Tagansko-Krasnopresnenskaya Line

The Tagansko-Krasnopresnenskaya (formerly Zhdanovsko-Krasnopresnenskaya) is a line of the Moscow Metro. Roughly it cuts through Moscow on a Northwest-Southeast axis. The line was initially opened as two separate radii lines in 1966 and 1972, and only in 1975 did they connect in the central section. The line was also the first one in Moscow to have a cross-platform transfer. Presently it is the busiest line in the metro with a daily passenger traffic of over two million.

The Kitay-Gorod transfer is a cross-platform one.

Rolling Stock

The line is served by two depots, Planernoe (№ 6) and Vykhino (№ 11). Respectively 36 and 34 eight carriage trains are assigned to them. Most of the trains are Ezh3 and Em-508T models which were received new from 1974, currently all of the trains are being slowly modernised extending the service life by another 15 years.

Recent developments and Future plans

The south-eastern termius, Vykhino, is a surface station which was combined with a railway station to make a large transfer point. This made it the busiest station on the line and at peak hours it was cramped beyond the capabilities that it was built in. In 2004 a serious reconstruction of the platforms allowed to increase their area, and also gave it a desirable facelift. An extension is also planned there with one station to Zhulebino (also called Pronskaya). Although construction is yet to begin, it is expected to open in 2010. Currently only projects exist for a northern extension to Severnoje. Also between Schukinskaya and Tushinskaya, another station Volokolamskaya was built, however it was not opened in 1975 and remained derelict ever since. The station carcass is complete but it lacks an exit to the surface. Although there are no plans for its opening in the nearby time, as the area is being actively built by housing estates, that may soon change. Also it is unclear of the fate for the third path on the Polezhaevskaya station originally planned as a branch to the silver pinewood park (Serebryanyi Bor). Future plans might however cause the mini-metro to use the path.
