High-speed trains are ok, but a few trains are not.
In the early days, the train toilets basically used straight toilets, that is, the excrement directly led to the track under the train. When the train stopped, the toilets were forbidden to be used.
Now, the train going to the toilet has undergone earth-shaking changes, and more and more trains have begun to adopt the toilet collection device, which is a huge turning point. High-speed trains, bullet trains, through express trains and some fast trains newly built in recent years, the toilets use vacuum urinals, which are similar to the toilets on airplanes, and there will be inhalation sound when flushing.
Operating principle of toilets in moving stations
The vacuum excrement collector is responsible for compressing excrement and other dirt, conveying them to the dirt box, and then pumping them away by the dirt truck for centralized treatment after arriving at the station. When the bullet train stops at the station, the toilet can still be used normally.
the toilets of emu trains are located at both ends of each car, including toilet and squat toilet. It should be noted that the toilets on the train are not divided into men's toilets or women's toilets.
At the same time, the electronic screen above the carriage will display the usage of the bathroom in real time. When the humanoid sign shows green, it means no one, and when the humanoid sign shows red, it means someone.
