But 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 can no longer withstand the gravity, and the excrement falls directly into the track, and the platform will stink and become a large septic tank.
The disadvantages of this "in-line" toilet are obvious, not to mention polluting the environment, and it can also become a source of disease and affect 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.
However, since "vacuum-collected" toilets are often thrown into debris by passengers and clog toilets, a new type of work has been created in the railway sector: "toilet collectors".

Anonymous users2024-01-22Previously, trains were lined up directly on the roadbed.
Most of today's trains have a toilet collector, which is handled centrally at the end of the train.
Because human feces are organic matter, which can be decomposed in a short period of time, and the station of the train is relatively far away, and the nearest one is more than 10 kilometers, so the total area on this journey is tens of thousands of times larger than the area when the train stops, so when the train is moving, the feces can be excreted directly into nature >>>More
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. >>>More
Didn't deal with it.
The train's toilets are connected to the outside world, and excrement leaks directly into the roadbed through pipes. >>>More
The same septic tank sedimentation and purification treatment method as in China.
Hahaha, it's a matter of taste, and the taste is not small. It's been so long, and finally this problem has been noticed by curious netizens. Trains Everyone has sat on it, but some people still don't understand, don't know, don't know, don't know, but it's nothing, it's harmless. >>>More
