the territory of the Moscow Oblast. In 2008 the stations Slavyansky Bulvar and a redesigned Kuntsevskaya opened, and Filyovskaya line's underground stations Molodyozhnaya and Krylatskoye were annexed by the Arbatsko–Pokrovskaya line. At the same time, the extension to Strogino was completed, nearly doubling the length and passenger load of Arbatsko–Pokrovskaya line as a result. In 2009, the line finally reached Mitino, with an additional station Pyatnitskoye Shosse opening further on in 2012. The East Some of the stations in the eastern section of the line are very old and many were built during the 1940s, and their age shows clearly in their appearance as well as their operational technology such as escalators. In May 2005 the Semyonovskaya station was closed for a year to replace its escalators and also to completely renovate and upgrade its vestibule. Elektrozavodskaya was closed in May 2007 and re-opened in late November 2008. The next station to be refurbished on the Pokrovsky radius is also the busiest, Baumanskaya, which was planned for closure in spring 2009, but has been rescheduled to 2015. Second entrances were also planned for the majority of the stations, but these plans have been cancelled. In addition to the renovation works, new stations were planned for the line. In 1938, on the first stage of the line between Ploshchad Revolyutsii and Kurskaya, reservations for two future stations were built. Named Maroseika and Pokrovka, these two stations were planned to be opened at a later date. The former station in particular would have been very important as it would have facilitated a direct transfer to the Kitay-gorod station complex of the Kaluzhsko–Rizhskaya and Tagansko–Krasnopresnenskaya lines. Construction of these stations is not yet planned to occur. In the very east another extension is proposed to Golyanovo. The Shchyolkovskaya station recently received a very major restoration with the old ceramic tiles replaced with modern aluminium panels.
