There are two land lobbies [1]. One of them is located in the building of the Kazan station. Another (opened in 1952), combined with a lobby of Komsomolskaya station of the Ring line, comes to Komsomolskaya Square, and is placed between buildings of the Yaroslavl and Leningrad stations. At present because of extremely high passenger traffic the lobby works only for an exit of passengers. For an entrance the underground passage as the lobby of station didn't cope with a huge passenger traffic is converted. Till 1952 on his place there was a northern lobby (architects A. M. Rukhlyadev, V. F. Krinsky, artists V. A. Favorskii and A. G. Ivanov) opened at start-up of the first line of the Moscow subway. This lobby of original architecture hasn't remained up to now.
The lobby in the building of the Kazan station is connected with an end face of station ladder marches, the lobby between the Yaroslavl and Leningrad stations has escalators.
