The 81-775 series (named Moskva-2020, Russian: Москва-2020) is a family of metro cars designed by Metrowagonmash. The series consists of three types: The 81-775 (head motor car), the 81-776 (intermediate motor car), and the 81-777 (intermediate non-motor car). It has been in service on the Moscow Metro since 2020.

81-775.2

The 81-775.2 series (named Moskva-2024 & Moskva-2026) is a facelifted/modified version introduced in 2024. The first train was delivered to the Moscow Metro in December 2023.[1][2] Regular passenger operation of the 81-775.2 began on 11 March 2024 on the Zamoskvoretskaya line, replacing older 81-717 trains. As of March 2026, the replacement of the line's rolling stock has not yet been completed, one of the reasons being the opening and extension of the Troitskaya line. In December 2025, the new 81-775.2 "Moskva-2026", a minor facelift of the 81-775.2 "Moskva-2024", entered regular passenger service on the same Zamoskvoretskaya line.
