Skhodnenskaya (Russian: Сходненская) is a station on the Tagansko-Krasnopresnenskaya Line of the Moscow Metro. The station is a single vault, which was a significant engineering achievement and a change from the typical functionality design of the 1960s. Actually, Moscow's history of single vault stations began 40 years prior to Skhodnenskaya with Biblioteka Imeni Lenina which opened along with the Metro itself in 1935. Built to a design of the Paris Métro, however, problems of keeping the structure from collapse and pouring in bitumen called for no repeat of such methods. The second single vault, Aeroport, opened in 1938, was built with the cut and cover method, and was not successful.
