Metro. The Underground City.

The metro is the fastest type of urban transport. Probably, everyone has had to use it at least once. But not everyone has thought about the fact that the metro is a whole underground world, huge, complex, and very interesting.... This book, rich in diverse information, helps to get to know it better. It is dedicated to the Moscow metro, opened in 1935, which is considered the most beautiful in the world. The reader will learn about where the first "subways" appeared on our planet and what they were like, how the metro was designed and built in Russia, how underground routes are laid, what "quick-sands" and "tunneling shields" are, which objects connected the first lines of the Moscow metro, and what happened at the metro stations during the Great Patriotic War. A lot of interesting information is presented in the book about how clean air is supplied in the metro, what unique lighting fixtures are installed at different stations, how over time the carriages, escalators, turnstiles, and tickets have changed, and finally, where trains spend the night and how the safety of passengers is ensured. And, of course, the author talks about the discoveries that can be made in this extraordinary museum underground.
