This Russian subway map card came from Gaby from Germany (via Postcrossing). A nice addition to my subway map card collection. 😀
The Moscow Metro 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 2013, the Moscow Metro has 188 stations and its route length is 313.1 km. The system is mostly underground, with the deepest section 74 metres at the Park Pobedy station. The Moscow Metro is the world’s third most heavily used rapid transit system after Tokyo subway and Seoul Metropolitan Subway.
