after visiting the New York City Subway prompted all works to be cancelled and the shallow stations to be reopened with a westward surface track creating the Filyovskaya line. Although the construction of surface stations reached the western districts of Moscow by the mid-1960s, the Russian winter climate took its toll on the operation and management of the Filyovskaya line. In addition to that, the northwestern districts of Moscow, including the Strogino and Mitino housing estates, which were built in the 1970s and 1980s remained isolated. All of the bus and tram routes in that area led to the Shchukinskaya and Tushinskaya stations of the Tagansko–Krasnopresnenskaya line, which made the latter line one of the busiest in the system. By the mid-1980s it was clear that a complex reconstruction was needed to solve the transport problems in Western Moscow. The first plans to link Strogino to the city center were formed back in the 1960s before they were even built. The mid-1960s general plan proposed the new Tagansko–Krasnopresnenskaya line to have a branch from Polezhayevskaya which would continue westwards into Khoroshovo, Serebryany Bor and ultimately Strogino, and afterwards towards Krasnogorsk. Despite Polezhayevskaya being opened in 1972 with three tracks, it was never to be used for its intended purposes. Owing to the disadvantages of the over-congested centre, a set of chordial and semi-chordial lines that would bypass the city centre and the Koltsevaya line was proposed in 1980s. The Mitinsko–Butovskaya line would begin in Mitino, continue south to Strogino and then to Khoroshovo, Fili, along the Moscow Little Ring Railway via Luzhniki before finally coming south to the district of Biryulyovo and continuing into Butovo. In 1988 building commenced on the extension of Arbatsko–Pokrovskaya line to Park Pobedy which was to be a cross-platform interchange with the new chord. At the same time, construction was started in earnest on three stations of the chord: Strogino, Volokolamskaya and Mitino along with a new bridge across Moskva River between Strogino and Volokolamskaya and a depot after Mitino. In 1990s following the collapse of the Soviet Union state funding was cut to negligible amounts, and the construction of the chordial lines was permanently halted. In March 1993, Moscow Metro published a revised plan for what was to replace the chord. The already started section in Mitino and Strogino should be completed and the hooked on to the Filyovskaya line, and for the next
