time and space, making people instantly return to the era when there was no air purification system. I remember the older generation used to say, "The train runs fast, but the toilet can't keep up." Although this sentence is straightforward, it expresses the embarrassment of that era.
In fact, the excrement on the train does not "contribute" so directly to the tracks. On modern trains, each carriage has a special dirt disposal system. These systems are like a small sewage treatment plant, collecting our "inconveniences", and then through a series of high-tech means such as high-pressure washing, chemical treatment, etc., the sewage is converted into a biodegradable liquid, and finally transported to the receiving facility on the ground through special pipes.
This process may sound incredible, but it is made both efficient and environmentally friendly thanks to the efforts of the engineers and environmentalists behind the scenes. They use the power of technology to change this small detail in the train journey, so that we can enjoy comfort at the same time, but also less troubled by peculiar smells.
Speaking of this, I can't help but think of a famous saying: "Human progress often stems from the solution of inconvenience." "The innovation of train sewage technology is the embodiment of this progress. Not only does it enhance the travel experience, but it also shows how we can grow to find greener solutions.
Of course, with the development of society and the improvement of environmental awareness, people's requirements for toilet hygiene are getting higher and higher. Today's EMUs and high-speed trains are even equipped with advanced vacuum collection systems, which have almost zero emissions. Such a change will undoubtedly make our journey cleaner and make our home planet more carious.
So, the next time you're on a train, thank the unknown engineers for their hard work and making our "troubles" less of a hassle. And when the train is whizz by, you just need to enjoy the journey with peace of mind and no longer have to worry about that "old" question.
Finally, let's end this little article with a lighthearted sentence: "The story on the train is sometimes hidden in those unseen places." "Like and retweet, let more people know that our travel is becoming greener and more humane.
