The beginning of the [[Cold War]] led to the construction of a deep section of the [[Arbatsko-Pokrovskaya Line]]. The stations on this line were planned as shelters in the event of nuclear war. After finishing the line in 1953 the upper tracks between [[Ploshchad Revolyutsii]] and [[Kiyevskaya (Filyovskaya)|Kiyevskaya]] were closed, and later reopened in 1958 as a part of the [[Filyovskaya Line]]. The stations, too, were supplied with tight gates and life-sustenance systems to function as proper nuclear shelters.

In the further development of the Metro the term "stages" was not used any more, although sometimes the stations opened in 1957–1959 are referred to as the "fifth stage".<ref>{{Cite web |title=Moscow Metropolitan - Страницы из метростроевской летописи и планы метростроения |url=https://news.metro.ru/letopis.html |access-date=2025-03-09 |website=news.metro.ru}}</ref>
