on the Kakhovskaya until 2019 and Lublin-Dmitrov lines: 6 81-720/721 trains built between 1991 and 2002 on Kakhovskaya Line and 3 81-720.1/721.1 trains built in 2004 on Lyublinsko-Dmitrovskaya Line. No further production runs were made and the Moscow Metro chose instead to purchase more 81-717/714.5M and brand new 81-740/741 models. The rest of the service on the Lublin-Dmitrov line is provided by 81-717/714.5M and 81-717/714.6K trains. It is planned to eventually transfer all 81-720/721.1 cars to the Kakhovskaya line. Several surplus 81-720/721 cars remained on JSC "Metrovagonmash" property until 2010, before being scrapped to give space for the ongoing production of the future 81-760/761 cars, and one 81-721 car remained stored in the "Krasnaya Presnya" depot prior to disposal in August 2013. The remaining cars would later be scrapped due to reliability issues, with the final train being withdrawn in August 2019.
