The Koltsevaya Line (Russian: Кольцева́я ли́ния), also known as the Ring Line, is a line of the Moscow Metro. The southern portion of the cicumfrence is aligned along the Sadovoye Koltso (Garden Ring), an avenue encircling the city centre. The northern half deviates from the ring avenue to connect most of the Moscow rail terminals. The Koltsevaya Line intersects all nine of the Metro's main radial lines, providing an alternative transfer point between them. On Metro maps it is normally coloured brown.

The Koltsevaya Line was built in three phases between 1950 and 1954 and contains some of the most extravagant stations in the entire system, such as Komsomolskaya and Novoslobodskaya. Presently it one of the busiest.

Rolling stock

The line is serviced by the Krasnaya Presnya depot (#4) and was the first one to adopt the 81-717/714 trains in 1978. Presently 34 six-carriage trains are assigned to it.

Recent developments and future plans

Today the line is one of busiest, and the ever-rising passenger flows during rush hours are hard on the system as most of the stations are over half a century old. Most were built with very short central halls and many lack second exits to the surface. In 1998 a second exit was opened at Belorusskaya and there are plans to equip Park Kultury and Komsomolskaya with similar exits.

Also recently the station Novoslobodskaya had major restoration work carried out, including replacement of lighting and retouching on the stained glass masterpieces. The vestibule of Taganskaya in 2005 was closed to replace old escalators and upgrade with new technology.

Two stations are planned to be opened on the Koltsevaya Line to provide transfer points to planned Dmitrovskiy and Stroginskiy radii. Suvorovskaya, located between Prospekt Mira and Novoslobodskaya, is to connect with the Dostoyevskaya station of the Lublinsko-Dmitrovskaya line (currently Lyublinskaya). However, though construction has begin on Suvorovskaya it is currently frozen for financial reasons and the station will not be complete in time for the opening of the Dmitrovskiy radius in 2008.

The other planned station, presently dubbed Rossiyskaya, is to be built between Krasnopresnenskaya and Kievskaya to become a transfer point to the Stroginskiy radius. Construction is not expected to begin until 2015, however, and as with the Dmitrovskiy the Stroginskiy radius will most likely open without a transfer point.
