Обережно, двері зачиняються!

Have you ever taken the subway? Maybe you are afraid of the roar of an underground train that disappears into the blackness of the tunnels? Or maybe you are comforted by this timeless space, where there is neither day nor night?...

They say that at night, when the subway is already closed, you can sometimes hear the sounds of a train. But it cannot be a train, because the last one has already passed? Besides, there is only sound. The train itself is never seen.

Superstitious workers say that this is a bad omen, and at night they try not to listen too much. But it seems that not everyone believes in it.
