To save the architectural appearance of cultural heritage stations is one of the main problems for the Moscow Metro. Development of station appearances is mainly connected to illumination devices that provide light to every station zone and define a comfort level to passengers and staff. They were designed in the first half of the 20th century. Now they do not meet any modern requirements. Many of these illumination devices are lost or replaced by more efficient illumination devices that totally misrepresent the original appearance of stations. Appearance of LED light sources allows to optimize luminous environments and to save the historical appearance of illumination devices and stations. This paper shows the ways of problem-solving in case of the entrance hall and the inter-escalator anteroom at Krasnye Vorota (station).

An analysis of escalator areas illumination of the Moscow underground is given. Disadvantages of the existing illumination system are shown, and ways of their elimination are proposed using upgrading illumination devices with preservation of a “historical” image of the latter.
