The original three 28.4 metre (93 ft) high N-type escalators were replaced in 1994 by ET-3M models. The works included a renovation of the vestibule. The second entrance was built into the ground floor of the Red Gate skyscraper, designed by architect Alexey Dushkin and opened on 31 July 1954, the architecture carries resemblance of the more flamboyant Stalinist style. Due to the landscape of the region, it required the escalator tunnels to be split. As a result, there is a small incline that follows the axis of the station (3 x EM-1M escalators, 11.5 metres {37 ft} high) and a great incline that brings commuters to the ground level (3 x EM-4 escalators, 18.5 metres {60 ft}). It is scheduled to close for renovation in January 2014 which would include the replacement of escalators.
