M2 train in St. Peterburg

Here is a Metro train in St. Peterburg (then Leningrad), on the line M2. I believe this is in the city center. I was trying to get a metro to Ploshchad Aleksander Nevskogo, so I would have had to transfer at Nevskiy Prospekt and cross to Gostinyiy Dvor to take M3 the rest of the way
