How do train toilets drain up?

Place a device on the train and take it off and wash it off when you get off the station. Train toilet straight track has been used in the history of the world's railway development, but later after the passenger train in developed countries went to the high-end and adopted a more hygienic and environmentally friendly toilet.

Precautions for taking the train:

1. Expiration date.

Ticket ValidityThe validity period of the ticket is calculated based on the mileage traveled. Within 300 kilometers is two days, and for more than 301 kilometers, each additional 500 kilometers will be added to one day, and less than 500 kilometers will also be counted as one day. When the changed ticket or expedited ticket is taken in advance, the validity period is calculated from the actual date of travel; In the case of a change of train, it will be calculated based on the date of travel specified in the original ticket.

2. Ticket visa.

If the passenger is unable to board the train on the date and train number specified on the ticket, he or she may go through the formalities of early or later boarding at the latest no more than 2 hours before departure without extending the ticket, speeding up the validity period of the ticket, and if the other countries are able to do so. Sleeper tickets cannot be changed. Passengers who change trains at transit stations and get off trains to resume travel should apply for a visa regardless of the type of train they take.

3. The luggage mainland is hungry.

The free weight of luggage passengers' carry-on items is 20 kg for adults and 10 kg for children. Carry-on items should be of sufficient length and volume to fit in the luggage compartment or under the seat. Explosive, flammable dangerous goods, items that disturb public health and pollute vehicles are not allowed to be brought into the vehicle.

Most of the toilets on the train are directly connected to the outside world, that is, the feces of the toilet are directly discharged to the roadbed, and will not do any treatment, but the sewage of the toilet will disintegrate when the train speed is high, but it will pollute the environment when the speed is slow, so the train must close the toilet when it is on the platform or close to the urban area.

At present, China adopts BSP and 25T and power supply 25G type train bottom, the toilet has adopted vacuum toilet, that is, the sewage of the toilet is no longer directly discharged to the rails, but temporarily stored in the toilet, and the train enters the garage after the unified treatment, so that not only the environment is protected, and the passengers are no longer troubled by the toilet closure.

Train toilet straight track has been used in the history of the world's railway development, but later developed countries have adopted more hygienic and environmentally friendly toilets after passenger trains have become gentrified.

Place a device on the train and take it off and wash it off when you get off the station.

At present, there are many toilets on trains, which discharge urine and urine directly onto the roadbed (the same is true for trains in many foreign countries). Therefore, when you flush the toilet on the train, you can often see the sleepers flying underneath directly from the toilet hole.

However, we hardly see feces on the rails, because under the action of the rapid air flow pressure generated by the high-speed running of the train, whether it is feces or toilet paper, it is strongly decomposed and thrown onto the roadbed on both sides of the railway, and even decomposed into very fine aerosol-like particles, which are dispersed in the air and integrated with nature. However, when the train is about to enter the station and the speed slows down, the conductor will lock the toilet and prohibit its use, because the pressure of the air flow generated by the driving force can no longer withstand the gravity, and the excrement will fall directly into the track.

It seems that the train tracks are really not a clean place, so I advise you not to run there and pretend to be depressed. As for those who lie on the rails and look for short-sightedness, don't they think the train tracks are filthy?

The disadvantages of "in-line" toilets are obvious, not only polluting the environment, but also potentially becoming a source of disease and affecting the health of railway maintenance personnel and nearby residents. Therefore, a more advanced "toilet type" toilet has been developed and used in Japan, the United States and some European countries very early. To put it simply, a "poop" toilet uses a huge vacuum suction to suck feces and odors into a "manure tank" at the bottom of the carriage.

When the car arrives at the end point, it is pumped and transported away by the sewage unloading system.

At present, all EMUs, high-speed railways, most of the Z-shaped trains (direct trains) use 25T trains, a small number of 25G trains (commonly known as "red cars"), which have been running along the line with high environmental protection requirements (such as Qinghai-Tibet Railway) using vacuum toilets, to achieve non-direct discharge.
