O Metro de Moscovo foi inaugurado há 80 anos

The Moscow Metro (Russian: Моско́вский метрополите́н]) is a rapid transit system serving Moscow, Russia and the neighbouring Moscow Oblast towns of Krasnogorsk and Reutov. Opened in 1935 with one 11-kilometre line and 13 stations, it was the first underground railway system in the Soviet Union. As of 2014, the Moscow Metro has 196 stations and its route length is 327.5 km. The system is mostly underground, with the deepest section 74 metres underground at the Park Pobedy station, one of the world's deepest. As of 2013, the Moscow Metro is the busiest metro system outside of Asia, the world's busiest by daily ridership and the 6th longest in the world.
