Reconstruction of station
From September 26, 2005 to May 15, 2007 the southern lobby of station has been closed on reconstruction.
The eskalatorny inclination conducting on station is completely reconstructed. The base of escalators has been dismantled and built anew, on it have installed the upgraded escalators with balustrades from stainless steel and the improved technical characteristics.
New escalators completely meet all norms and safety requirements, have considerably the best design and lower energy consumption. In the machine hall of escalators have installed modern control panels.
Because the lobby of station is built in the building of a concert hall of P. I. Tchaikovsky, works on dismantle old and installation of the new equipment have been connected with certain difficulties — narrow dimensions of a land lobby haven't allowed to carry out delivery of the large-size equipment to the machine hall of escalators in the traditional way. Therefore were the decision to lift large elements from below on an eskalatorny inclination is made. The drive of each escalator has been divided into 3 parts: bed, reducer and main shaft. Delivery of separate parts of the drive to station was made economic by trains from Sokol electrodepot at night.
From the level of a platform of station large-size elements of the drive by means of winches rose upward to the machine hall of escalators where there was an assembly and adjustment of the drive.
In a lobby the new cash desks equipped state-of-the-art are constructed, modern turnstiles of UT-2005 are established.
During reconstruction all cable, sanitary and ventilating communications have been completely replaced, service premises are repaired, devices of the fire and security alarm system are installed.
Along with reconstruction of a lobby works on restoration of the station with return of initial shape to her have begun. The opening of the second exit preceding it has allowed to carry out works without closing of station for passengers.
Marble floor has been replaced by more resistant granite, having accurately repeated at the same time the ornament which is thought up by the architect of station Alexey Dushkin. Columns and various decorative elements of station are updated. Among them more than 30 mosaics created according to Alexander Deyneki's sketches — experts not only have cleaned them, but also have restored some missing details.
