Recently, subway photos uploaded overseas have become an issue, and our country’s subways are becoming the object of envy. In our country, it is so natural to wait in line when waiting for the subway, but in the US, they say you wait with your back against the wall.
The reason is said to be the recent surge in subway pushing, which involves pushing people waiting onto the tracks as soon as the train enters.
It is said to be one of the crimes that do not ask. Our country’s subway, which is considered the best in the world, has screen doors installed at almost all stations, so there is no need to worry about such crimes. It is said that foreigners are quite surprised and envious because it is a part that is really hard to see overseas.
In Korea, most screen doors were installed starting in 2002 for the purpose of accident prevention, and most of them were installed throughout the 2010s. Not only do they prevent accidents, but they also provide perfect soundproofing, dustproofing, and unexpected waterproofing, and they even prevent trains from flooding, and they block the air from the outside, reducing heating and cooling costs by nearly 30%.
The US is also trying to install screen doors, but the gap between doors is different for each subway and the platforms are also different, so the installation cost per station is nearly 10 times that of our country, which is causing great difficulties. I feel grateful once again for the various convenient facilities in our country that I thought were natural.
