The genocidal siege of Leningrad by Nazi Germany, for more than 28 months from 1941-1944, caused the death of nearly 3 million Leningrad citizens and Russian soldiers; the invasion was a key formative event in Russia's view of the world today. The trams moved food, other goods and people around the city during the siege. The Nazis deliberately bombarded electric power generating stations to shut down the trams and everything else, resulting in widespread starvation and even a little cannibalism. Even so, the Russians eventually ejected and defeated the invading Nazi army, truly remarkable under the circumstances. In the windows of this tram, you can see actual photos from the siege of people walking next to inoperable trams and dragging dead bodies through the snow. Nearby, along Prospekt Stachek, you can see a tank that participated in the defense of Leningrad, several concrete bunkers that housed defensive artillery, and the Krasnenkoe Cemetery holding many victims of the siege and some Heroes of the Soviet Union from the war. Of course there is a wealth of textual and image material on the siege on the internet.
