MS-IV in Sovetsk, Tram monument in Sovetsk, Russia

The MS-IV is a decommissioned tram car displayed in Sovetsk. This Soviet-era vehicle was manufactured at the Putilov plant, a major Russian producer of electric streetcars.

The Putilov plant in Saint Petersburg started manufacturing trams in the 1800s. The MS series was developed during the Soviet period as streetcars expanded across Russian cities.

The car carries the number 12, though it was built in 1933 at the Putilov plant in Leningrad and ran there as M-52 and M-26. Exhibitions of photographs about the town's past and present are held inside it. Beside it stands a lamp post with street names in Russian and German.

The vehicle sits as a fixed monument at a specific location in town. Visitors can view the historical car from the outside and study the construction style of the Soviet era.

The car is a Putilov plant MS-4 built in 1933, not a Tilzit vehicle: it ran in Leningrad as M-52 and M-26, was renumbered 2601 for a planned café, and came to Sovetsk from Saint Petersburg's Museum of Electric Transport in 2012. Local historians dispute its authenticity, since Tilzit's lines were narrow gauge (1000 mm) and this car sits on 1524 mm bogies.
