Why does the last subway train in Beijing need to run empty?

In many places, the subway has a habit, that is, when the last bus is empty, the subway will still drive around empty. Many people may not understand that there is no one on the subway. Why run another lap when the car is empty? Later, there were gradually some rumors that the subway was empty and pulled ghosts. Is it true that the last train of Beijing subway pulls ghosts? Why did the last subway take a lap?

As we all know, the subway is called subway because the subways in all cities are built underground. The crowded subway is busy during the day, but at night, the empty subway will look a little scary. Moreover, the underground has always been a place with heavy yin, so there are more and more strange rumors about the subway.

According to legend, when the Beijing subway was just built, because the national conditions were still unstable at that time, many dead ghosts were still wandering around the world, so I heard that many strange things happened when the subway was just built. Some construction team members were injured inexplicably, and some dug bones under the tunnel.

Later, after the subway was completed, in order to prevent similar things from happening again, I asked several Taoist priests to help me see what was going on. The monk gave such a suggestion, that is, make a temporary empty car every night before the subway closes, and then drive around empty as usual. This car is not for people, but for ghosts.

The last bus that goes around empty is to let the disturbed ghost sit, then go where you want to go and have a good rest. This is how the ghost-pulling incident on the last train of Beijing subway came about.

Of course, rumors are just rumors. Professionals say that the reason why the last subway train needs to go around empty is not the so-called ghost-pulling problem, but only because of the need of subway maintenance. Driving around in the air is to let it go back to the garage or factory for maintenance, as if doing some hot sliding experiment. In short, it's not as mysterious as rumors, so don't be afraid to take the subway at night.
