^Four central stations of the Filyovskaya Line – Alexandrovsky Sad (formerly Imeni Kominterna), Arbatskaya,
Smolenskaya and Kiyevskaya – were originally opened in 1935–1937, when they were a branch of the Sokolnicheskaya Line. Between 1938 and 1953, they were part of the Arbatsko-Pokrovskaya Line. The stations were closed between 1953 and 1958 and then reopened as part of the (new) Filyovskaya Line.
A line branching off the Filyovskaya is in operation (as of July 2009), starting from the Alexsandrovsky Sad Station and continuing on the Filyovskaya Line to Kiyevskaya Station, where it departs to stop at the (new) Vystavochnaya and Mezhdunarodnaya Stations.

The line itself is not considered part of the underground metro, as the infrastructure, rolling stock and staff belong to Russian Railways; as such, its length and number of stations are not included in the total tally.
