A decision on the construction of the Moscow Metro was made following the report of Lazar Kaganovich, a Soviet politician and one of the main associates of Joseph Stalin.
The new means of transportation was designed to improve the transport situation in city and partly relieve the tram lines.
Take a look at archival footage depicting how the first tunnels and railways of the Moscow subway were being built.
The Moscow Metro is not only an efficient means of transportation, but also a distinct example of the Soviet monumental architecture. The overall length of railway lines in the Moscow Metro is over 300 kilometers. This is equal to the distance from Vienna to Prague.
