Here are some archival photos from the constructing of the first line of the Moscow underground.
Sometimes it is hard to distinguish where are the upper sides of the pictures and where are its lower parts, because photos are black-and-white and very old.
Cofferdams. The plate “Hairdresser’s” is in the background.
And in the foreground you can see a mine.

Workers are even without helmets, but it was normal for that time.
The process of ramming in the rabbet.
Preparations of the calotte for concreting.

The mine shaft. Pay attention to the crack in the wall that is indicated with arrows.
Concreting of the shaft.
Buntons are pressed by the mountain pressure.
Maybe it is the delivery of the rock to the top.
The radiator installation.
The arrangement of the mine. Workers hadn’t any safety equipment!
The building of a metal rabbet.
An arch lock.
Examples of the oblong rock.
A winch of a cage hoist.
