Zamoskvoretskaya line

The Zamoskvoretskaya line (Russian: Замоскворе́цкая ли́ния, IPA: [zəməskvɐˈrʲɛtskəjə ˈlʲinʲɪjə]), formerly Gorkovsko–Zamoskvoretskaya (Го́рьковско-Замоскворе́цкая) (Line 2; Green Line), is a line of the Moscow Metro in the Moscow Oblast of Russia. Opened in 1938, chronologically it became the third line in the metro system despite being labeled second. There are 24 stations on the Zamoskvoretskaya line, and it spans 42.8 kilometres (26.6 mi), roughly crossing Moscow in a north–south direction. A normal trip along the entire line takes 55 minutes, with the trains on the line averaging 42 kilometres per hour (26 mph). While most of the line is underground, there are some pockets of surface-level or above-ground track, mainly at the point where the line crosses the Moskva River. Many of the line's stations are renowned for their grand interiors and intricate architectural features and have been classified as objects of cultural heritage.
