Moscow Metro Line 2: 2023 Metrowagonmash 81-775.2/776.2/777.2 “Moscow-2024“ train on testing

It will soon to be put in service on Line 2 this Spring (March probably) or 1st February (as rumors saying plus I don’t believe that information) and future Line 16. After this train is in service the “2020“ version will send back to Line 6 or 11. Finally this line getting new trains 45 years later since 81-717/714 trains started their service in 1979 (after Line 5 in 1978). Sadly only 10 by next year.
