Where does all the excrement from the train toilets go? Why doesn t the track stink?

Limited express trains or older trains are usually lined up directly on the roadbed and do not do anything. The garbage generated by the toilets of high-speed rail, high-speed rail, direct express trains and some newly built express trains in recent years is concentrated in the garbage bin, and after arriving at the terminal station, it is sucked up by a special sewage suction truck and disposed of together.

Toilet feces from trains are generally discharged directly to the roadbed without any treatment. Because the speed of the train is very fast, it hits the gravel of the roadbed at high speed, and immediately turns into powder and basically disappears. However, if the speed is too slow, it will pollute the environment, so the toilet must be closed when the train stops.

A long time ago, when we went to the toilet at the train station, we could see air under the mouth of the iron toilet and gusts of cold wind howling. But at that time, it was directly discharged on the track, and how could I not see the slightest trace, which involved quite professional knowledge. In the beginning, the train was straight-through, and the underside of the train toilet was open, directly connected to the outside, and urine and feces were discharged directly to the railway, which is why the train was not allowed to go to the toilet after entering the station.

This is because trains travel very fast on the tracks, and even if our excrement has just fallen on the tracks, it will be broken down into small particles by the high-speed air currents. That is, the original pimple has turned into very loose feces. It's because they're so small that we can't see the excrement on the tracks, but if you lie directly on the tracks or kiss the dirt near the tracks, you're likely to smell something.

And although this method of disposal is simple, it is not environmentally friendly, and those things in human waste that are not good for the environment will not be decomposed because of this.

For high-speed trains, bullet trains, direct express trains, and some newly built express trains in recent years, the toilets use vacuum toilets, similar to those on airplanes. The feces are concentrated in the bins under the train. When the train arrives at the station for a break, it is processed by professionals and the collected feces are discharged to a designated area.

The whole process is simple and environmentally friendly, and does not have any impact on the residents on both sides of the railway.

All lined up outside the train, on the tracks or in the field. Because there are regular cleaning staff, and nature is divided.

The excrement is piped to the excrement because they regularly clean the tracks every day.

All the excrement from the train toilets is discharged onto the tracks. When the train travels at high speeds, it generates strong air currents. When the excrement is exposed to strong air currents, it will be decomposed, so the track will not stink. However, the toilet is closed before the train enters the station.

Everyone must have taken the train on a regular basis, and they must have used the train's toilet during the train ride. My toilet does smell very bad, but if you look closely, you will see that the toilet hole of the train is very small, and it leads directly to the railroad tracks. So many people are very puzzled, the excrement of the train goes directly to the tracks, why doesn't the track stink?

In fact, this is also very easy to understand, because the train is running at high speed in the process, so under the action of the car, the feces may be directly decomposed, and in the open environment, the smell has long been dispersed. <>

The train is very fast when it is running, especially at high speed until it enters the station, so if someone runs out of toilet on the train and then presses the flush, all the excrement will be washed onto the tracks. In the process of running at high speed, the train will produce high-speed air flow, and then these excrements will be impacted, will be washed away at the first time, and then will be divided into countless small pieces distributed on the tracks, at this time it has basically been decomposed and has no taste. <>

And although the excrement will be sealed during the high-speed travel of the train, things like paper towels cannot be broken down and will remain on the tracks. But after a long period of exposure to high temperatures in the sun, these things will slowly become dry, and then they will lose their odor, and in the state of high temperatures, these excrements disperse very quickly. The excrement may slowly turn black on the rails, and then slowly disappear, leaving it largely odorless.

In addition, the area where the railroad tracks are located will also encounter rainy days, especially in the event of heavy rainstorms, the excrement on the rails will be washed away and decomposed. Although most of his people only see some stones when they look at the results, there is actually a lot of dust on the rails, and some stones and dust around them will fly up when they are not driving, and then these dust may directly cover the excrement and be buried directly, so there is no smell.

These tracks are cleaned by someone on a regular basis, so they naturally don't smell bad. The current railway management is really very strict. And that's a good thing.

Because the track is open-air, it won't drop too much dirt at one time, and it will evaporate quickly after it falls, so it doesn't smell.

Because the things on the track are cleaned up every day, and some of the excrement has been weathered, and it doesn't emit any stench at all.

When we take the train, do you have such a question, where does the excrement on the train go? At first, I thought that there was a special ground staff to collect it at the station, because before entering the station, the toilet would be locked and opened only after the train started, I thought that on the one hand, it was to get on and off passengers, and on the other hand, it was to clean up the excrement in the toilet.

Later, I learned that the toilet of the train is straight-through, and the excrement in it will be discharged directly to the rails, but speaking of this, it raises a new question, in the long run, won't the rails be dirty? But when we walk on the tracks, we don't smell anything, we don't see any droppings, where do they go?

Train feces do not discharge on the tracks before and after entering the station.

When we walk on the railway tracks in the city, we don't see a single feces at all, because the excrement on the train does not reach these sections, which is why the toilet is required 15 minutes before and after the train enters the station.

It is forbidden to use the toilet during this time, otherwise the feces will be discharged into the crowded area, you must know that the train has to go a long way in 15 minutes, lock the toilet to prevent dirty a long track in front of and behind the platform, so you can't see any feces, because the section of the track you are walking on has no excrement discharged.

Therefore, the feces on the train are basically lined up in the sparsely populated wilderness, and few people go to those places, so naturally you can't see or smell!

When the train is running at a low speed.

If the train runs at a low speed, some excrement will fall next to the tracks, but nature has a cleaning function, and after a few rains, the excrement on the track surface will soften and flow into the soil with the rainwater to become organic fertilizer!

When the high-speed rail needs to pump sewage, it should be parked on a special strand road, and a sewage pumping unit corresponds to a carriage, so that the pumping work can be completed quickly. The pumping work is carried out at night, because the high-speed rail needs maintenance at night, and it is not running, and the pumping work is just in time.

Although the sewage pumping work is carried out by equipment, and the powerful sewage pumping pump is generally no problem, because some passengers will throw foreign objects such as sanitary napkins and large paper towels into the toilet, which will cause the blade of the sewage pump to be unable to break the foreign matter and become blocked, so the standby pump unit must be used immediately to continue the sewage suction operation.

Some of the larger dirt will stick to the rails and be dried by the sun, and the railroad workers will also clean it up when they are maintaining.

Washed by rain, decomposed and dried by sun exposure.

The feces that are decomposed by the high-speed air flow will still fall on the railroad tracks, but the years of sun exposure and rain will slowly decrease, or even disappear, and will also be dried by the air.

However, due to the above reasons, the smell on the train is not too strong, so even if we have the opportunity to pass by on the train tracks, we will not smell much in the open environment.

Because these things are cleaned every day, and the friction of the rails can produce high temperatures, and there is a lot of grace when the speed is fast, these things will be blown dry quickly after touching the tracks.

Because the train is very fast when it is running, and these things dry after hitting the tracks, the smell is naturally gone. It's because it's fast.

Because the track has a very good ventilation effect, the excrement will dry out, so it is difficult to stink.

Express or older trains, usually run directly onto the roadbed and do nothing. The excrement of high-speed rail, bullet trains, direct express trains and some new express train toilets in recent years is concentrated in the sewage box, and after arriving at the terminal station, it is sucked up by a special sewage suction vehicle for centralized treatment.

The excrement from the toilet on the train is generally discharged directly to the roadbed without any treatment. Because the speed of the train is very fast, it hits the gravel of the roadbed at high speed, and immediately becomes powdery and basically disappears. However, if the speed is too slow, it will pollute the environment, so the train has to turn off the toilets when it stops.

High-speed rail, bullet trains, direct express and some new express trains in recent years, the toilet uses a vacuum toilet, which is similar to the toilet on an airplane. The excrement is concentrated in the dirt box under the car, and after arriving at the terminal, it is sucked up by a special sewage suction truck for processing.

The toilet on a train is usually between the two carriages of the train.

High-speed rail, bullet trains, and ordinary trains all have toilets, and some high-speed railways have toilets and squatting toilets to meet the needs of different people, but most of them are toilets, equipped with disposable toilet paper pads, generally near the toilet, just look at the instructions. If you can't find a toilet, you can also ask the staff on the train, and the toilets on the train are basically in an in-line setting.

When passengers use the toilets, excrement falls directly on the tracks, so in order not to pollute the environment inside the station, the toilets are turned off before arrival and departure. With the continuous development of society, this problem is also slowly being solved, and by 2021, some trains have adopted vacuum toilets.

Precautions

1. The toilet is not manual, and there is no need to rely on yourself to flush the sliding door, and the switch button will be instructed to be pressed on the wall. The door is also closed by the door button inside, and the anti-lock safety pin must be closed.

2. No smoking signs are posted everywhere, don't smoke in the toilet by chance. There are smoke detection devices. Once it rings, it will have a great impact and cause all kinds of damage.

3. Don't misread the instructions, especially the emergency button and flush button, the words "help" and "emergency" are not flushing buttons, and often passengers will press them as flushes, so be sure to confirm them before pressing them.

4. When you go to the bathroom on the high-speed train, take care of the important items around you to avoid being stolen.

5. Within five minutes before and after the train enters or leaves the station, the toilet is not to be used, and you should pay attention to the time before going to the toilet.

There are special containers for collecting excrement on the train, and the excrement is disposed of at the station when the train arrives.
