Komsomolskaya is a Moscow Metro station in the Krasnoselsky District, Central Administrative Okrug, Moscow. It is on the Sokolnicheskaya Line, between Krasnye Vorota and Krasnoselskaya stations. It is located under Komsomolskaya Square, between the Leningradsky, Yaroslavsky, and Kazansky railway terminals. The station was named for the workers of the Komsomol youth league who helped to construct the first Metro line.

Komsomolskaya was built using the cut and cover method, with construction beginning on 3 May 1933. Temporary bridges were built over the construction site to avoid disrupting traffic, especially the numerous tram routes in the area. To counteract the high water table, the station was built on 636 piles which were driven into the saturated soil. The concrete structure of the station was completed by August 26 and Komsomolskaya opened on schedule on May 15, 1935.

Due to Komsomolskaya’s location under a major transit hub, the station was built with an unusual upper gallery above the platform to help handle rush crowds. The station has tall pillars faced with pinkish limestone and topped with bronze capitals displaying the emblem of the Komsomol league. The station was designed by Dmitry Chechulin, and a model of it was displayed at the 1937 Paris World’s Fair. [Source: Wikipedia]

The Moscow Metro is a rapid transit system serving Moscow and the neighbouring town of Krasnogorsk. Opened in 1935 with one 11-kilometre (6.8 mi) line and 13 stations, it was the first underground railway system in the Soviet Union. As of 2011, the Moscow Metro has 185 stations and its route length is 305.7 kilometres (190.0 mi). The system is mostly underground, with the deepest section 84 metres (276 ft) at the Park Pobedy station. The Moscow Metro is the world’s second most heavily used rapid transit system after Tokyo’s twin subway. [Source: Wikipedia]
