underground. The Filyovskaya line consisting of four stations opened in 1958. The Filyovskaya line turned out to be an unfortunate experiment, and in 2003, more than 50 years after the western terminus opening, the Park Pobedy station was opened. It took 15 years to construct the deepest station of the Metro (though most of the time its construction was on hold due to the shortage of funding in the late 1990s). In 2008 the western part of the line was extended further to the district of Strogino annexing some of the Filyovskaya line stations and extending the existing line by approximately . At the end of 2009, the Arbatsko–Pokrovskaya line became the first line of the system to cross the borders of Moscow providing rapid transit service to the city of Krasnogorsk.

Name changes Transfers Rolling stock The line is served by the Izmailovo depot (#3) and it presently has 43 seven carriage trains assigned to it. Historically none of the trains that used on the line have been new rolling stock. Rather most of its rolling stock has consisted of older train models that were no longer being used on other lines when those lines upgraded their rolling stock to newer ones. Thus all trains that are retired from this line are sent to the scrapyard. For example, the Am and Bm types in 1975 and the D type in 1995 and currently the E type. Currently the line is being served by 81-74x series 5-car train sets with .1 and .4 modifications. Subway car types used on the line over the years: -Series A, B: 1938 – 4 February 1975 -Series G: 1941–1950, 1954–1958, 1970 – 4 February 1975 -Series D: 1973 – 2 June 1995 -Series E: 1990–2005;January – 29 February 2008 (carriage number 3605) -Series Ezh, Em-508 and Em-509: 1990 – 9 August 2010 -Series 81-740.1/741.1: 26 December 2006 – present -Series 81-740.4/741.4: September 2009 – present -Series 81-760/761: 23 September 2015 – 30 August 2018 Recent events and plans The West In 1953, after the closure of the shallow stations between Ploshchad Revolyutsii and Kievskaya and their replacement with the present deep ones, more westward extensions were planned to begin.
