81-775 series (named Moskva-2020, ) are types of metro cars designed by Metrowagonmash. Series consist of three types â 81-775 (head motor car), 81-776 (intermediate motor car) and 81-777 (intermediate non-motor car). The series has been in use by Moscow Metro since 2020.
81-775.2 series (named Moskva-2024 & Moskva-2026) is a facelift/modification from 2024. First train was delivered to Moscow Metro in December 2023. The regular passenger operation of 81-775.2 began on 11th March 2024 on Zamoskvoretskaya line to replace older 81-717 trains. At the moment of March 2026, the replacement of line's rolling stock is not yet done, and one of reasons of that is the opening and the extension of Troitskaya line. In December 2025, the new 81-775.2 "Moskva-2026", a very small facelift of 81-775.2 "Moskva-2024" began regular passenger service on the same Zamoskvoretskaya line.
