The Kalininsko-Solntsevskaya Line (Кали́нинско-Солнцевская ли́ния, IPA: [kəˈlʲinʲɪnskə ˈsontsəfskɐjə ˈlʲinʲɪjə]) (Line 8) is a line of the Moscow Metro, currently consisting of two separate parts. It was opened as the eastwards Kalininskaya Line in 1979, with the first stations of the western Solntsevsky radius opening in 2014. Presently there are 8 stations on the eastern section and 5 on the western section. The two parts are planned to be joined by 2020. To distinguish the 2 sections, the newer west section is identified as Line 8A.
The line's pilot stage, which would see it extending from Taganskaya through Lefortovo and into the eastern districts of Perovo, Novogireevo and Veshnyaki was opened for the 1980 Moscow Olympics. The line bears all traits of the late 1970s architecture and engineering. No longer pressed for economy designs and aesthetics, the architects were given full freedom to use advanced materials.
The engineers were able to introduce new designs, particularly for the Column stations of Marksistskaya and Aviamotornaya which were built without ventral crosspieces allowing a huge economy in time by abandoning the use of tubings. The shallow column station of Novogireevo further demonstrated its parting with previous centipede roots by increasing inter-column width from six to seven and a half metres.
What makes the line unique is its name, as it was originally named after partially passing the Kalinin district, which disappeared in the 1990s. Thus the line is the only in Moscow which carries the name of a figurehead, Mikhail Kalinin rather than the area it serves.
In 1986 the line's first extension opened, with the station Tretyakovskaya, the third cross-platform transfer in Moscow Metro was set up this way. It was planned for the line to continue and link up with the Arbatskaya station of the Arbatsko-Pokrovskaya Line, allowing it to be split and the old route Aleksandrovsky Sad—Ploshchad Revolyutsii route to be reused, whilst the Kalininskaya line, now operating to Kievskaya would extend southwestwards.
This was not to be realised, and the western extension plans stalled for more than two decades due to the financial instability of the 1990s and other priorities.
|Marksistskaya–Novogireevo||30 December 1979||11.4 km|
|Marksistskaya–Tretyakovskaya||25 January 1986||1.7 km|
|Novogireyevo–Novokosino||30 August 2012||3.2 km|
|Park Pobedy–Delovoy Tsentr||31 January 2014||3.4 km|
|Park Pobedy–Ramenki||16 March 2017||7.3 km|
|Total:||13 Stations||27 km|
|Kaluzhsko-Rizhskaya Line||Tretyakovskaya (cross-platform interchange)|
|Arbatsko-Pokrovskaya Line||Park Pobedy (cross-platform interchange)|
The line is served by the Novogireevo depot (№ 12). 36 eight-carriage trains of the newest 81-760/761 model are running on the line. It was also served by one new 81-717.6K/714.6K eight-carriage train in 2007-2011 and by two 81-717.5M/714.5M in 2009-2011, but the most trains till 2012 were old 81-717/714, built between 1979 and 1983. In 2012-2013 all 81-717/714 trains were replaced by new 81-760/761 (called "Oka") trains. The last 81-717/714 train emerged on the line in April 2013.
Recent developments and future plans
The line currently exists as a single radius, but for a long time an extension through the city centre and then on westwards has been planned.
The first part of the Solntsevsky radius, between Park Pobedy and Delovoy Tsentr (with a transfer to Vystavochnaya), opened in January 2014. It is not yet connected to the rest of Kalininskaya Line. A further extension of this line further south from Park Pobedy to Ramenki was opened on 16 March 2017. The currently planned terminus will be Rasskazovka, about 5 km from Vnukovo International Airport.
The gap between Delovoy Tsentr and Tretyakovskaya is planned to be connected via the city center by 2020.
The planned stations on this route are (from east to west):
- Volkhonka (with a transfer to Kropotkinskaya on the Sokolnicheskaya Line)
- Plyushchikha (with a transfer to Smolenskaya on the Arbatsko-Pokrovskaya Line)
- Dorogomilovskaya (with a possibility of constructing a new transfer station at Koltsevaya Line)
