Kaluzhsko-Rizhskaya line state of use in use
The Kaluzhsko-Rizhskaya line (Russian: Калу́жско-Ри́жская ли́ния, IPA: [kɐˈɫuʂskə ˈrʲiʂskəjə ˈlʲinʲɪjə]) is a line of the Moscow Metro, that originally existed as two separate radial lines, Rizhskaya and Kaluzhskaya opened in 1958 and 1962, respectively. Only in 1971 were they united into a single line as the central section connecting the stations Oktyabrskaya to Prospekt Mira was completed. It was also the first line in Moscow to have a cross-platform transfer. The Rizhsky radius is roughly aligned with a northern avenue Prospekt Mira, while the Kaluzhskiy radius generally follows a southwestern street Profsoyuznaya Ulitsa. Presently, the Kaluzhsko-Rizhskaya line is the third busiest in the system with a passenger traffic rate of 1.015 million per day. It has a bi-directional length of 37.8 kilometres (23.5 mi), and a travel time of 56 minutes, typically it is coloured orange on Metro maps and numbered 6.Timeline
Transfers
Rolling stock
The line is served by two depots, Kaluzhskoe (№ 5) and Sviblovo (№ 10). Most of the trains are 81–717.5/714.5 models which were received new from 1987, however 12 of them are the new 81-717.5M/714.5M which were added to Sviblovo's park in 1996/1997. In 2017, the Moscow Metro began replacing the 81–717.5/714.5 and 81-717.5M/714.5M models with 81-760/761s (Oka). The 81-760/761s stopped being used on the line on 22 August 2018. In 2018, Moscow Mayor Sergey Sobyanin announced that the next-generation 81-765/766/767 (Moscow) trains would operate on the line from 2019, and within five to six years the old rolling stock would be entirely replaced. In May 2018, the first 81-765/766/767 train began operating on the line, ahead of schedule. In December 2020, the first 81-775/776/777 train began operating on the line.
Subway car types used on the line over the years:Recent developments and future plans
Currently the line spans through the entire city and no extensions are planned in the nearby future. However several projects exist. The first one was to connect the town of Mytishchi in the Moscow Oblast with the Moscow Metro, this was however declared unnecessary by the mayor of the city. Another one was to extend from Bitsevsky Park to Annino of the Serpukhovsko-Timiryazevskaya line, however it is unlikely this will be realized due to the preserved area of the Bitsa Park, and a newer project to bring the Butovskaya Light Metro line to the southern radius.
The lack of transfer to the Serpukhovsko-Timiryazevskaya line has led to a plan to build Yakimanka station between Oktyabrskaya and Tretyakovskaya, which will offer a transfer to Polyanka.
Several projects also exist to modernize the older stations. A second entrance was added to VDNKh in 1997 and Akademicheskaya has had a restoration of its ceramic tiled walls replacing them with aluminium planes. Recently it has emerged that the Moscow circular railway will be converted into a form of urban transport. If so then the conserved transfer from Leninsky Prospekt to the railway station Ploschad Gagarina will be opened.
