Source-derived summary

The Koltsevaya line (Russian: Кольцева́я ли́ния, Ring line, IPA: [kəlʲtsɨˈvajə ˈlʲinʲɪjə]) (Line 5; Brown Line) is a line of the Moscow Metro system in Moscow, Russia. The line was built in 1950–1954 as a circle route orbiting central Moscow, and became crucial to the transfer patterns of passengers. The stations on the line were built at the height of Stalinist architecture, and include Komsomolskaya, Novoslobodskaya and Kiyevskaya.

History

In the initial plans of the Metro's development, there was no provision for the Circle line. Instead it was planned for complete cross-city routes ("diameters") to cross the city centre with interchange stations at their intersections. However, after the opening of the second stage in 1938, it was clear from the excessive loads on those junctions, that this plan would be insufficient to deal with the growing number of passengers as the system expanded. An urban legend suggests that Joseph Stalin himself suggested the line when he placed a coffee cup on the original development map (with no ring) and then lifting it and leaving a circular stain around the centre of the city and said "It's your main fault, it should be built". It is thought this is the reason for the line's brown colour on all metro maps.

In principle, the alignment of the ring was also debated, whether to use the Garden Ring avenue that encircles the centre or a wider circumference. In the end, it was decided to partially align the southern path along the Sadovoye Koltso, and let the northern part deviate to connect most of Moscow's rail terminals.

Editorial analysis

Why this record matters

“Koltsevaya line” is worth following because a concise public description often conceals a longer documentary argument. Here, Koltsevaya, line and Moscow provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q831673. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1950, 1954 and 1938.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
