The second entrance was opened in 1968, due to the landscape and the axis of the station platform to vestibule is done via two escalators and an interim mezzanine station that rotates the passenger traffic by 180 degrees. The large incline from platform to the mezzanine retains the three LT-4 21.4 metre (70 ft) high escalators. The 7 metre (23 ft) high smaller incline to the subterranean vestibule originally had three LP-6I escalators, but as this model proved troublesome after long use, it was prematurely replaced throughout the Metro during the 1990s. Lubyanka's turn came in 1995 and three ET-5Ms now soldier in their place.
