Why can t toilets be built in subway cars?

I think there are three reasons:It is not practical, difficult and costly

2. The reason for the difficulty is that the feces will naturally emit peculiar smells and require a lot of manpower and material resources to deal with them.

3. If the toilet is designed in the carriage, there will naturally be a lot fewer passengers in a carriage, but the flow of people is so large, what should I do, then we can only increase the number of vehicles and increase the number of people.

Subway car, it is built underground, that is to say, the underground railway, as the name suggests, in the underground tunnel to carry out activities, if you build a toilet cleaning, the cost of maintenance is much higher than the train, and then the subway is basically a short trip, that is to say, the subway people are similar to take the bus, the longest will not do, more than two hours to build a bathroom is not much necessary, both waste time and energy and do not have much practical function, why enter the bathroom on the subway, It doesn't make much sense.

The subway is running for the first time, and the air circulation in the underground space is not smooth, and if you add a toilet to the subway car, the excrement cannot be collected in time, so the subway station will smell very good. The intervals between the subway stations are very short, and there are toilets at each station, so it is redundant to install toilets in the subway cars.

Because the subway is the same as the bus, they are very short in the process of driving, if you want to go to the toilet, you can go to the corresponding platform, there is a toilet in each platform, and in the subway is a toilet, the air pollution will be particularly serious, because there are still a lot of people in the subway.

On this issue, I think it is completely unnecessary to build a toilet in the subway car, because the travel time between the two stations of the subway is relatively short, you can get off the subway for convenience, and it is a great waste of installation costs and cleaning costs, there is space for this toilet can also allow more people to get on the train as soon as possible, so it is not a question of whether it is possible or not, it is a question of whether it is necessary!

If the inline rails, first, the speed is not reached! AT PRESENT, THE FASTEST SUBWAY DOES NOT RUN AT A SPEED OF 80 KM H, AND IT TAKES AT LEAST 130 KM H TO REACH THE WIND PRESSURE DECOMPOSITION, BUT THE DISTANCE BETWEEN THE TWO STATIONS IN THE CITY IS ONLY A FEW KILOMETERS.

Second, most of the subway is underground, which is not well ventilated, and some dirt is moldy and smells due to water accumulation.

If it is a vacuum collection, then it is necessary to bring large equipment, and at the same time the working power of the train must be increased, because in order to support the usual passenger flow and body weight, this also means that more energy will be consumed, so the transportation cost will increase, so you go to take the subway is estimated to be worth the price of a train to run a station.

Personally, I don't think it's necessary to build a toilet at all, because the subway generally runs for a short time, and there are men's and women's toilets at the stations and stops, so if you want to be convenient, you can choose to get off the train halfway to solve the problem, so it is completely unnecessary to build a toilet in the subway car.

The reason why there are no toilets in the subway car is mainly because it saves space and attracts more people, because the subway is a rapid rail transit system, so there are many stops at it, and there are toilets on these stops, so there is no need to build a toilet in the subway car.

The characteristic of the subway is that it is fast, so you can generally reach your destination quickly, and you can get off at any time in the subway, if you need convenience, you can get off the bus conveniently and take the next train, because the next train will come quickly and you don't have to wait long, so there is no need to build a toilet in the car.

Because the air in the subway is blocked, such as building a bathroom, in the summer, the flow of people is large, the weather is too hot, and then the smell of the bathroom comes out, and then no one takes the subway.

First of all, it can't be straightened, the cost of using a toilet is too high, it's not necessary, and there is a toilet at the station, so there is no need to have a toilet in the carriage.

For this problem, different places are different, for example, the subway in Beijing has a bathroom.

The subway is relatively fast, and there are quite a lot of people taking the subway, and the time to catch up with the commute is really not crowded, so even if there is a bathroom, the possibility of going to the bathroom is zero. Most of them require a short ride to reach their destination in a short time, and many cities have taken this into account, so there is no extra space to build a subway.

Because there is no need, the subway is very fast, and the time required between stations is very short, only three to five minutes to arrive. It won't take long to ride around 10 stops. So there is no need to set up a bathroom at all. When you get off the subway, there are usually public restrooms.

Some subway stations can only go to the toilet when leaving the station, but in order to maintain the environment and objective needs in the carriage, the toilet cannot be put at all.

Because I think that first of all, the subway is a short-distance means of transportation, if it is an opportunity in the subway car, upgrading is a big problem for cleaning, so we must consider the cost of this aspect, rather than blindly trying to make it convenient.

There are many subway stations, unlike the high-speed rail that stops at least half an hour, and the subway stops every three or four minutes. I really can't help it, I can quickly get off the bus at the current stop to go to the toilet, and then sit down after I finish it.

The train takes only two minutes to get to the next station, and there are toilets at each station.

The subways are all short distances, and if you really want to go to the toilet, you can take the train at any station along the way.

The question is like why the bus doesn't have a toilet!

Drain the feces on the tunnel, it's so dark inside, who do you want to clean up?
