Title: The "Glamorous Secret" on the Train: Why is there no smell near the tracks?
While traveling by train, we often encounter all sorts of surprising things. However, today I would like to share with you a true and interesting story about the "glamorous secret" on the train, which may make you laugh and be stunned!
That day, I boarded a train to my destination, and I was greeted by a lively crowd of passengers and a cheerful atmosphere. I found my seat and was ready to embark on an enjoyable journey. But when I looked at the scenery outside the train, I noticed something that opened my mind - there was not a trace of stench next to the tracks! Is this a fantasy journey?
Driven by curiosity, I decided to step out of my comfortable seat and solve this unbelievable puzzle. I followed the corridor of the carriage to the rear of the train. A breeze blows, and I feel a subtle fresh fragrance in the air. Could it be my delusion?
When I came to the carriage connection area outside the door, I couldn't help but puckle my jaw and fall into deep thought. You know, on the train, many passengers use the toilet, and the feces in the toilet end up on the tracks. This fact seemed to contradict my sensory experience. Why isn't there any smell near the tracks?
After some observation and reflection, I came up with a strange and alternative answer. It turns out that the friction created between the wheels and the rails actually creates a wonderful mechanism for "eliminating odors"!
We know that when trains are traveling at high speeds, there is extremely high friction between the wheels and the rails. And it is this friction that allows the train to maintain stable operation and overcome the limitations of the terrain. What's more, this friction turned out to be a key factor in eliminating odors!
When the manure discharged by the train through the toilet, the friction force quickly rubs and grinds it, which greatly increases the surface area of the manure. An increase in surface area means more contact surfaces, which allow the odor molecules in the feces to diffuse and volatilize rapidly.
In addition, the airflow generated by the train during its journey also plays a crucial role in eliminating odors. When the wheels rub against the rails, the resulting breeze quickly sweeps away the odor and blocks its passage through the air. In this way, even if the manure is discharged on the rails, it will not bother us with a trace of odor.
Of course, this wonderful mechanism does not mean that we can ignore hygienic conditions. After all, it is the responsibility of each of us to keep public places clean and hygienic. Only by working together can we make our journey more beautiful and enjoyable!
As the mystery in my mind was solved, I continued to enjoy my journey on the train. The scenery along the way contrasted with the whimsical train "Glamorous Secrets" made me make unforgettable memories along the way.
Perhaps, in future train journeys, when you catch a glimpse of the manure discharged onto the tracks, you will also remember this interesting story - the fantastic friction between the wheels and the rails creates a journey without smell. Let's enjoy every moment of our trip with laughter and curiosity!
