The Moscow Metro   is an off-street rail (mostly underground) city public transport on electric power, located in Moscow and partly in the Moscow Region. It is historically the first and the largest metro of the USSR and Russia. The Moscow Metro is the sixth largest in the world in terms of intensity of use after the subways of Beijing, Tokyo, Shanghai, Seoul and Guangzhou,  and the fifth in the length of the lines in operation.

It consists of 14 lines (four of which will subsequently be connected in pairs; two lines are temporarily connected now, organizationally operating as one route) with a total length of 381 km in double-track terms, excluding the monorail and the MCC.  44 stations are recognized as cultural heritage sites, and more than 40 are architectural monuments. By 2023, another 35 stations should be built according to the plans of the Moscow government.

Nowadays, the total length of all 12 metro lines is about 325-330 km, and consists of almost 200 stations. By 2020, this number is planned to increase by more than 70 stations that is 160 kilometers longer than now.

Almost all stations are underground, only 9 of them are on the surface of the earth (right on the ground) and 5 stations are generally above the ground (for example, bridges).

The gaps between stations differ in length. For example, the longest distance is from Krylatskoye station to Strogino station (6.5 km), the shortest part  is from the Mezhdunarodnaya (International) station to the Delovoy Center (Business Center) station (only 0.5 km).

The first line opened on May 15, 1935 and went from Sokolniki station to Park Kultury station, with a branch to Smolenskaya. So far, the last metro line Butovskaya was founded only 12 years ago, in 2003.

The first passage between stations was finished  in 1938. It was a transition from the "Library of Lenin" station to the "Alexander Garden" station.

At the beginning, the controllers were manually checking all the tickets.

The subway trains are manufactured in the urban town of Mytishchi.

The "Myakinino" station is the only one  located outside  Moscow, in Krasnogorsk district. According to the plan (approximately by 2020), it is planned to complete and open one more station in the Moscow region, Mytishchi-Chelobitevo area, which will be the next after Medvedkovo station.

The deepest metro station is considered to be the "Victory Park" with the depth of about 90 meters. It also has the longest escalator (about 140 meters).
