81-765 series (named Moskva, Russian: Москва́) are types of metro cars designed by Metrowagonmash in Russia. The series consists of three types of cars: 81-765 (head motor car), 81-766 (intermediate motor car) and 81-767 (intermediate non-motor car). The Moskva is currently in service on five systems, including the Moscow Metro, Kazan Metro, Baku Metro, Tashkent Metro and Minsk Metro. It was also the basis for the 81-725 series, which is used on the Saint Petersburg Metro. The Moskva entered production in 2016 and entered service in the Moscow Metro in 2017. In Belarus, it is named the Minsk-2024.
