Using the Toilet on Moving High-Speed Trains

You can use the toilet on moving high-speed trains. Here is a detailed introduction to toilets on high-speed trains:

Toilet Types and Facilities
High-speed train toilets are unisex, offering both seated and squatting options for passengers to choose from based on their needs. There are indicator lights above the toilet doors; green means the toilet is unoccupied, and red means it is occupied, allowing passengers to quickly determine the toilet's availability. To enter the toilet, press the door handle to open the door, and be sure to lock the door once inside to ensure privacy. The toilets are well-equipped, with paper towels, toilet paper, and hand soap located below the mirror. Disposable toilet seat covers are provided next to the toilet seat, and they are easy to use—simply tear open the packaging and lay them down.

Usage Guidelines and Precautions
After use, the flush button is usually located next to the toilet seat or squatting pan; press it to automatically flush. High-speed trains use vacuum toilet technology, which has strong suction and can thoroughly clean the waste, so there is no need to worry about blockages. Used toilet paper should be thrown into the trash can, not flushed down the toilet, to avoid clogging the pipes or affecting the operation of the vacuum system. When leaving, unlock the door lock first, then pull the door handle to open the door and ensure the door is fully closed to avoid affecting subsequent passengers.

Waste Disposal and Eco-Friendly Design
The vacuum toilet on high-speed trains works on the principle of positive and negative pressure: when the valve opens, positive pressure pushes the waste into the waste tank; after the train arrives at the terminal station, the attendants connect the waste in the tank to a vacuum suction pump station through a dedicated pipe for non-polluting disposal. This design not only avoids the pollution of the track environment by traditional straight-discharge toilets but also ensures that the toilets can be used normally during the train's operation, including when it is entering the station, without having to be closed due to station stops.

Special Circumstances
Due to the high efficiency of the vacuum toilet, blockages or malfunctions in high-speed train toilets are rare. However, in case of equipment maintenance or emergencies, the train staff will notify passengers via announcements. Additionally, the space in high-speed train toilets is relatively compact, so passengers are advised to keep their usage time as short as possible to avoid occupying the toilet for an extended period and affecting others.
