Why is the subway not separate from the door and out?

This is because the two sides of the door are used to go up and down separately, but both sides of the platform are required, and the area is large. But in fact, the entrance and exit of the subway are separated, but because the subway does not arrive at the station, it is not divided. <>

This is just for the convenience of passengers, if there are people who can go up and down at the door, then this will only cause more inconvenient traffic, waste the time of passengers per public, and waste the time of subway travel. <>

Because the subway is already very long, if you separate the doors, it will cause a certain traffic jam, and it is not easy to manage, it will be easy to mess, and the subway stop time is too short.

Because if there are doors on both sides of the subway, many people may not be able to distinguish it, which will bring a lot of trouble, and it is also very inconvenient for its management and operation, so it is better to set up one person.

Because there are a lot of people on the subway, if you separate the door and the door, it may cause some people to not be able to get on and off the train in time, which will be particularly inconvenient, and it will be easy for people to make mistakes, which will bring some trouble to the subway work.

The order of the subway in our country is still relatively good, and the average person knows how to let the people get off the train first, and then get on the train by themselves, and it is not particularly crowded, and there is no need to separate the door from the door.

Because if the exit and entry of the subway are separated, the mentality of standing on both sides and waiting for people is very complicated, and the subway passage does not have so many aisles, if it is separated, it is too complicated and easy for people to distinguish.

It may be because this is more in line with economic benefits, and it will also save everyone's time, Chengdu Metro Line 1 will open the doors on both sides at Tianfu Square Station, and the side of the person will be delayed for about two or three seconds on the side of the person.

Personally, I think that when it comes to spanning multiple land parcels with different tenures, it is often necessary to reduce the size of the platform as much as possible. In addition, the increase in the platform area also means an increase in the space for equipment, evacuation and fire protection.

The easiest way to encounter this problem is to listen to the newspaper station.

Generally speaking, when the subway train announces the station in front of the station with a bilateral door, it will be specific to the left and right**, for example, Guangzhou Metro Line 3 Tiyu West Road, from the airport north to Tiyu West Road when transferring to the bilateral door, the voice will be different from the place to open the door on both sides when reporting the station in front of the station.

If you don't notice the voice in front of the station, then just go down and ask the subway staff, at most it's just a waste of time.

History. In 1860, construction of the first 6-kilometre tube between Farringdon Street and Bishop Road in Paddington, London, began, using the method of excavation and backfilling.

Opened to traffic on 10 January 1863, the world's first underground railway system, the London Metropolitan Railway, carried 9.5 million passengers in its first year of operation.

Since electricity was not yet widely available at that time, the underground railway had to be pulled by steam locomotives, and because the exhaust gases released by the locomotives were harmful to the human body, the designers at that time had a big brain, and the tunnel had ventilation slots that opened up to the ground at intervals.

Observe the text above the subway door, find the station that needs to get off, and the indicator light on the door can be opened. Pay attention to the sound of the subway announcement, and when you arrive at the station, you will be prompted which way to get off the train. If you really don't know, you can ask the staff for help and ask for clarity before getting on the subway.
